Introduction
The Qisda UH100 Diagnostic Ultrasound System (hereinafter called
“system”) is an easy-to-use, portable ultrasound imaging instrument
intended for use by a qualified operator for ultrasound evaluation and
clinical analysis. The miniaturized ultrasound system runs on the tablet
computer using multi-touch operation. Commonly used applications
include: abdomen, cardiac, small organ (e.g., breast, testes, thyroid),
heart soft tissue, vascular, musculoskeletal (e.g., conventional and
superficial), pediatric, fetal, cephalic and Ob/Gyn.
About ultrasound
Ultrasound is a diagnostic imaging technology done by sending sound
waves into the body tissue using a transducer. Based on the various
degrees of sound echoing off different tissues, the ultrasound image is
formed and displayed. To make a correct diagnosis based on scans, the
ability of the operator and the quality of images are equally important.
The system is equipped with an ultrasound software that helps a trained
operator perform precise image adjustments and adequate control
settings applied during the exam.
The ultrasound software supports various scan modes to work with
various applications and purposes. For detailed instructions on the
functions each mode provides, please refer to the subsequent chapters.
Medical purpose
The system is a general purpose ultrasound system which transmits
and receives ultrasound signal from the transducer, then composites
and displays real-time echo images on the monitor. By moving the
transducer, the system displays the real-time anatomy structure of the
patient’s body on the screen. This valuable information helps operators
to diagnose and treat a variety of diseases and conditions.
The system in no way interprets these images or provides a medical
diagnosis of the patient being examined. It is intended for use by a
qualified physician for evaluation by ultrasound imaging or fluid flow
analysis of the human body.

Biological safety
This product, as with all diagnostic ultrasound equipment, should be
used only for valid reasons and should be used both for the shortest
period of time and at the lowest power settings necessary (ALARA - As
Low As Reasonably Achievable) to produce diagnostically acceptable
images. The AIUM offers the following guidelines:
Clinical Safety Quoted from AIUM
Approved March 26, 1997
Diagnostic ultrasound has been in use since the late 1950s. Given its
known benefits and recognized efficacy for medical diagnosis, including
use during human pregnancy, the American Institute of Ultrasound in
Medicine herein addresses the clinical safety of such use.
There are no confirmed biological effects on patients or instrument
operators caused by exposures from present diagnostic ultrasound
instruments. Although the possibility exists that such biological effects
may be identified in the future, current data indicate that the benefits to
patients of the prudent use of diagnostic ultrasound outweigh the risks,
if any that may be present.
Safety information RF safety 25
Heating
Elevating tissue temperature during obstetrical examinations creates
medical concerns. At the embryo development stage, the rise in
temperature and the length of time exposed to heat combine to
determine potential detrimental effects. Exercise caution, particularly
during Color Doppler imaging exams. The Thermal Index (TI) provides a
statistical estimate of the potential temperature elevation (in centigrade)
of tissue temperature. Three forms of TI are available: TIS, for soft tissue
exposures; TIB, for instances when bone lies near the beam focus; and
TIC, for the heating of bone situated close to the transducer.
Cavitation
Cavitation may occur when sound passes through an area that contains
a cavity, such as a gas bubble or air pocket (in the lung or intestine,
for example). During the process of cavitation, the sound wave may
cause the bubble to contract or resonate. This oscillation may cause the
bubbles to explode and damage the tissue. The Mechanical Index (MI)
has been created to help operators accurately evaluate the likelihood of
cavitation and the related adverse effects.
Safe scanning guideline
OO
Ultrasound should only be used for medical diagnosis and only by
trained medical personnel.
OO
OO
Diagnostic ultrasound procedures should be done only by personnel
fully trained in the use of the system, in the interpretation of the
results and images, and in the safe use of ultrasound (including
education as to potential hazards).
Operators should understand the likely influence of the machine
controls, the operating mode (e.g. B mode, Color Doppler or
Spectral Doppler) and the transducer frequency on thermal and
cavitation hazards.
OO
Use a low output power default setting for each new patient. Output
should only be increased during the examination if penetration is still
required to achieve a satisfactory result, and after the Gain control
has been adjusted to its maximum value.
OO
Maintain the shortest examination time necessary to produce a useful
diagnostic result.

Take particular care to reduce output and minimize exposure
time of an embryo or fetus when the temperature of the mother is
already elevated.
Take particular care to reduce the risk of thermal hazard during
diagnostic ultrasound when exposing an embryo less than eight
weeks after gestation, or the head, brain or spine of any fetus or
neonate.
Do not use endocavity transducers if there is noticeable self-heating
of the transducer before insertion. If the following system message
displays during a real-time scan, cease the current scan.
Although applicable to any transducer, take particular care during
trans-vaginal exams during the first eight weeks of gestation.
OO
During continuous operation, the system temperature may become
too high. If the following system message displays during a real-time
scan, touch OK and the system enters frozen imaging screen. To
resume scanning, wait until the system engine cools down.
OO
Operators should continually monitor the on-screen thermal index (TI)
and mechanical index (MI) values and use control settings that keep
these settings as low as possible while still achieving diagnostically
useful results. In obstetric examinations, TIS (soft tissue thermal
index) should be monitored during scans carried out in the first eight
weeks after gestation, and TIB (bone thermal index) thereafter. In
applications where the transducer is very close to bone (e.g. transcranial applications), TIC (cranial thermal index) should be monitored.
OO
MI> 0.3 Minor damage is likely to happen to neonatal lung or
intestine. If such exposure is necessary, reduce the
exposure time as much as possible.

containing gas microspheres is being used. There is
a theoretical risk of cavitation without the presence of
ultrasound contrast agents. The risk increases with MI
values above this threshold.

OO
Diagnostic ultrasound has the potential for both false positive and
false negative results. Misdiagnosis is far more dangerous than any
effect that might result from the ultrasound exposure. Therefore,
diagnostic ultrasound should be performed only by those with
sufficient training and education.
OO
Non-diagnostic use of ultrasound equipment is not generally
recommended. Examples of non-diagnostic uses of ultrasound
equipment include repeated scans for operator training, equipment
demonstration using normal subjects, and the production of souvenir
pictures or videos of a fetus. For equipment of which the safety
indices are displayed over their full range of values, the TI should
always be less than 0.5 and the MI should always be less than 0.3.
Avoid frequent repeated exposure of any subject. Scans in the first
trimester of pregnancy should not be carried out for the sole purpose
of producing souvenir videos or photographs, nor should their
production involve increasing the exposure levels or extending the
scan times beyond those needed for clinical purposes.
Temperature display for transducers intended for internal
use
For E94A transducers used for internal applications, e.g. the endocavity
transducers, the transducer tip temperature is displayed on the screen.
To protect the patient against the harm of excessive temperature, the
system automatically turns off the transducer when the transducer
temperature reaches a threshold temperature.
Waterproof and dustproof ratings
The system has a degree of protection from ingress of water and
particulate matter, but the tablet is not approved for use where it would
be exposed to liquids. If it is used in environments where it might be
exposed to liquids, the tablet must be covered by ad drape, such as s
a Civco #610-1037. These environments include, but are not limited to
outpatient and private office procedures such as biopsies, office visits,
and other traditional, non-invasive scanning.

Table 4 MI/TI generating from applicable transducer/mode combinations
Track-3 follows the Output Display Standard for systems which include
fetal Doppler applications. The acoustic output will not be evaluated on
an application-specific basis, but the global maximum de-rated Ispta
must be ≤ 720 mW/cm2 and either the global maximum MI must be
≤ 1.9, or the global maximum de-rated Isppa must be ≤ 190 W/cm2. An
exception is for ophthalmic use, in which case the TI=max (TIS, TIC) is
not to exceed 1.0; Ispta.3 ≤ 50 mW/CM2, and MI ≤ 0.23. Track-3 gives
the operator the freedom to increase the output acoustic power for a
specific exam, and still limit output acoustic power within the global
maximum de-rated Ispta ≤ 720 mW/cm 2 under an Output Display
Standard.
The increments are for the display of thermal indices, if displayed is
no more than 0.2 for values of indices up to 2.0 and 0.5 for values of
indices above 2.0. The system design allows full software control of
the acoustic output, entry of new patient identification data or change
from a non-foetal to a foetal application, and the system may switch to
an appropriate default setting upon powering on. These default setting
levels are established before shipping and may be reconfigured by the
operator.
Safety information Understand the MI/TI display 30
For any diagnostic ultrasound systems, Track-3 provides an Output
Indices Display Standard. The diagnostic ultrasound systems and its
User Manual contain the information regarding an ALARA (As Low
As Reasonably Achievable) education program from the clinical enduser and the acoustic output indices, MI and TI. The MI describes
the likelihood of cavitation, and the TI offers the predicted maximum
temperature rise in tissue as a result of the diagnostic examination. In
general, a temperature increase of 2.5°C must be present consistently at
one spot for 2 hours to cause possible fetal abnormalities. Avoiding a local
temperature rise above 1°C should ensure that no thermally induced
biologic effect occurs. When referring to the TI for potential thermal
effect, a TI equal to 1 does not mean the temperature will rise 1°C. It only
means an increased potential for thermal effects can be expected as the
TI increases. A high index does not mean that bioeffects are occurring,
but only that the potential exists and there is no consideration in the TI
for the scan duration, so minimizing the overall scan time will reduce
the potential for effects. These operator control and display features
move the safety responsibility from the manufacturer to the operator. So
it is very important to have the diagnostic ultrasound systems display
the acoustic output indices correctly and the well-educated operator to
interpret the value appropriately.
RF: De-rating factor
In Situ intensity and pressure cannot currently be measured. Therefore,
the acoustic power measurement is normally done in the water tank, and
when soft tissue replaces water along the ultrasound path, a decrease
in intensity is expected. The fractional reduction in intensity caused by
attenuation is denoted by the de-rating factor (RF),
RF = 10 (-0.1 a∙f∙z)
Where a is the attenuation coefficient in dB cm -1 MHz -1 , f is the
transducer center frequency, and z is the distance along the beam axis
between the source and the point of interest.
De-rating factor R F for the various distances and frequencies with
attenuation coefficient 0.3 dB cm-1 MHz-1 in homogeneous soft tissue is
listed in the following table. An example is if the operator uses 7.5 MHz
frequency, the power will be attenuated by .0750 at 5 cm, or 0.3 x 7.5 x
5 = -11.25 dB. The De-rated Intensity is also referred to as ‘.3’ at the end
(e.g. Ispta.3).

Unscanned
Emission of ultrasonic pulses occurs along a single line of sight and is
unchanged until the transducer is moved to a new position. For instance,
the PW and M mode.
TI
TI is defined as the ratio of the In Situ acoustic power (W.3) to the
acoustic power required to raise tissue temperature by 1°C (Wdeg),
TI = W.3 / Wdeg
Three TIs corresponding to soft tissue (TIS) for abdominal; bone (TIB)
for fetal and neonatal cephalic; and cranial bone (TIC) for pediatric and
adult cephalic, have been developed for applications in different exams.
An estimate of the acoustic power in milliwatts necessary to produce a
1°C temperature elevation in soft tissue is:
Wdeg = 210 / fc
For model 1 to 4, where fc is the center frequency in MHz.
Wdeg = 40 · K · D
For model 5 and 6, where K (beam shape factor) is 1.0, D is the aperture
diameter in cm at the depth of interest.
MI
Cavitation is more likely to occur at high pressures and low frequencies
in pulse ultrasound wave in the tissue, which contains a bubble or
air pocket (for instance, the lung, intestine, or scan with gas contrast
agents). The threshold under optimum conditions of pulsed ultrasound
is predicted by the ratio of the peak pressure to the square root of the
frequency.
MI = Pr’ / sqrt(fc)
Pr’ is the de-rated (0.3) peak rare-fractional pressure in Mpa at the point
where PII is the maximum, and fc is the center frequency in MHz. PII is
the Pulse Intensity Integral that the total energy per unit area carried by
the wave during the time duration of the pulse. The peak rare-fractional
pressure is measured in hydrophone maximum negative voltage
normalized by the hydrophone calibration parameter.
Safety information Understand the MI/TI display 33
Display guideline
For different operation modes, different indices must be displayed.
However, only one index needs to be shown at a time. Display is not
required if maximum MI is less than 1.0 for any setting of the operating
mode, or if maximum TI is less than 1.0 for any setting of the operating
mode. For TI, if the TIS and TIC are both greater than 1.0, the scanners
need not be capable of displaying both indices simultaneously. If the
index falls below 0.4, no display is needed. The display increments are
no greater than 0.2 for index value less than one and no greater than 1.0
for index values greater than one (e.g. 0.4, 0.6, 0.8, 1.2, 3).
Display and report in different modes
For B mode
Display and report only MI, and start from 0.4 if maximum MI > 1.0
For Color mode
Display and report only TIS or TIB, and start from 0.4 if maximum TI > 1.0
For Doppler mode
Display and report only TIS or TIB, and start from 0.4 if maximum TI > 1.0
Below is a simple guideline for the operator when TI exceeds one
limit exposure time to 4(6-TI) minutes based on the ‘National Council
on Radiation Protection. Exposure Criteria for Medical Diagnostic
Ultrasound: I. Criteria Based on Thermal Mechanisms. Report No.113
1992’.
Operator control features
The operator should be aware that certain operator controls may affect
the acoustic output. It is recommended to use the default (or lowest)
output power setting and compensate using Gain control to acquire
an image. Other than the output power setting in the Soft Menu, which
has the most direct impact on the power; the PRF (Pulse Repetition
Frequency), image sector size, frame rate, depth, and focal position also
slightly affect the output power. The default setting is normally around
70% of the allowable power, depending on the exam type.
Transducer surface temperature rise

ambient (23°C ± 3°C) of transducers used on the system. The

be operated by someone who has received proper training in the use
and operation of a diagnostic ultrasound system. This system produces
images derived from sound echoes; those images must be interpreted by
a qualified medical professional. This system in no way interprets these
images or provides a medical diagnosis of the patient being examined.
The system has successfully completed compliance tests for IEC 606011:2005 3rd ed., IEC 60601-1-2:2007 3rd ed., IEC 60601-2-37:2007
2nd ed. medical standards for the configuration as originally installed.
To maintain compliance with the stated safety and EMI standards,
we recommends use of medical grade peripherals only. Use of nonmedical grade peripherals will result in non-compliance of safety and
EMI standards. Non-conformance to these standards can produce risks
to the patient and operator of this equipment. We cannot be held liable
for changes to the system topology that no longer conform to the stated
safety and EMI standards. Changes to the system topology may make
it necessary to retest the complete system for compliance to these
standards. The User Manual refers to the potential for connecting the
system to peripherals such as VCRs, TVs, and printers. Note that we
have not performed compliance tests to the stated standards with these
types of devices connected to the system. Any peripheral device, such
as a network connection, etc. connected to the system must conform to
the IEC standards outlined above (i.e., IEC 60601-1:2005 3rd ed., IEC
60601-1-2:2007 3rd ed., and IEC 60601-2-37:2007 2nd ed.)
The system (without peripherals) is suitable for use within the patient
environment, as defined by the following:
OO
OO
The user should never simultaneously make contact with the
patient and the inside of any equipment where a protective cover
of any kind is removed. This includes the protective covers for the
transducer holders containing the ultrasound transducer and power
modules located at the patient table.
When using E94A endocavity transducers, the transducers must be
protected with a transducer sheath.

Figure 4
Patient environment
Portable and mobile RF communications equipment can affect medical
electrical equipment such as the system and should not be used in the
patient environment.
The system should not be used adjacent to or stacked with other
equipment. If adjacent or stacked use is necessary, the system should
be observed to verify normal operation in the configuration in which it
will be used.
If there is a certain frequency of image interference, there is a need of
isolation or filtering of the RF signal.
If the system is interfered by power or signal cable, the image
quality may be reduced or abnormally displayed. Such kind of
interfered images could easily be identified and differentiated from
the physiological characteristics of patient and longer clinical time
consumed but wouldn’t have any diagnostic accuracy issue.
