DVS Dose Verification System
1.1 Product Description
DVS provides an oncologist with information about the actual
radiation dose delivered to a patient’s tissues and organs, and it
provides charts and statistics for comparing the actual dose to the
prescribed dose. DVS uses an implantable dosimeter and an
external reading system to determine the absorbed dose near a
tumor within a patient. DVS provides the oncologist with dose
information that may be used in conjunction with other clinical
information to make decisions regarding treatment plans or to
identify the need for further investigation. The DVS Dosimeter is
able to be visualized and used as a radio-opaque treatment area
marker in IGRT (Image Guided Radiation Therapy) using
ultrasound, kV planar images, kV CBCT (Cone Beam Computed
Tomography), and MV CT/CBCT.
1.2 Intended Use
DVS is intended for use in radiation therapy to verify treatment
planning and radiation dose to tissue and organs in or near the
irradiated areas of a patient.
1.3 Contraindications, Warnings, Cautions, and Notes
See Dosimeter Instructions for Use. The following section explains
the warnings, cautions and notes for DVS.
The terms Warning, Caution, and Note have specific meanings
throughout this manual:
•
A Warning advises against actions or situations that could
result in personal injury or death.
•
A Caution advises against actions or situations that could
damage equipment or produce inaccurate or invalid data.
•
A Note provides useful information regarding the
operation or function of the system.
DVS Dose Verification System
•
The Reader Wand may not be used on patients who are
already implanted with other electronic devices such as
pacemakers, or insulin pumps. The impact of the
potential electronic interference is unknown.
•
Do not allow patients with a DVS Dosimeter to receive
the following treatments: shortwave diathermy,
microwave or therapeutic ultrasound. These could
result in serious injury.
Warnings
The DVS system is not intended to specify adjustments to
dose.
Dose measurement data obtained using the DVS system
should be used in conjunction with existing planning and
delivery tools to verify delivered dose rather than as a stand
alone tool for determining dose adjustments.
•
Electric Shock Hazard – Do not remove the covers of
the Reader or Reader Wand assemblies. Do not open
the case or touch the internal parts. The DVS Reader
and Reader Wand contain no user serviceable internal
parts. Contact the local representative for technical
support and return information.
•
Electric Shock Hazard – The Dose Verification System
is grounded with a three-conductor cable and threeprong plug. Insert the power cable only into a properly
grounded three-contact outlet.
•
Electric Shock Hazard – Do not use in wet
environment. May result in electrocution.
•
Only use the manufacturer-supplied power cord.
•
Replace fuse only with same type and rating: 2 AMP,
250V Time-Lag Fuse. Failure to replace the fuse with
the same type and rating may pose a fire hazard.
Welcome
Contraindications
DVS Dose Verification System
•
The DVS system is not suitable for use in the presence
of a flammable anesthetic mixture with air or with
oxygen or nitrous oxide.
•
Be sure that the cables do not pose a trip hazard.
•
The Reader Wand is not for use in direct contact with
the patient – especially near wounds. Contact with
gowns or other clothing is acceptable. The Reader
Wand is not intended to be sterile. Clean the Reader
Wand after direct skin contact using isopropyl alcoholbased disinfectants.
Cautions
•
Proper use of this system depends on careful reading of
all instructions and labels.
•
Do not use cellular phones or hand held two-way
radios in close proximity to the DVS Reader.
•
Keep CRTs at least 3 feet from the DVS Reader to
prevent the DVS Reader from interfering with the
CRT image. Interference from the CRTs may result in
reduced read range.
•
Turn OFF the system power before connecting or
disconnecting any system components or accessories.
Connecting components with power applied may cause
damage to the connectors or connecting circuitry.
•
If the dosimeter is tested prior to implantation, (1) do
not remove the dosimeter from its package as this will
compromise sterility and (2) do not place the
dosimeters near metal.
•
Do not use a dosimeter near implanted metal objects.
Read range may be compromised.
•
Do not store dosimeters near stray radiation.
•
Enter the predicted dose in cGy, not monitor units.
Entry in monitor units will cause a false error in the
planned vs. actual dose report.
DVS Dose Verification System
Welcome
•
The DVS Reader Wand should not be used within 1-2
feet of large metal objects. Using the Reader Wand
close to large metal objects has the potential to reduce
the read range of the Reader Wand.
•
Do not conduct the pre-dose or post-dose reading while
the patient is on a metal table. If the treatment table is
metal, conduct the pre-dose reading before the patient
is placed on the table and the post-dose reading after
the patient is removed from the table. A metal table or
other metal objects will interfere with the functioning
of the DVS Reader Wand.
•
Take the post-dose reading within 10 minutes after the
end of therapy. Readings taken beyond 10 minutes
decrease dose accuracy.
•
Do not implant the dosimeter deeper than 12 cm or less
than 3 cm from the surface of the skin. Implanting
deeper than 12 cm may result in the inability of the
Reader to communicate with the implanted dosimeter.
Implanting at least 3 cm deep ensures adequate buildup and minimizes potential for mechanical damage.
Notes
The dosimeter is factory calibrated and does not require calibration
during use.

DVS Dose Verification System
2 DOSE VERIFICATION SYSTEM OVERVIEW
The Dose Verification System consists of five components:
•
DVS Dosimeter
•
DVS Insertion Tool
•
DVS Reader
•
DVS Software (Plan and Review Software and Dosimetry
Database)
•
Bar Code Scanner
The implantable dosimeter measures in vivo dose from photon
beam radiation therapy. The dosimeter uses a semiconductor
device called a MOSFET (metal oxide semiconductor field effect
transistor) to measure radiation. Radiation within the human
therapeutic dose range causes a shift in the threshold voltage of the
MOSFET. By measuring the threshold voltage before and after
radiation dose therapy, the dose fraction can be calculated.
Cumulative dose can be calculated by tabulating the radiation dose
measured at each fraction.
To measure absorbed dose, a pre-dose and post-dose reading must
be taken. The pre-dose reading is taken before the radiation
treatment and the post-dose reading is taken after the radiation
treatment. The pre-dose and post-dose threshold voltage readings
are then used to calculate the daily dose fraction that is reported for
each treatment session. The daily fractional dose values are stored
in the Dosimetry Database and are added together to calculate a
cumulative dose.
The dosimeter is powered by the Reader Wand utilizing
electromagnetic energy and does not contain a battery. The
dosimeter derives all power from the Reader-generated
electromagnetic field. The dosimeter modulates the
electromagnetic field to send the digitized threshold voltage
readings back to the Reader.
10
DVS Dose Verification System
The dosimeter is powered telemetrically and measures the
radiation using two MOSFETs. The MOSFETs are hermetically
sealed in a biocompatible glass capsule. The dosimeter is covered
by a polyester surgical mesh for handling, suturing, or fixating the
dosimeter in vivo. The dosimeter is subsequently sterilized with
ethylene oxide. In the tissue, the dosimeter provides a radioopaque image that registers on a dose planning computed
tomography (CT) scan. The measured dose data can be compared
with the prescribed dose plan.
Figure 1 — DVS Dosimeter
Each dosimeter is factory calibrated by correlating to a NISTtraceable ion chamber. The calibration information for each
dosimeter is included in a bar code on pre-printed calibration
labels.
Dosimeters are provided in sterile packages. The expiration date
printed on the dosimeter package is the date when the dosimeter is
no longer considered sterile. Electrical functionality of the
dosimeter is not affected by the sterility expiration.
11
Dose Verification System Overview
2.1 DVS Dosimeter
DVS Dose Verification System
2.2 DVS Reader System
The DVS Reader system is used to take the pre-dose and post-dose
readings from the dosimeter during each treatment session. The
DVS Reader system consists of a Reader Wand and a Base Station
(Figure 2 — DVS Reader). The Base Station includes a touch
screen to view instructions and enter data. The Reader Wand sits in
the cradle of the Base Station and is removed for reading a
patient’s radiation dose. The highlighted end of the Reader Wand
under the LED indicators is the active reading area.
The DVS Reader can be used on a table top or on a pole mounted
to the wall. The pole should be 1.25” in diameter and able to
support 25 pounds.
Figure 2 — DVS Reader
12
DVS Dose Verification System
The DVS Software consists of Plan and Review Software and a
Dosimetry Database. The Plan And Review Software is used to
enter patient treatment information and to access patient data for
viewing and reporting. The Dosimetry Database is a centralized
database to which the Plan and Review Software and the DVS
Reader connect through a local area network (LAN) connection.
All patient information and dosimeter measurements are stored in
the database. A bar code scanner is used to enter calibration
information for the dosimeter. Up to 25 users can simultaneously
access the database.
2.4 Bar Code Scanner
The bar code scanner is used to read the dosimeter serial number
and calibration values from a 2D bar code into the Dosimetry
Database. The 2D bar code is packaged with each dosimeter so it is
easy to scan the calibration values into the DVS system. The bar
code scanner does not require any external power.
2.5 DVS Insertion Tool
The Insertion Tool is an 11 (eleven) gauge needle similar in design
to a bone biopsy needle. It is used for percutaneous and
intraoperative implant procedures and consists of a cannula, trocar,
and plunger.

Quick Start Instructions
4 QUICK START INSTRUCTIONS
This section provides an overview of the workflow for using the
DVS system:
•
Step 1 – Test Dosimeters (recommended)
•
Step 2 – Implant Dosimeter and Record Implant Information
•
Step 3 – Enter Patient Information into the Plan and Review
Software
•
Step 4 – Measure Radiation Pre-Dose and Post-Dose Values
Using the DVS Reader
4.1 Step 1 - Test Dosimeters
Using the DVS Reader, you can test dosimeters before sending
them to surgery. This assures that the dosimeters are working
properly. This step is encouraged but not required.
Important: Do not remove the dosimeters from the package
because this will compromise sterility. Dosimeters can be scanned
through the package. Check the expiration date on the outer
package to ensure sterility.
1. Log in to the DVS Reader.
2. Press Test Dosimeter on the Reader Login screen.
3. Hold the Reader Wand near the dosimeter.

of the following messages:
•
Dosimeter  was found – the dosimeter is
functional.
•
No dosimeter found – the dosimeter could not be located.
Attempt to read again.
•
Dosimeter xxxxxx found. MOSFET is not functional –
there is a problem with the dosimeter. Contact the local
representative for technical support.
5. Press Logout to exit.
4.2 Step 2 – Implant Dosimeters and Record Implant Information
Verify that the DVS Dosimeter and insertion tool package sterility
have not been compromised, are not expired, and that the items
have not been contaminated prior to implantation.
At surgery, specify the implant location of each dosimeter on the
transfer labels provided. The transfer label information aids the
dosimetrist in identifying the dosimeters on a CT scan. For each
dosimeter, retain one transfer label in the surgical records and
return the other to Radiation Oncology.
26
DVS Dose Verification System
Using the Plan and Review Software, enter the patient’s
demographic information and dose planning information. Ensure
that the predicted dose at the dosimeter was obtained by measuring
the point dose 1.3 mm from the end of the capsule opposite the
antenna (Figure 13 — DVS Dosimeter Sensitive Volume). Use a
CT scout film or radiograph to determine dosimeter orientation
within the patient (Figure 14 — CT Scout and Transverse Images).

DVS Dose Verification System
Press Scan Patient to begin the process of reading a
patient’s dose.
6.3 Test a Dosimeter
Dosimeters may be tested prior to implant to assure functionality
or to verify dosimeters that have already been implanted. The
dosimeter may be tested by either entering the dosimeter’s serial
number and scanning using the Reader Wand, or by simply
scanning using the Reader Wand without entering a serial number.
Figure 36 — Test Dosimeter
If there are two or more dosimeters in the read range, then you
need to enter each dosimeter’s serial number one at a time. If you
do not enter a dosimeter’s serial number, then only one dosimeter
is allowed in the read range volume. If there is only one dosimeter
in the read range, make sure the Dosimeter to test field is blank so
the Reader searches for any dosimeter.
•
To read a dosimeter without knowing its serial number,
leave the Dosimeter to test field blank (Figure 36 — Test
Dosimeter ), then hold the dosimeter near the Reader Wand
and press the button on the Reader Wand. The Reader searches
for any available dosimeters within the read range.
