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

Contraindications

• 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 three-

prong 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

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 alcohol-

based 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

• 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 build-

up and minimizes potential for mechanical damage.

Notes

The dosimeter is factory calibrated and does not require calibration

during use.

Welcome

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.

DVS Dose Verification System

2.1 DVS Dosimeter

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 radio-

opaque 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 NIST-

traceable 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.

Dose Verification System Overview

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

DVS Dose Verification System

2.3 DVS Software

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.

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.

Quick Start Instructions

DVS Dose Verification System

4. Press and release the button on the Reader Wand to scan the

dosimeter. Below the status bar, the DVS Reader displays one

of the following messages:

• Dosimeter <number> 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.

DVS Dose Verification System

4.3 Step 3 – Enter Patient Information Into the Plan and Review

Software

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).

Dosimeter results are displayed in a tab labeled with the dosimeter

location.

The first chart is the Relative Dose Chart. This shows the

difference between each measured dose and its predicted dose as a

percentage. The value shown for each bar is the measured dose

relative to the predicted dose.

The second chart is the Absolute Dose Chart. This shows the

measured doses (in cGy) as gold bars, and the predicted doses as

blue lines. Each plan is shown as a separate blue line.

In the charts, the brown bars identify measurements where either a

port film was taken or notes were entered by the user.

For each of the charts, the mouse can be positioned over a bar to

show more information about the measurement:

• The value of the measurement

• The date of the measurement

• Who made the measurement

• The monitor units from port films that were taken

• Any notes selected during the measurement process

No bars are shown for skipped fractions or fractions where a

dosimeter value could not be read. Positioning the mouse over

these empty spaces will show if it was a skipped fraction or a

measurement error.

The Statistics Table shows summary statistics for each of the

patient’s plans. The columns are as follows:

• Plan name – The name of the plan

• Fractions planned – The number of fractions in the plan

• Fractions used – The number of dose fractions administered

so far

• Total predicted dose (cGy) – The expected dose administered

for the number of fractions displayed in the Fractions used

column
