Accurate positioning of the HDR 192IR- source is essential
for proper treatment. The Luthmann Source Positioning
QA Tool has been developed to perform required quality
assurance checks for your HDR unit.
• Determine the distance to the most distal position.
• Verify the accuracy of HDR unit’s stepping motor in
positioning the source for up to 18 channels at one time.
• Perform quick, daily constancy checks of source
positioning by the HDR unit.
• Verify accuracy of the stepping motor in positioning
the source at dwell positions in each channel.
• Eliminate the need for expensive and cumbersome
video camera and monitor.
• ProvideexcellenthardcopydocumentationforQAfiles.

Test OnePerformed Upon System Acceptance and After Source Changes
Purpose: The purpose of this test is to:
1. Determine the distance from the HDR unit to the most distal position of the source.
2. Verify accuracy of the stepping motor in positioning the source at various dwell positions in each channel.
3. Verify the integrity of each of the localization dummies used clinically for HDR source position localization.
Frequency: Test One is performed at the time of machine acceptance, after source change and at specific intervals as a QA check to verify the integrity of each localization dummy.
Test Two, Periodic Quality Assurance Tests
Purpose: The purpose of this test is to act as a constancy check for the three parameters in Test One.
Frequency: Test Two is performed on a daily basis before the HDR unit is used clinically for patient treatment.
The Luthmann Source Positioning QA Tool provides for an auto-radiograph of the sources and visual inspection of the spacing of ribbon seeds. The ribbons with multiple seeds are placed in the channels for the autoradiograph. Steel rulers placed along the outer two channels can be used for visual verification.
