% LUTHMANN QATOOLFOR HDR AND LDR BRACHYTHERAPY Developed by Robert Luthmann, PhD Atlantic Beach, FL The Luthmann QA Tool in position for advancement of the HDR source. • for hdr quality assurance 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. Provide excellent hard copy documentation for QA files. • for LDR quality AssuRANcE Tests of ribbon isotopes Upon receipt of LDR sources, the following quality assurance tests are useful to verify the integrity of your LDR sources. • Confirm the relative uniformity of sources. • Verify custom loading of ribbons. • Visual verification of source spacing. • Provide excellent hard copy documentation for QA files. STANDARD IMAGING.

Purpose: The purpose of this test is to: One. 1. Determine the distance from the HDR unit to the most distal position of the source. Frequency: Test Two is performed on a daily basis Brachytherapy 2. Verify accuracy of the stepping motor in positioning the source at various dwell positions in before the treatment. each channel. 3. Verify the integrity of each of the localization dummies used clinically for HDR source position localization. For LDR Quality Assurance Tests of Ribbon Iso Upon receipt of LDR sources, the following quality assurance Frequency: Test One is performed at the time of...
