End-to-End Quality Assurance of Stereotactic Radiation Therapy Using an Anthropomorphic Head Phantom

“…All gel dosimeters were scanned using a Vista Optical CT Scanner (ModusQA, London, ON) pre-irradiation, and 30 mins post-irradiation. Analysis of the gel dosimeter data was performed using 3D Slicer the Gel Dosimetry Analysis slicelet [9].…”

“…Across all film and gel fiducial based registrations, the average root mean square error (RMSE) between coincident fiducial points was < 1 mm. Film and gel dosimeters were all calibrated under standard conditions [9] so that an absolute dosimetric comparison could be made (no dose scaling was performed). Gel dosimeters were handled according to the protocols described in Olding and Schreiner (2011) [10].…”

Post-processing techniques using 3D Slicer for T1-weighted MRI analysis of radiochromic gel dosimeters

“…After acquisition of the pre-irradiation and post-irradiation MR images, the relative volumetric dose distributions quantified in the gels were compared to calculated doses from the Monaco TPS using 3D Slicer (version 4.6.2) [19,20]. 3D Slicer was an open source software platform that could be used for a wide variety of applications and has been validated for TPS plan comparisons using gamma analysis [21][22][23]. The 3D Slicer workflow has been described previously and is summarized below: using the SlicerRT extension, import and load DICOM files of the TPS dose, structures, pre-irradiation MRI, and post-irradiation MRI); subtract the MRI prescan from the MRI postscan; transform the subtracted MRI volume to match TPS plan volume using the adapted plan fusion coordinates; post-process as needed and scale to relative dose; assess 3D gamma analysis using the Dose Comparison module [5].…”
