Henry is an image based toolkit for Medical Physicists in Radiotherapy.
Image sources range from Dicom Dose Cubes, Planning System dose planes, EPID, CT, and film. Non-image data such as Dicom Plan files, Dicom Structure sets can be displayed and used to estimate dose delivery (either directly from the plan, or from back projection of EPID data) so that this can be compared with Dose Cubes from the planning system for plan confirmation – the picture below is from a combination of 9 and 12MeV electron beams computed with Monte Carlo by the planning system XiO® (Solid lines), compared with an estimate based on a pencil beam generated by Henry (Dashed Lines).
Examples of Linac QA, include using EPID imaging to confirm the picket fence test patterns from the upper and lower jaws for checking calibration of jaw movement. Star shot analysis from concentricity, and Winston-Lutz testing of alignment (Below is an Elekta® HIS format file, where the edge detection has found the field boundry and target bearing).
An example of Treatment delivery QA using the EPID image capture for a Siemens® mARC™ being back projected into a patient data set and compared to the Dose Cube data generated from Elekta®’s Monaco™ planning system is shown below (Solid line – Planning system, Dashed line – EPID back projection estimation):
