Overview

Create. Confidence. Clarity.

With imaging at the heart of everything we simulate, plan, calculate and treat in radiation therapy, it is critical that the routine QA and validation of techniques and devices involving imaging is undertaken regularly and rigorously. This is why ImSimQA exists.

Why ImSimQA?

ImSimQA is the only dedicated, independent system for the testing of clinical imaging techniques such as deformable image registration and other processes, found in radiotherapy planning and onboard treatment imagers such as CBCT-IGRT, MVCT-IGRT and the new MR linacs. Imaging algorithms found in multi-modality planning, adaptive re-positioning and dose re-calculation, ultra-precise image registration in SABR, SBRT, AI and auto-contouring and image motion sequences for 4D respiratory gating, all require accuracy, and therefore considered testing.

ImSimQA CREATES clinically relevant test data using virtual phantoms, and a NEW extensive set of clinical image test cases covering a range of modern clinical techniques.

ImSimQA provides CONFIDENCE and CLARITY through years of experience of development and working with professional organisations such as the AAPM, in providing test protocol workflows, and quantifiable tests that analyse and report results.

TG-132 recommended, fully compliant testing

The AAPM TG-132 report stresses the need not only for initial validation but for ongoing QA testing of clinical imaging techniques and imaging devices used in radiation therapy. Differences and changes in software, imaging protocols, contrast imaging, set-up techniques, all require rigorous testing in addition to the all-important understanding of limitations and accuracy of imaging, planning and treatment systems when introduced into a clinic. To this end, a few imaging datasets are provided with this TG-132 report (generated by ImSimQA, donated by OSL) but this is a bare minimum and only provides a starter set for a regimen of ongoing QA and validation. The ImSimQA application builds on the report, providing all the recommended analysis tests, and importantly adds an infinite array of test data through a library of editable, customisable virtual phantoms, plus a wide range of real clinical DICOM cases that can also be extensively edited. Users can easily import and export DICOM images, deformation vector fields, creating test protocols specific to local clinical practices and equipment.
