ImSimQA™ software is unique. ImSimQA was developed due to the limitations of hard phantoms for testing modern radiation therapy and imaging software systems.

With the growth of advanced technologies such as deformable image registration, atlas-based auto contouring, adaptive RT, 4D planning and gating, it is clear that innovative tools are required for validation and QA.

ImSimQA provides extensive tools for generating infinite test image data, from any imported DICOM-3 images, and from virtual phantoms. Transformations, deformations and DICOM editing can be applied, and quantifiable analyses can be run on the results re-imported from clinical systems.

ImSimQA is TG-132 ready.

Clinical applications that can be tested using ImSimQA

  • Deformable and rigid image registration
  • Auto contouring algorithms
  • Adaptive RT
  • 4D imaging and planning
  • 3D margin growing, DRR accuracy, structure bifurcations

Work with UF Health Cancer Center - Orlando Health has led to the development of an additional library of 10 original and deformed synthetic head and neck phantoms created where the deformed dataset is based on actual anatomical changes seen during the radiotherapy treatment course. From these a ground truth deformable vector field (DVF) was created for each phantom. This allows the phantoms to be used to assess the accuracy and precision of the DIR algorithm in any available system, with clinically relevant data (Pukala et al, 2013). The 10 phantoms and ground truth DVFs are available for all ImSimQA current and new customers who have the ImSimQAdform and ImSimQAcontour modules.
