Virtual Phantom Library & Editing

Oncology Systems Limited's ImSimQA provides a toolkit of 15 virtual phantoms that can be extensively edited and transformed, before being converted to DICOM CT, MR & PET simulated images. With the ability to add noise, change density, change slice spacing and re-orientate, the phantom DICOM images are then exported to the test application, minimising the use of the real scanner, and increasing the efficiency of testing. Real DICOM images can also be imported into ImSimQA for editing, without having to continually re-scan.

New for 2014 - Additional phantoms

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.
