MIMvista’s VoxAlign Deformation Engine allows for Atlas-based Segmentation and Re-contouring for Adaptive Therapy  

MIMvista (Booth 2015) is highlighting its Serial Exam Review, MIM for Radiation Oncology, and MIMneuro package at RSNA 2008.

MIMvista’s Serial Exam Review allows for the tracking of abnormalities between time points from any number of exams from multiple modalities (CT, MR, PET, SPECT), which can be automatically linked or fused for easy comparison. Triangulation of the fused or linked exams allows corresponding abnormalities to be tracked between time points. Non-rigid differences between the serial exams can be overcome using the CT to CT deformable registration provided by the VoxAlign Deformation Engine.

PET exams co-registered to the CT also can be aligned with greater accuracy across time points utilizing the same deformation from the CT. This registration method can be used to segment the tumors on a new CT exam through a deformable re-contouring technique. Tumors on PET exams can be segmented accurately in seconds using PET Edge. Tumor statistics (volume, SUVmax, SUVmean, RECIST, WHO) and screen captures can be added to customizable reports or saved to a MIMviewer DICOM CD for referring physician review. All contours can be saved as DICOM RT Structs and sent to radiation therapy planning systems.

MIM for Radiation Oncology features automatic deformable contouring, using the VoxAlign Deformation Engine which allows for Atlas-based segmentation and re-contouring for adaptive therapy and gated studies. Atlas-based segmentation automatically generates entire structure sets—including target volumes, reducing time for initial contour generation.

MIMvista’s MIMneuro package now includes an automated workflow for epilepsy analysis performing ictal-interictal SPECT subtractions and MR co-registration in a few steps, within one diagnostic reading station. The automated system highlights significant foci by cluster analysis providing radiologists and their referring physicians with a clear picture of the epileptic focus in less than five minutes, the company says.
