MIMvista highlighted its Serial Exam Review, MIM for Radiation Oncology, MIMneuro and Storage Server offerings at this year’s RSNA conference in Chicago.
MIMvista’s Serial Exam Review allows for the tracking of abnormalities between time points from any number of exams from multiple modalities (CT, MR, PT, 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 can also be aligned with greater accuracy across time points utilizing the same deformation from the CT. The registration method can also 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, etc.) 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 re-contouring for adaptive therapy and gated studies as well as Atlas-based segmentation, which automatically generates entire structure sets for initial contour generation.
Adaptive re-contouring deforms contours from an original planning CT to a new planning CT, making true adaptive radiation therapy practical. Entire gated CT studies can be contoured by deforming contours from a single phase to match the anatomy on all phases, according to the company.
Deformable co-registration corrects for non-rigid differences in alignment allowing PET/CTs to be aligned with greater accuracy to the planning CT, even when the PET/CT was not obtained in treatment position.
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, MIMvista said.
The company also demonstrated the MIM Storage Server, which provides access to image date through an integrated archive solution.
MIM Storage Server enables rapid archive searching and data transfer with automated study routing and image retrieval. It is capable of storing radiation therapy specific formats including RT Dose, Plan and Structs. Scalable security options are provided using LDAP/Active Directory and storage is easily expanded using readily available hardware.
