Extension Description

Igyne is an open source software for MR-Guided Interstitial Gynecologic Brachytherapy. It enables on-time processing of the intra-operative MRI data via a DICOM connection to the scanner followed by a multi-stage registration of CAD models of the template and the obturator to the patient images. This allows the virtual placement of interstitial needles during the intervention to assist the physician positioning decision.Software features include:

• Loading of Applicator CAD models and MR images
• Initial registration of CAD model of the Template to MR images
• Registration Refinement
• Visualization of Registration
• Needle Selection and Display of Virtual Needles relative to Applicator CAD models and Tumor Segmentation

Modules

• Plastimatch Automatic deformable image registration
• Plastimatch DICOM-RT import
• Plastimatch DICOM-RT export
• Plastimatch Dose Comparison
• Plastimatch Dose Volume Histogram
• Plastimatch LANDWARP Landmark
• Plastimatch Synthetic Image Generation
• Plastimatch Threshold in a box
• Plastimatch XFORMWARP
