SIS Software Version 3.6.0

SIS Software Version 3.6.0 is an advanced medical imaging application designed to aid neurosurgical planning by providing enhanced 3D visualization of brain structures, particularly the subthalamic nuclei. It utilizes machine learning, sophisticated image processing for MRI and CT scans, and improved image fusion and registration methodologies, including handling for CT gantry tilt, to generate patient-specific anatomical models for stereotactic procedures.

SIS Software Version 3.6.0 is a medical imaging application designed for medical professionals, including surgeons, neurologists, and radiologists, to assist in neurosurgical procedures. Its core capabilities encompass the viewing, presentation, and documentation of medical images, featuring modules for image processing, image fusion, and intraoperative functional planning. The software generates 3D outputs that are compatible with stereotactic image-guided surgery systems and other visualization tools, with a specific indication to aid in the visualization of the subthalamic nuclei (STN), thereby supplementing standard clinical methods by offering enhanced visual information. The technology underpinning SIS Software leverages machine learning and advanced image processing algorithms to create patient-specific 3D anatomical models of brain structures from MRI and CT scans. Version 3.6.0 introduces significant enhancements, including a more comprehensive MR to post-operation CT registration methodology that utilizes tools like ANTS and ELASTIX for both linear and non-linear registration. It also features improved image processing techniques to handle CT images acquired with gantry tilt. Performance validation confirmed these modifications maintain accurate image registration and object segmentation, with results comparable to its predecessor. Additionally, this version includes an updated web user interface with more administrative options and audit logging functionalities.
