Overview
SliceTracker is a 3D Slicer extension designed to support the workflow of the in-bore MRI-guided targeted prostate biopsy (MRgBx) (see references below for clinical context). SliceTracker was developed and tested to support transperineal MRgBx procedure in the Advanced Multimodality Image Guided Operating (AMIGO) at the Brigham and Women's Hospital, Boston. Its applicability to other types of procedures has not been evaluated.
Capabilities of SliceTracker include:
- automatic processing of the patient DICOM images
- planning of the procedure (biopsy target localization)
- calibration of the intra-procedural image frame of reference with the transperineal biopsy template
- automated segmentation of the prostate gland
- deformable intensity-based registration to support
- re-identification of the pre-procedurally defined targets in the intra-procedural images
- automated, continuous tracking of the biopsy targets during the course of the procedure
- structured collection of the relevant data during the course of the procedure (images, results of segmentation and registration, target tracking)
- visualization of the intra-procedural images and support of specialized hanging protocols to facilitate needle tracking, biopsy template and calibration device visualization, assessment of the image registration results, etc.
