A 3d Us Guidance System For Permanent Breast Seed Implantation: Development And Validation, Justin Michael
Electronic Thesis and Dissertation Repository
Permanent breast seed implantation (PBSI) is a promising breast radiotherapy technique that suffers from operator dependence. We propose and have developed an intraoperative 3D ultrasound (US) guidance system for PBSI.
A tracking arm mounted to a 3D US scanner registers a needle template to the image. Images were validated for linear and volumetric accuracy, and image quality in a volunteer. The tracking arm was calibrated, and the 3D image registered to the scanner. Tracked and imaged needle positions were compared to assess accuracy and a patient-specific phantom procedure guided with the system.
Median/mean linear and volumetric error was ±1.1% and …
