Integrated navigation and control software system for MRI-guided robotic prostate interventions
A software system to provide intuitive navigation for MRI-guided robotic transperineal prostate therapy is presented. In the system, the robot control unit, the MRI scanner, and the open-source navigation software are connected together via Ethernet to exchange commands, coordinates, and images using an open network communication protocol, OpenIGTLink. The system has six states called "workphas...
متن کاملA networked modular hardware and software system for MRI-guided robotic prostate interventions
Magnetic resonance imaging (MRI) provides high resolution multi-parametric imaging, large soft tissue contrast, and interactive image updates making it an ideal modality for diagnosing prostate cancer and guiding surgical tools. Despite a substantial armamentarium of apparatuses and systems has been developed to assist surgical diagnosis and therapy for MRI-guided procedures over last decade, t...
متن کاملAccuracy validation for MRI-guided robotic prostate biopsy.
We report a quantitative evaluation of the clinical accuracy of a MRI-guided robotic prostate biopsy system that has been in use for over five years at the U.S. National Cancer Institute. A two-step rigid volume registration using mutual information between the pre and post needle insertion images was performed. Contour overlays of the prostate before and after registration were used to validat...
متن کاملRobotic Assistant for Transperineal Prostate Interventions in 3T Closed MRI
Numerous studies have demonstrated the efficacy of image-guided needle-based therapy and biopsy in the management of prostate cancer. The accuracy of traditional prostate interventions performed using transrectal ultrasound (TRUS) is limited by image fidelity, needle template guides, needle deflection and tissue deformation. Magnetic Resonance Imaging (MRI) is an ideal modality for guiding and ...
متن کاملSoftware / Hardware Integration for MRI-guided Robotic Prostate Intervention using Open IGT Link
We propose a software and hardware integration strategy for MRI-guided robotic prostate intervention using an open network communication protocol. In the MRI-guided robotic intervention, the robot, navigation software and MRI scanner communicate one to another via Ethernet to exchange various data e.g. robot position, commands and MR images. Since the components were developed in the different ...
