Virtual Trainer for Ultrasound-guided Renal Biopsy (1090-003972)
CE Hours: 0.25 Cost: $0.00
Description:
The goal of the project is to build a virtual trainer that is intended to train radiologists, nephrologists, and interventional radiologists to improve procedural skill competence in ultrasound-guided renal biopsy. The virtual simulator provides several advantages including acceleration of the training of ultrasound-guided renal biopsy in a risk-free environment to improve the safety of kidney biopsy and ensuring that the biopsy procedure yields high quality specimen. The simulator includes three major areas of innovation 1) Utilization of anonymized real patient images: For trainees to grasp the complexity and challenge of interpreting kidney anatomy on ultrasound, the simulator will use high quality 3D kidney ultrasound images from real patients. 2) Incorporation high fidelity needle-tissue interaction modeling algorithms: The simulator incorporates a haptic device for needle insertion to provide realistic simulation of the force profile that a clinician would experience during the insertion of a needle through the various tissue layers surrounding the kidney. The high fidelity algorithm models and simulates the deformations of various tissue layers that are coupled with the needle motion, estimates the frictional forces between the walls of the needle with the tissue surrounding it and estimates puncture forces given the shape of the needle tip, and 3) Construction of an affordable and easily extendable simulator using off-the-shelf hardware components and powerful open source visualization and interactive simulation libraries. Three aspects of the simulator lend to its extendable nature (a) modular framework employed using 3D Slicer and iMSTK (b) generic needle-tissue interaction algorithms suitable for extension to other biopsies, and (c) generic hardware design. The technology built in this project has the potential to be used not only in renal biopsy but other clinical procedures such as liver biopsy (which has a higher volume of patients and therefore broader appeal to providers according to expert and user interviews), transjugular and laparoscopic renal biopsy (these procedures represent reliable alternatives to conventional percutaneous biopsy in patients at high risk of bleeding).
