Принадлежит: Leland Stanford Junior University

Computational methods are used to create cardiovascular simulations having desired hemodynamic features. Cardiovascular modeling methods produce descriptions of blood flow and pressure in the heart and vascular networks. Numerical methods optimize and solve nonlinear equations to find parameter values that result in desired hemodynamic characteristics including related flow and pressure at various locations in the cardiovascular system, movements of soft tissues, and changes for different physiological states. The modeling methods employ simplified models to approximate the behavior of more complex models with the goal of to reducing computational expense. The user describes the desired features of the final cardiovascular simulation and provides minimal input, and the system automates the search for the final patient-specific cardiovascular model.

A system and method for improving a surgeon's vision by overlaying augmented reality information onto a video image of the surgical site. A high definition video camera sends a video image in real time. Prior to the surgery, a pre-operative image is created from MRI, x-ray, ultrasound, or other method of diagnosis using imaging technology. The pre-operative image is stored within the computer. The computer processes the pre-operative image to decipher organs, anatomical geometries, vessels, tissue planes, orientation, and other structures. As the surgeon performs the surgery, the AR controller augments the real time video image with the processed pre-operative image and displays the augmented image on an interface to provide further guidance to the surgeon during the surgical procedure.
