Endoscopic ultrasonography simulation

摘要

A method and a system to simulate ultrasound images and hence for simulating the evaluation of a subject with such images as a diagnostic tool. For the purpose of simulating ultrasound images, these images may be considered to be planar slices of a given geometry. These slices are generated from the surface geometry of the portion of the subject which would receive the ultrasound waves if the ultrasound diagnostic procedure was actually be performed. Simulating such ultrasound images may therefore be performed by determining such images from surface models, and then rendering those ultrasound images at the desired position. The rendering of such simulated ultrasound images also optionally and preferably includes the simulation of the "grainy" quality of such images.
