Method and system for performing real-time volume rendering to provide enhanced visualization of ultrasound images at a head mounted display

摘要

A processor receives sensor feedback indicating a focal point of an HMD user. The processor casts rays through an image volume based on the sensor feedback. Each of the rays is associated with a pixel of a rendered image. The rendered image has a first plurality of pixels associated with the rays and a second plurality of unassociated pixels. The rays comprise a first portion cast at or near the focal point and a second portion that is cast farther away from the focal point. A first spacing between rays of the first portion is less than a second spacing between rays of the second portion. The processor determines color values corresponding with each of the first plurality of pixels associated with the rays. The processor determines color values corresponding with each of the second plurality of unassociated pixels of the rendered image. The HMD displays the rendered image.
