Abstract:
For visualization in medical imaging, a hybrid volume ( 22 ) and surface ( 24 ) renderer ( 16 ) uses unified ray tracing. Rather than separately rasterizing the surface ( 24 ) and ray tracing the volume ( 22 ), a same ray or set of rays is used for both the volume ( 22 ) and the surface ( 24 ). Various effects may be modeled by determining ( 34 ) the intersection of the ray with the surface ( 24 ) or surfaces ( 24 ) and integrating ( 36 ) the volume ( 22 ) data in parallel. For medical imaging ( 38 ), more complex effects, interactive rendering, and/or real-time rendering may be provided by altering the integration for ray tracing based on the detected intersections.

Claim (Index 19):
A non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for visualization in medical imaging, the storage medium comprising instructions for:\n acquiring from a medical scanner a sequence of voxels representing a patient volume over time; ray casting through the voxels for each time; integrating voxels along rays based on the ray casting for each of the times; traversing an acceleration structure using the same rays in parallel with the integrating along the rays, the traversing identifying intersections of the rays with a surface for each of the times, the identified intersections used to alter the integrating; and generating a sequence of rendered images from the integrated voxels, pixel values of the rendered images based on the intersections.
