Assignee: CANON MEDICAL SYSTEMS CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 16:
17. A medical image processing apparatus for rendering medical images comprising a multi-kernel GPU configured to read from and write to a data structure stored in virtual memory, wherein:
the data structure is configured to be read by a first kernel of the GPU and a second kernel of the GPU;
the data structure is configured such that the first kernel can write to a first sub-space of the data structure and the second kernel can write to a second sub-space of the data structure;
the first sub-space and the second sub-space are independent;
the first kernel is configured to write data relating a global illumination lighting calculation to the first sub-space, the written data comprising irradiance data;
the second kernel is configured to read the irradiance data and to render at least one image based on the irradiance data, and
and the first GPU is configured to perform the pre-processing at a first frame rate, and the second GPU is configured to perform the rendering at a second, faster frame rate.
