Patent ID: 11954785
Assignee: CANON MEDICAL SYSTEMS CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 15:
16. A method for rendering medical images, comprising:
reading, by each of a first GPU and a second GPU, respective data from a data structure stored in virtual memory; and
writing, by each of a first GPU and a second GPU, respective data to the data structure, wherein:
the data structure is configured to be read by both the first GPU and the second GPU;
the data structure is configured such that the first GPU can write to a first sub-space of the data structure and the second GPU can write to a second sub-space of the data structure;
the first sub-space and the second sub-space are independent;
the first GPU is configured to write data relating to a global illumination lighting calculation to the first sub-space, the written data comprising irradiance data;
the second GPU is configured to read the irradiance data and to render at least one image based on the irradiance data, 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.
