Abstract: A medical image processing apparatus for rendering medical images includes a first GPU and a second GPU, each configured to read from and write to a data structure stored in virtual memory. The data structure is configured to be read by both the first GPU and the second GPU and 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 pre-processing for rendering to the first sub-space and the second GPU is configured to read the written data and to render at least one image based on the written data.

Abstract: A medical image processing apparatus comprises processing circuitry configured to: receive a selection of a preset transfer function that sets colors used in volume rendering, wherein the preset transfer function is selected for use in rendering at least one target material; determine a first transfer function relating to transmission or extinction color, wherein the determining of the first transfer function is based on the preset transfer function; generate first rendering data based on transmission or extinction color by using the first transfer function; and determine a second transfer function relating to reflection color, wherein the determining of the second transfer function is based on the first rendering data, wherein the first transfer function and second transfer function are for use in global illumination rendering.

Abstract: A medical image display apparatus comprises processing circuitry configured to: receive a plurality of frames each comprising respective medical image data; specify an order of priority for the plurality of frames; select regions of medical image data from more than one of the frames of the plurality of frames based on the order of priority; and generate combined image data by combining the selected regions of medical image data, such that different regions of the combined image data comprise medical image data from different ones of the plurality of frames.

Abstract: A medical image processing apparatus comprises processing circuitry configured to: obtain medical image data comprising or representative of image data values and segmentation values for pixels or voxels of a volume; specify a sampling point within the volume; select a relevant pixel or voxel for the sampling point from a set of pixels or voxels neighboring the sampling point, wherein the selecting is based on a difference of an interpolated image data value at the sampling point and an image data value for each of the neighboring pixels or voxels and a distance between the sampling point and each of the neighboring pixels or voxels; and determine a segmentation value for the sampling point based on a segmentation value at a position of the selected relevant pixel or voxel.
