Abstract
A medical system comprising a selection unit configured to select at least one of layers in a three-dimensional tomographic image of a retina, and a generation unit configured to generate an opacity function indicating an opacity of each of a plurality of voxels constituting the selected layer, based on a frequency distribution of luminance values of the plurality of voxels.
Claims20
1-13. (canceled)
A processing apparatus comprising:
- a selection unit configured to select a display target in a retina;
- and
- a generation unit configured to generate an opacity function indicating an opacity of a plurality of voxels constituting a region corresponding to the selected display target in a three-dimensional tomographic image of the retina, based on the selected display target and a frequency distribution of luminance values of the plurality of voxels.
The apparatus according to claim 1, wherein the selection unit selects layers between a lower end of a nerve fiber layer and a retinal pigment epithelium as the region when a white spot is selected as the display target, and
- wherein the generation unit generates, based on a frequency distribution of luminance values of the plurality of voxels constituting the selected layers, an opacity function that indicates higher opacities for voxels, which have luminance values higher than a predetermined value, than for other voxels among the plurality of voxels.
A processing method comprising:
- selecting a display target in a retina;
- and
- generating an opacity function indicating an opacity of a plurality of voxels constituting a region corresponding to the selected display target in a three-dimensional tomographic image of the retina, based on the selected display target and a frequency distribution of luminance values of the plurality of voxels.
