Abstract
A medical processing apparatus comprises processing circuitry configured to: receive an image data set for rendering; for each of a plurality of a pixels or voxels in the image data set: set a region of interest around the pixel or voxel; determine a maximum data value and a minimum data value for pixels or voxels in the region of interest; and designate the pixel or voxel as visible or as non-visible based on the maximum data value and the minimum data value for the region of interest; and perform a rendering process using the pixels or voxels of the image data set that designated as visible.

A medical processing apparatus comprising processing circuitry configured to:
- receive an image data set for rendering;
- for each of a plurality of a pixels or voxels in the image data set:
- set a region of interest around the pixel or voxel, the region of interest comprising pixels or voxels that could be combined with the pixel or voxel during interpolation;
- determine a maximum data value and a minimum data value for pixels or voxels in the region of interest, thereby determining a range of possible interpolated data values;
- and
- designate the pixel or voxel as visible or as non-visible based on whether any of the possible interpolated values is visible;
- and
- perform a rendering process using the pixels or voxels of the image data set that are designated as visible.
