Ct image size
WebA CT scan is a diagnostic imaging exam that uses X-ray technology to produce images of the inside of the body. A CT scan can show detailed images of any part of the body, including the bones, muscles, organs and blood vessels. CT scans can also be used for fluid or tissue biopsies, or as part of preparation for surgery or treatment.

WebMay 12, 2024 · Despite these successes, DRP has its limitations. Typical micro-CT image cross section does not exceed 4000 voxels in each direction; thus, the size of the investigated core samples scales linearly with the resolution. It follows that the finer the resolution of the image, the smaller the physical size of the sample.
