A computed tomography scan (usually abbreviated to CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to … WebIndustrial Computed Tomography with ZEISS METROTOM. With a industrial computed tomography system from ZEISS, you can successfully perform measuring and inspection jobs yourself with only one X-ray scan. The standard acceptance test, the precision engineering and the sophisticated calibration process ensure the traceability of the system.
