The Computed Tomography Market deals with the development, manufacture and distribution of computerized axial tomography (or CAT) scanning machines. A CT scan involves the usage of computer processes to see inside an object or the human body without cutting it up. Several X-ray images are derived from numerous angles to form tomographic images of a particular area within the subject or object.
