Time of Flight. The simplest way to think about âtime of flightâ laser scanning is to look approach it as nothing more than a laser range finder. I think we all understand how a laser range finder works. It basically measures a distance by shooting a laser beam out to an object and measuring how long it takes that laser beam to bounce back.
Pr. Mirjan M. Nadrljanski et al. Computed tomography (CT) scanning, also known as computerized axial tomography (CAT) scanning, is a diagnostic imaging procedure that uses X-rays in order to present cross-sectional images (slices) of the body.n the specific case of the CT, the emitter of X-rays rotates around the patient and the detector, placed in diametrically opposite side, picks up the image of a body section (beam and detector move in synchrony). Unlike X-ray radiography, the detectors of the CT scanner does not produce an image.
