2nd Generation: multiple detectors
They had several detectors and the X-ray source emitted radiations in a wide angle. They would obtain multiple scans multiple projections in a single scan.
3rd: Generation: Fan Beam
It had a large array of detectors and would scan in about two seconds. The detector and tube array would rotate around the patient.
4th Generation: A rotating X-ray tube and stationary detector ring
It reduced complexity by reducing motions. Eliminated the translation and rotation motion, had a large fan beam, and had about 4,800 detectors.
5th Generation: Electron Beam CT
It was characterized by a large ring that circled the patient. They would produce electron beams of high energy and capable of scanning in milliseconds. It would produce 17 CT slices every second. ...Download file to see next pagesRead More

Does CT Replace X-ray and if so for What
This is done by means of computers with dedicated imaging equipment. One of the major problem or disadvantage with respect to both X-ray and CT imaging technology is the fact that these techniques use ionizing radiation. Because ionizing radiation can cause tissue damage in a longer run, there is a limit on the total radiation dose per year to which a patient can be subjected.
