CT IV. generace only x ray tube. the prototype of the first medical CT scanner and is considered the father of computed tomography. CT was introduced into clinical practice into with a scan of a cystic frontal lobe tumor on a patient at Atkinson Morley Hospital in Wimbledon (United Kingdom). After this, CT was immediately welcomed by the medical community andCited by: Computed tomography (CT) is an essential tool in diagnostic imaging for evaluating many clinical conditions.

Actions Shares. This fan beam data is acquired using one detector over the time period it takes for the x-ray tube to rotate from side to side of the fan arc angle [2]. INCREMENT By removing the detectors from the rotating gantry and putting them in a stationary ring around the patient, detectors were able to maintain calibration [4].

Second Generation: Fan Beam, Multiple Detectors Scan times were reduced to approximately 30 s with the use of a fan beam of x-rays and a linear detector array. A translate-rotate scanning motion was still employed; however, a larger rotate increment could be used, which resulted in shorter scan times. The reconstruction algorithms are slightly more compli-cated than those for first-generation. 06/11/ · We describe the data (signal) collected from one exposed detector as a line, or scan line. 4th Generation CT scanners (Rotate-Fixed type) Detectors form a ring that completely surrounds the patient and they do not move. (Stationary detector ring and rotating X-ray tube) The x-ray tube rotates in a circle inside the detector ring, and the x-ray beam is collimated to form a fan beam.

The first CT scanners were solely for head scans and used a rotate/translate system with a single x-ray beam called a pencil beam. The pencil beam used parallel beam geometry. In order to produce such a narrow beam of x-ray photons, the first generation scanner used a pinhole collimator to ensure only a single beam of x-rays was interacting with the patient. Figure 1:First generation scanners.
