THIRD GENERATION:
The third generation scanner is a rotate/rotate system with wide beam geometry (Figure 3). The number of detectors has increased substantially (> 800 detectors) and the angle of fan beam is increased to cover entire patient. It eliminated the need for translational motion.
Fan-Beam CT was introduced in 3rd generation CT. The reason it is called Fan-Beam, is because the beam coming out of the x-ray tube makes the shape of a fan. CT Generations · 1st Generation · 3rd Generation |
