Upper limit of tube performance. It is also important to compare the length of protocols that the tube will allow and how quickly they can be repeated. Filtration Compensating filters are used to shape the x-ray beam. They reduce the radiation dose to the patient and help to minimize image artifact. As mentioned in Chapter 1, radiation emitted by CT x-ray tubes is polychromatic. Filtering the x-ray beam helps to reduce the range of x-ray energies that reach the patient by removing the long-wavelength (or “soft”) x-rays.

BOX 25 Detector array FIGURE 27 A third-generation scanner design is one in which the x-ray tube is placed opposite the detector array. Both the tube and the detector move in a circle within the gantry. Key C ncept The configuration of the x-ray tube to the detector determines scanner generation. The next advance in CT technology brought the thirdgeneration design. This design consists of a detector array and an x-ray tube that produces a fan-shaped beam that covered the entire field of view and a detector array (Fig.

Low scatter acceptance is desirable. Simple geometric principles affect scatter acceptance. with this fan beam. A detector array was also incorporated in the second-generation design. Although scan times were shorter than that of the original design, they were still very long. This type of design is also no longer used.
