Medical imaging technology using X-rays and Computed Tomography (CT) creates images of different parts of the body by exploiting the varying absorption properties of materials and tissues. CT generates 3D graphics by rotating X-ray sources around the body and comparing images taken at different locations and times. The core components of a scanner are the X-ray generator and detector, which can be film or specialized image sensors. Additionally, the equipment must provide patient accommodation facilities and means for medical staff to operate and control the device correctly.
