Study Notes
Computed Tomography (CT) Basics
- The primary purpose of computed tomography (CT) is to produce detailed cross-sectional images of the body.
Advantages of CT Images
- A significant advantage of CT images compared to conventional radiographs is their ability to provide detailed, high-contrast images of soft tissues and bones.
History of CT Development
- The theoretical basis of CT was developed by Godfrey Hounsfield and Allan McLeod Cormack.
Types of CT Scanners
- A third-generation CT scanner is capable of acquiring and reconstructing the image of a thin cross-section based on measurements of attenuation.
Milestones in CT Development
- The first commercial CT scanner was developed in 1972.
