Computed tomography (CT) produces a digital tomographic image from diagnostic x-rays. The basic principle of CT involves digitizing an image received from a slit scan projection of the patient’s body and then back projecting the image through mathematical algorithms. Although ct scanning is usually performed transversely, digital processing of information can produce sagittal and coronal sections. Because the CT x-ray beam is confined to a slit, much scatter radiation is eliminated from the image. The combination of the transverse sectioning procedure with slit scanning produces an image of significantly better quality than that available with other imaging methonds. Primarily the image differentiates various types of soft tissues (e.g gray matter, white matter, blood, tumor, cerebrospinal fluid, etc) when digital image data manipulation is added, CT provides more diagnostic information than any other ionizing radiation imaging modality.
as with other tomographic modalities, the terms “cut” and “slice” are used in clinical practice. Because these phrases can easily cause distress when overheard by a patient, the radiographer should strive to adhere to the term “section”, avoiding “cut” and “slice”
