Principlesits capability to image minute differences in X-ray attenuation coefficients. The reasons for this are, first, CT only takes cross section slices and reconstructs them into two-dimensional images for display so that redundant shadows do not overlap. Second, as it utilizes one or more thin X-ray beam

Developments in CT technology have reduced the scanning time, but those aspects cited above still require these procedures to be used as economically as possible. Consequently, an appo

The International Commission on Radiological Protection (ICRP 1977) went on to stress “justification” of the procedure’s dosage related to the benefits, costs, and risks that are a consequence of CT examination, and that minimum X-ray exposure doses should be used when undertaking tomo

Orientation and Interpretation of CT Imagessent status of the illness are investigated; diagnosis of the disease closest to the given history is then made. In interpreting the CT image, the image is compared with that of the normal anatomy and examined for abnormality in size or shape of organs or tissue. ... Therefore, for interpretation of

In case a highly radiosensitive healthy tissue exists close to the tumor, it is essential to know its position accurately in order to minimize radiation injury.

Difference Between CT Images for Radiation Therapy and Those for Diagnostic Purposesly, depending on whether the patient is in a standing or lying position (Takahashi 1969; de Winter 1979; Geise and McCullough 1977; McCullough 1978), and even in the lying position, it is necessary to distinguish between supine or prone.
