Radiation tomography system and tomography method

摘要

A radiation tomography system includes a radiation source and a radiation detector opposed to the radiation source with a subject between them. The radiation tomography system further includes a scanner that scans a subject by moving the radiation source and radiation detector while rotating them about the subject; a calculator that calculates a control value with which an exposure of a radiation emanating from the radiation source is controlled; and a display on which at least one of calculated control values associated with positions in the direction of rotation of the scanner and control values associated with positions in the direction of a body axis linking the subject's head and the subject's tiptoe is displayed in relation to the respective pieces of positional information on the subject.
