SECTIONAL RADIOGRAPHY DISPLAY METHOD AND APPARATUS

摘要

A sectional radiography display apparatus is provided with a detector driving device (22, 23, 25) for moving a radiation detector (31) on a part of a circumference around a radiation source. The radiation detector is arranged in plural at fixed intervals on the circumference so that the respective incident radioactive ray enters each detector at a right angle thereto, and a plurality of the detectors are joined so that they can be moved simultaneously.
