摘要： In a radiological inspection apparatus, a subject lying on a bed is located in the center of an imaging device. A large number of radiological detectors are arranged around the subject. The radiological detectors are arranged in multiple stages in a direction normal to the body axis of the subject. The radiological detectors are sequentially arranged in three stages in a direction away from the subject. A large number of combinations each of the three radiological detectors are installed like a ring so as to surround the subject. If circuits in the radiological detectors detect a plurality of signals considered to be coincident, the system selects one of the radiological detectors which is closer to the subject depending on the energy of radiation.
