摘要： A γ-ray signal processing section 60′ determines a detection time of a γ ray based on a γ-ray detection signal outputted from a semiconductor radiation detector for detecting the γ ray, and determines the energy of the γ ray. Then, a time correction circuit 70 obtains, based on the energy of the γ ray, a detection value of the detection time that corresponds to the energy of the γ ray from a time correction table indicating the relationship between the energy of the γ ray and the correction value of the detection time of the γ ray, and corrects the detection time according to the obtained correction value of the detection time. Coincidence counting is performed on the γ ray in a coincidence counting circuit 80 based on the corrected detection time.

摘要： An X-ray CT image of a low spatial resolution image is acquired by employing a PET-X-ray CT examination apparatus. Also, a PET image is acquired by employing the PET-X-ray CT examination apparatus. Furthermore, an X-ray CT image of a high spatial resolution image is acquired by employing another X-ray CT examination apparatus. Then, the X-ray CT image equal to the low spatial resolution image is corrected by employing the X-ray CT image, so that an X-ray CT image equal to a high spatial resolution image is obtained. Since a positional relationship of the resulting X-ray CT image with respect to the PET image can be grasped, this PET image can be simply synthesized with the X-ray CT image.

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.
