摘要： A radiological imaging apparatus of the present invention includes an X-ray source for emitting an X-ray, a γ-ray detecting section for outputting a detection signal of a γ-ray, and an X-ray detecting section for outputting a detecting signal of an X-ray. The X-ray source moves around a bed for placing an examinee. The γ-ray detecting section has a plurality of radiation detectors aligned in the longitudinal direction of the bed and placed around the bed. The X-ray detecting section is positioned in a region formed between one end and the other end of the γ-ray detecting section in the longitudinal direction of the bed. The X-ray source is also positioned in the region. Since the X-ray detecting section is placed in the region, it is possible to accurately combine a PET image and an X-ray computed tomographic 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.

摘要： An image pickup apparatus of a radiological imaging apparatus includes a plurality of radiation detectors arranged in a ring form around a through hole section formed on a casing into which an examinee is inserted. An X-ray source unit having an X-ray source moves in a circumferential direction of the through hole section along a ring-shaped guide rail provided on the casing. Each radiation detector outputs both an X-ray detection signal which is a detection signal of X-rays that have passed through the examinee and a γ-ray detection signal which is a detection signal of γ-rays radiated from the examinee caused by radiopharmaceutical. A computer creates an X-ray computed tomographic image data based on the X-ray detection signal and a PET image data based on the γ-ray detection signal and creates fused tomographic image data using the X-ray computed tomographic image data and the PET image data.

摘要： An imaging apparatus of a radiological imaging apparatus is provided with a first and a second radiation detectors disposed around a hole portion into which a bed is inserted. The first radiation detector includes a detecting portion formed of GaAs of a square having a side of 5 mm and having a thickness of 2 mm. The second radiation detector includes a detecting portion formed of CdTe of a cube having a side of 5 mm. The first radiation detector detects X-rays emitted from an X-ray source and transmitted through an examinee and does not detect γ-rays emitted from the examinee. The second radiation detector detects above X-rays and γ-rays. An X-ray signal processing apparatus processes an X-ray image signal from the first radiation detector and outputs intensity information thereof. A signal discriminating apparatus processes a γ-ray image signal from the second radiation detector and outputs a pulse signal. Thus, the radiological imaging apparatus capable of carrying out radiation examination of the subject by using X-rays and γ-rays can be simplified.

摘要： An X-ray CT apparatus includes: an X-ray generating unit configured to generate an X ray; an X-ray detecting unit including a plurality of X-ray detectors, each configured to detect the X ray generated from the X-ray generating unit and transmitted through an object; and an image generating unit configured to correct and reconstruct signals acquired by the X-ray detecting unit. While crosstalk correction of a plurality of the X-ray detectors is performed at the image generating unit, correction of a locally attenuating component is previously performed and correction of a whole component of the crosstalk is performed when the image is reconstructed.
