摘要： A practical semiconductor radiation detector capable of collecting electrons rapidly with a large volume is disclosed. A multiple layers of grid electrodes around an anode formed on a semiconductor element limits the generation of the induced charge signal for the anode to the space in the neighborhood of the anode, while at the same time making it possible to collect the electrons rapidly. As a result of limiting the space for generating the induced charge by the grid electrodes, the energy resolution is improved even for a thick semiconductor element. Also, the capability of rapidly collecting the electrons due to the high field strength generated by the grid electrodes makes a sensitive volume of the whole semiconductor and thus achieves a high radiation detection efficiency.

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.

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： The image pickup apparatus of the radiological imaging apparatus of the present invention includes many detector units, a ring-shaped detector support member and an X-ray source circumferential transport apparatus. Each of the detector units is attached to the detector support section in a detachable manner. A plurality of radiation detectors provided for the detector units are arranged in three layers in the radius direction of the detector support member and in three columns in the axial direction of the detector support member. Since the radiation detectors are arranged in three layers in the radius direction, it is possible to recognize the detection position of radiation in the radius direction in detail. Furthermore, since the detector units are attached in a detachable manner, it is easy to replace damaged radiation detectors.

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.

In an accelerator system designed to treat the patient with irradiation of a high-energy ion beam accelerated by a post-accelerator 4 comprising a synchrotron in irradiation rooms 6 to 8, a value of ion beam current to be supplied to the post-accelerator 4 is controlled by a pre-accelerator comprising an ion source 10, quadrupole electromagnet 15, radio frequency quadrupole accelerator 17 and a drift tube type accelerator 19. The accelerator system featuring low power consumption, a long maintenance interval and high reliability can be made available.
