摘要： A radiological imaging apparatus of the present invention comprises an image pickup device and a medical examinee holding device that is provided with a bed. The image pickup device includes a large number of radiation detectors and radiation detector support plates. A large number of radiation detectors are mounted around the circumference of a through-hole and arranged in the axial direction of the through-hole. The radiation detectors are arranged in three layers formed radially with respect to the center of the through-hole and mounted on the lateral surfaces of the radiation detector support plates. Since the radiation detectors are not only arranged in the axial direction and circumferential direction of the through-hole but also arrayed in the radial direction, it is possible to obtain accurate information about a γ-ray arrival position in the radial direction of the through-hole (the positional information about a radiation detector from which a γ-ray image pickup signal is output). The use of accurate information about γ-ray arrival increases the tomogram accuracy. As a result, the present invention enhances the tomogram accuracy, that is, the PET examination accuracy.

摘要： Each semiconductor radiation detector used for a nuclear medicine diagnostic apparatus (PET apparatus) is constructed with an anode electrode A facing a cathode electrode C sandwiching a CdTe semiconductor member S which generates charge through interaction with γ-rays. Then, a thickness t of the semiconductor member S sandwiched between these mutually facing anode electrode A and cathode electrode C is set to 0.2 to 2 mm. Furthermore, the devices are mounted (laid out) on substrates in such a way that the distance (distance of conductor) between the semiconductor radiation detector and an analog ASIC which processes the signal detected by this detector is shortened. Furthermore, the substrates on which the detectors are mounted are housed in a housing as a unit (detector unit).

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： 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 image forming apparatus of the present invention is generally made up of a sheet storing unit and an image forming unit removably mounted on the top of the sheet storing unit when in use. The sheet storing unit accommodates a sheet tray loaded with sheets and selectively movable into the sheet storing unit to an operative position or out of the same to an inoperative position. A locking mechanism inhibits the sheet tray from being moved to the inoperative position. An unlocking device unlocks the locking mechanism when the image forming unit is mounted to the sheet storing unit. When the image forming unit is removed from the sheet storing unit, the sheet storing unit is prevented from falling down due to a moment ascribable to the pull-out of the sheet tray.
