摘要： The radiation detection module (20) is provided with a semiconductor element (1) having a plurality of pixels (Pn), radiation detection elements (30) in which a plurality of first electrodes (31n) are arranged along one side of the semiconductor element (1), and a second electrode (32m) is disposed astride a plurality of pixels (Pn) along the other side, and which output detection signals when a radioactive ray comes incident on the detection pixels (Pn), and a support PCB (21) placed to stand along the direction in which the radioactive ray comes incident. The support PCB (21) has a connection section (21a) detachably connectable to an external connecting section. Radiation detection elements (30) are connected on the support PCB (21) to fabricate a signal read-out circuit having mutually-perpendicular wiring in a pseudo way and that the incident position of the radioactive ray is identified by coincidence determination of the detection signals.

摘要： An image processing device of a radiation image acquisition device (100) uses a weighted filter to perform a smoothing (processing S102) on an image obtained by counting the number of incident gamma rays. The image processing device suppresses pixel values of a threshold value or less on the smoothed image (processing S103). Further, the image processing device again applies a weighted and smoothing filter to the image processed by a threshold-value processing, to expand the pixels of the accumulation portion (processing S104); thus providing an image that facilitates finding the accumulation portion of a radioisotope.

摘要： There are provided a radiation detection module, a printed circuit board, and a radiological imaging apparatus which make it possible to enhance spatial resolution without increasing channel number, and thereby to perform high-accuracy diagnosis. The radiation detection module includes a plurality of radiation detectors, and a wiring board on which the plurality of radiation detectors are mounted in a manner of being arranged in at least a radiation traveling direction. Here, on the wiring board, a pair of the radiation detectors which are adjacent to each other in the radiation traveling direction are electrically connected to each other, thereby configuring one detector structure (i.e., detection channel). Moreover, the radiation detectors are mounted onto the wiring board such that respective connection parts of electrodes, which are to be electrically connected to each other, are in a mutually-facing state.

摘要： A PET apparatus comprises a plurality of detector units in the circumferential direction, wherein the detector unit includes a plurality of unit substrates therein, and wherein the unit substrate includes: a plurality of detectors upon which a γ-ray is incident; and an analog ASIC and digital ASIC for processing a γ-ray detection signal outputted by each of the detectors. The analog ASIC includes two slow systems having mutually different time constants, each of which outputs a pulseheight value. A noise determination part of the digital ASIC determines whether a relevant detection signal is an intended γ-ray detection signal or a noise based on a correlation between the pulseheight values, and a noise counting part counts the number of times of noise determination, and a detector output signal processing control part controls the signal processing with respect to an output signal from a relevant detector based on the count.
