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.
