  • RADIATION IMAGE ACQUISITION DEVICE, AND IMAGE PROCESSING METHOD
    Publication number: 20130270448
    Abstract: 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.
