IMAGE PROCESSING DEVICE, RADIATION DETECTING DEVICE, AND IMAGE PROCESSING METHOD

摘要

According to an embodiment, a device includes first and second generators, a detector, and a corrector. The first generator is configured to generate a first image based on data corresponding to photons with a first energy from among data that is obtained based on an energy of radiation that has passed through a subject. The second generator is configured to generate a second image based on data corresponding to photons with a second energy. The detector is configured to detect, in the second image, a second block having a similar pattern of pixel values to a first block included in the second image. The corrector is configured to correct pixel values of a third block in the first image corresponding to the first block based on new pixel values of the third block that are calculated by using pixel values included in a fourth block in the first image.

1. An image processing device comprising:
a first generator configured to generate a first image based on first data corresponding to photons with a first energy from among data that is obtained based on an energy of radiation that has passed through a subject bombarded with the radiation; a second generator configured to generate a second image based on second data corresponding to photons with a second energy different from the first energy; a detector configured to detect, in the second image, a second block having a similar pattern of pixel values to a first block included in the second image; and a corrector configured to
calculate, by using pixel values included in a third block in the first image that is positioned corresponding to position of the first block in the second image and pixel values included in a fourth block in the first image that is positioned corresponding to position of the second block in the second image, new pixel values of the third block, andperform a correction on pixel values of the third block based on the new pixel values of the third block.
