US 2018/0024268 A1 · IONIZING RADIATION IMAGE DATA CORRECTION

Abstract

In one example, an image data correction device is configured to an ionizing radiation detection device, wherein the ionizing radiation detection device is configured to detect ionizing radiation in a plurality of energy ranges transmitted through an object to which radiation is irradiated from a radiation source, the radiation detection device comprising: a first detector for detecting ionizing radiation in a first energy range that is transmitted through the object to generate first radiation image data; a second detector configured in parallel to the first detector with a predetermined region sandwiched between the first and the second detectors, for detecting ionizing radiation in a second energy range that is transmitted through the object to generate second radiation image data. The first and the second detectors are configured to receive the ionizing radiation concurrently so that the first and the second image data are generated concurrently. The image data correction device comprises; at least one processor, and at least one memory storing program instructions that, when executed by the at least one processor, cause the device to: digitally determine a correction value for the second radiation image data based on a width of the predetermined region. In other examples a method and a computer program product has been discussed along with the features of the image data correction device.
