Abstract
An X-ray image photographing apparatus includes an image obtaining portion for obtaining an X-ray distribution transmitted through an object, a grid detecting system having a construction for obtaining information from a grid side by the action of inserting the grid for decreasing scattered rays into the apparatus, and detecting at least one of the presence or absence of the grid, the kind of the grid and the presence or absence of the replacement of the grid by the use of the construction, an image processing system for image processing and outputting image data collected by the image obtaining portion, and a memory portion preserving therein a plurality of sets of image processing parameters for controlling the image processing system. The image processing system selects the image processing parameters preserved in the memory on the basis of at least the result of the detection by the grid detecting system and executes image processing.
