Abstract
An apparatus using a two-dimensional radiation sensor for acquiring X-ray penetration images or the like. A monitoring radiography is performed with a small dose before a production radiography. A radiographic condition for the production radiography, specifically a radiation emitting period or a tube current of a radiation generator, is computed based on a ratio between a quantity of charges in a region of interest collected from the two-dimensional radiation sensor in time of the monitoring radiography and a desired quantity of charges in the region of interest in time of the production radiography. The production radiography is carried out based on a result of the computation to acquire a high quality image.
