Abstract: A radiation detecting cassette houses therein a detector for detecting a load applied to the radiation detecting cassette when a patient has moved. It is determined whether or not the patient has moved in an image capturing process based on the load detected by the detector. If it is judged that the patient has moved, then a warning is displayed, and a radiation image of the subject is inhibited from being captured.

Abstract: The present invention relates to a radiation image processing apparatus and a processing method. A processing condition selector selects from a processing condition memory a processing condition for extraction or removal of a specific object in radiation image information. The processing condition includes two different image capturing conditions which are provided to a radiation source controller. The radiation source controller controls a radiation source with each image capturing condition to apply radiation to a subject and a solid-state radiation detector stores radiation image information of the subject. An image processor performs a weighted subtraction using stored radiation image information in accordance with the processing condition to achieve extraction or removal of the specific object. The resultant radiation image information is displayed on a display unit.

Abstract: The present invention relates to a radiation image capturing system. A radiation detector of a radiation detecting cassette detects a radiation that has passed through a patient, and an accumulated exposed radiation dose calculator calculates an accumulated exposed radiation dose by accumulating radiation image information detected by the radiation detector, at every image capturing.

Abstract: A radiation image capturing system detects the position of a radiation detecting cassette disposed below a patient and the position of a radiation source for emitting a radiation, based on the differences between the propagation times of radio waves emitted from an antenna device to an image capturing apparatus and the radiation detecting cassette. Based on the detected positions, the relative positions of the image capturing apparatus and the radiation detecting cassette are calculated, and then compared with each other by a position determining unit to judge how the image capturing apparatus is positioned with respect to the radiation detecting cassette. If the image capturing apparatus is not positioned in head-on facing relation to the radiation detecting cassette, then a warning is issued, and an actuating mechanism moves the image capturing apparatus to an appropriate position.
