Abstract

A radiation image capturing method, a radiation image capturing system, and a radiation information system are provided. In the present invention, a console checks a cassette ID (specified cassette ID) sent from an RIS server as the cassette ID of a radiation detecting cassette that is planned to be used to capture a radiation image, and a cassette ID (actual cassette ID) that is read by the console from a radiation detecting cassette which is placed in an operating room or an image capturing room and which is to be actually used to capture a radiation image, with each other. Based on the result of the cassette ID check, the console determines whether to permit a radiation image to be captured or not.
