Abstract

A radiation imaging control apparatus includes an exposure switch configured to instruct radiation emission, an acquisition unit configured to acquire a first signal indicating that the exposure switch is pressed, a first connection unit configured to detachably connect with a control unit of a radiant ray detector to transmit a second signal indicating the driving state of the radiant ray detector, a second connection unit configured to detachably connect with a control unit of a radiant ray generation apparatus to transmit a specific signal, and a control unit configured to perform control to output the specific signal via the second connection unit upon acquisition of the first and second signals, wherein the second connection unit is a connector for making wired connection.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a radiant ray generation control apparatus, a radiation imaging system, and a method for controlling the same.[0003]2. Description of the Related Art[0004]A digital X-ray imaging system including an X-ray generator for irradiating an object with X-ray, and an X-ray detector for acquiring as digital data an X-ray image representing the intensity distribution of X-ray which penetrated the object has been commercially manufactured.[0005]Such a digital X-ray imaging system performs X-ray imaging while controlling the state of the X-ray detector, such as activation of the X-ray detector and transition to a storage state. Japanese Patent Application Laid-Open No. 2000-308632 discusses a technique for controlling the state of an X-ray detector by transmitting information about an X-ray exposure switch from an X-ray generator to the X-ray detector, thus performing imaging control. Further, Japan...
