Radiant ray generation control apparatus, radiation imaging system, and method for controlling the same

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...

AI Technical Summary

Benefits of technology

The radiation imaging control apparatus has an exposure switch for controlling the emission of radiation, an acquisition unit for acquiring the driving state of the radiant ray detector, and a control unit for outputting a specific signal via a wired connection. The technical effect is to enable quick and accurate control of the radiation emission and detection process through an easy-to-use and efficient apparatus.

Problems solved by technology

However, signal exchange between the X-ray generator and the X-ray detector as discussed in Japanese Patent Application Laid-Open No. 2000-308632 becomes difficult if the X-ray generator is not provided with a dedicated interface.

When the X-ray detector performs state transition upon detection of X-ray as discussed in Japanese Patent Application Laid-Open No. 11-155847, delayed detection of the activation and deactivation of X-ray emission will cause degradation in image quality.
