X-ray imaging device

Abstract

When a signal Swith a pulse width corresponding to an entire X-ray irradiation period is input, a pulse P(signal S) with a predetermined pulse width is output at an input timing of the signal S, and when a new signal Sis input during output of the pulse P, the pulse P, being output, is extendingly output further for the above pulse width from the input timing of the signal S. Then in a state in which either or both of the signal Sand the pulse Pare being input, a pulse P(signal S), with a pulse width corresponding to a period of the input, is output at a start timing of the input period, and when the pulse Pis input, the imaging unitis controlled to start imaging based on a start timing of the pulse P. An X-ray imaging apparatus that can appropriately detect an imaging start timing and can perform taking of a good X-ray image while preventing malfunctions due to noise is thereby realized.
