X-ray image pickup device

Abstract

Abstract PURPOSE:To prevent a required image from being lost by opening fully the aperture stop or inhibiting image-pickup when a radioscopic time is a prescribed time or below. CONSTITUTION:A radioscopy selection start signal 21 is generated from a radioscopy selecting switch, and a high level signal 23 is inputted to an AND gate 25 by a timer means 22 until a prescribed time T. Further, a fully opening command signal 26 of aperture stop is outputted from the AND gate 25 until the time reaches the prescribed time T. Since the aperture stop is opened fully when the radioscopic time is short in this way, the loss of a required image due to over-stopping of the aperture is avoided. Moreover, the similar effect is attained even by outputting a command signal inhibiting the X-ray pickup until reaching the prescribed time T in place of the fully opening command signal.
