<p>PURPOSE:To obtain a radioscopic image high in quality in a state where the object is fixed. CONSTITUTION:It is characterized in that the device includes a collimator means 23 which is provided in front of a detecting means 21, and is moved in a to- and-fro motion integrally with the detecting means 21 by ascanning means, and concurrently has an aperture 24 roughly identical in angle to an incident angle of radiation to the detecting means 21 at the maximum movement position, a connecting means which connects a radiation generating means 11 to a radiation detecting means 20 so as to hold them, and a signal processing means which collects the output signal of the detecting means 21, processes the output signal to make the picture, and thereby obtains a radioscopic image.</p> |
