<P>PROBLEM TO BE SOLVED: To provide a tomographic apparatus capable of preventing misidentification or the like during depolarization. <P>SOLUTION: This tomographic apparatus for regenerating a tomographic image of a subject, based on measurement data acquired by detecting the radiation emitted from the subject includes: a radiation-presence signal output part for outputting a radiation presence signal showing existence of a radiation, corresponding to the detection degree of the radiation in a radiation detector; a depolarization execution command part for outputting an execution command for executing depolarization of the radiation detector; a holding output part for outputting as a holding signal, a signal level of the radiation-presence signal, immediately before start of the depolarization, when an execution command is output from the depolarization execution command part; a logic sum output part for outputting a logic sum of a detection signal output from the radiation presence signal output part and the holding signal output from the holding output part; and an informing part for informing of output from the logic sum output part as an informing signal for informing that the radiation is under measurement. <P>COPYRIGHT: (C)2010,JPO&INPIT |
