[Problem] To provide a communication apparatus that makes a subject's voice more audible. [Means for Solution] A communication apparatus 60 has: a microphone 61 for receiving, during rotation of a rotating section 26, sound containing a voice of a subject 5 to be examined and noise caused by the rotation of the rotating section 26; a DSP 623 for executing filter processing for reducing said noise contained in the sound received by the microphone 61, wherein the DSP 623 determines a frequency of the noise caused by the rotation of the rotating section 26 based on a rotational speed vi of the rotating section 26, and sets a filter characteristic F(ti) for the DSP so that a frequency component of the noise contained in the sound is removed; and a speaker 63 for outputting the sound which contains the voice of the subject 5 and from which the frequency component of said noise has been removed.
