Abstract: [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.

Abstract: To provide a technique with which an operator, when talking into a microphone, can recognize whether or not his/her voice is being output from a speaker in a scan room, a CT apparatus 1 has: an operator microphone 41 installed in an operation room R2 for receiving a voice of an operator 81; a patient microphone 2 installed in a scan room R1 for receiving a voice of a patient 80; a speaker 50 installed in the operation room R2 for outputting the voice of the patient 80 received by the patient microphone 2; a speaker 5 installed in the scan room R1 for outputting the voice of the operator 81 received by the operator microphone 41; and a light-emitting section 31 for informing, in the case that the patient microphone 2 has received the voice of the operator 81 output from the speaker 5, the operator 81 that his/her voice is being output from the speaker 5.
