DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention belongs to the technical field of medical diagnostic equipment incorporating an audio device.

[Technical background of the invention and its problems]

Conventionally, in medical diagnostic equipment, in order to use radiation for diagnosis, various devices that collect radiation data from patients and control devices that command the operations of the various devices have been designed to ensure operator safety. ,
placed in separate rooms. In order to eliminate the psychological anxiety of patients who are isolated in a diagnostic room during radiation diagnosis, medical diagnostic equipment is equipped with an audio device that communicates the operating status of the medical diagnostic equipment to the patient.

FIG. 1 shows an example of a medical diagnostic device equipped with an audio device.

In Figure 1, 1 indicates a diagnostic device that collects medical information about a subject, such as an X-ray CT.
2 is a control device that controls the X-ray CT scanner 1, and 3 is an audio controller that outputs a coded signal indicating the status of control by the control device 2. Reference numeral 4 indicates an amplifier that amplifies the audio signal outputted from the storage device 4 by associating the coded signal with the audio signal, and reference numeral 6 indicates a speaker that converts the audio signal from the amplifier 4 into sound. be.

In the X-ray diagnostic apparatus shown in FIG. 1 having the above configuration, when the control device 2 outputs data indicating the operating status of the CT scanner 1 to the audio controller 3, the audio controller 3 outputs data indicating the operating status of the CT scanner 1. The coded signal shown in FIG. and outputs a voice message to the patient, for example, ``Please hold your breath.''

By the way, in the case of the CT scanner 1, after inputting various control information to the CT scanner 1 and completing the setup state of the CT scanner 1, the operator etc. After confirmation, the scan starts, so it is preferable to convey the voice message to the patient, for example, "Please hold your breath," immediately before the scan starts.

However, when trying to transmit an audio message in a timely manner just before the start of a scan, conventional medical diagnostic equipment equipped with an audio device cannot control the scan mode of the CT scanner 1 (e.g., multi-scan, single scan, dynamic scan, etc.) or the scan location ( For example, the time from the setup state to the operational state differs depending on the head, neck, abdomen, etc., and the time from the operational state to the start of scanning differs depending on the operator.
Requires large capacity audio storage. Furthermore, if a variety of voice messages are to be transmitted to patients in response to various actions, a voice storage device with an increasingly large capacity is required.

FIG. 2 shows an embodiment of the present invention.

A medical diagnostic device, such as an X-ray CT device, which is an embodiment of the present invention, is a diagnostic device that irradiates a subject, such as a patient, with X-rays and collects X-ray data.
A control command signal is output to the X-ray CT scanner 11 to control the X-ray CT scanner 11 based on the X-ray exposure conditions input by the operator, and the operation of the X-ray CT scanner 11 is performed. A control device 12 outputs signals indicating the situation etc. to a delay controller 13 and an audio controller 14, which will be described later.
A delay controller 13 outputs delay data specifying a delay time corresponding to the operation status of the CT scanner 11 to the audio controller 14, and a signal output from the control device 12 is inputted to control the X-ray CT scanner 11. After a delay time specified by the delay data output from the delay controller 13, the address signal designating the address in the voice storage device 15 that stores the voice signal for the voice message corresponding to the operating situation etc. is sent to the voice storage device 16. At the same time, an unvoiced sound signal of a constant frequency is sent to the amplifier 1 via the audio storage device 15 so as to emit an unvoiced sound during the delay time.
an audio controller 14 that outputs to an amplifier 16; and a memory that stores audio signals corresponding to voice messages at predetermined addresses and outputs audio signals corresponding to address signals output from the audio controller 14 to an amplifier 16; Audio storage device 15 and audio storage device 15
The audio signal output from the audio storage device 15
It has an amplifier 16 that amplifies the unvoiced sound signal outputted from the audio controller 14 via the audio controller 14, and a speaker 17 that makes the unvoiced sound signal and the audio signal audible.

In the above case, the delay controller 13, the audio controller 1
