JPH05269125A - X-ray ct device capable of voice speed adjustment - Google Patents

Abstract

PURPOSE:To constitute the X-ray CT voice generating device for generating an instruction voice to an examinee, so that an operator can adjust a speed of the instruction voice in accordance with the examinee. CONSTITUTION:The X-ray CT voice generating device is constituted so that a clock synchronized with a voice data store memory 2 and a voice synthesizing circuit 3 is selected by a clock switching circuit 5, a signal read out of the voice synthesizing circuit is amplified by an amplifier of 4, and an instruction voice is outputted from a loudspeaker of 6. In such a way, in the case of a conventional voice generating device, speed adjustment of an instruction voice to an examinee cannot be executed, but since it can be executed, an operator executes the speed adjustment in accordance with the examinee and the X-ray CT device can be utilized effectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray C whose voice speed can be adjusted to automatically emit an instruction voice given to a subject at the time of measurement.
Regarding the T device.

[0002]

2. Description of the Related Art An X-ray CT apparatus gives instructions such as "please breathe and stop", "please ease" when measuring the subject. Conventionally, this type of device presets a typical word and automatically generates it, but its voice speed is the same as the speed set at the time of registration.

[0003]

In the conventional device, the instruction voice is generated at the set speed. For this reason, for example, the voice speed is slowed to make it easier to recognize for an old person or the like who has poor voice recognition. On the contrary, there is a problem that the operator himself cannot adjust the voice speed such that the voice speed is increased and the measurement time is shortened.

An object of the present invention is to make it possible to adjust the voice speed of a preset instruction voice according to the purpose of use of the operator, to improve the easiness of voice recognition of the subject and to shorten the measurement time. A voice adjustable C that reduces the burden on the examinee
It is to provide a T device.

[0005]

According to the present invention, there is provided a memory, which is incorporated in a console, in which data of a voice to be inspected for a subject is stored, and a voice synthesizing circuit for processing the data read from the memory. And an amplifier for amplifying the signal of the voice synthesizing circuit and a speaker for receiving the signal from the amplifier to generate a voice. A switching circuit for switching the frequency of the clock for synthesis was provided.

[0006]

According to the present invention, by switching the clock by the switching circuit, the audio data is read from the memory in synchronization with this clock, passed through the audio synthesis circuit, amplified by the amplifier, and output to the speaker.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a block diagram showing the configuration of a voice generator for an X-ray CT apparatus according to the present invention. The apparatus shown in FIG. 1 comprises a console 1, a voice data storage memory 2, a voice synthesizing circuit 3, an amplifier 4, a clock switching circuit 6 and a speaker 6. The console 1 shown in FIG. 1 has a clock switching circuit 5 which is not found in a general X-ray CT apparatus.
Is included.

In this configuration, the operator switches the voice speed adjustment button, and the clock switching circuit 5 selects the clock to be input to the voice data storage memory 2 and the voice synthesizing circuit 3. In the voice data storage memory 2, this clock is a read clock, and in the voice synthesizing circuit 3, this clock is a synthesizing clock. Now, five clocks having different frequencies are prepared for the clock switching circuit 5, and CK ₋₂ to CK ₊₂ are set from the lower frequency to the higher frequency. Figure 2
The voice speed switching button 7 shown in (1) is set to x0.6 to x1.4 from the slower to the faster switching setting, which corresponds to the clock described above.

When the slowest speed mode × 0.6 is selected by the voice speed adjusting button shown in FIG. ₂ , the switch is switched to CK _-2 having the lowest frequency in the clock switching circuit 5 of FIG. In synchronization with this, data is read from the voice data storage memory 2 and passes through the voice synthesis circuit 3 of 3,
It is amplified by the amplifier 4 and the speaker 6 produces a voice. Similarly, press the voice speed adjustment button 7 to × 0.8, × 1
.. is set, the clock is switched to the corresponding clock, and the speaker 6 outputs the instruction voice at each speed.

FIG. 3 shows a clock and how it changes with time. According to the present embodiment, the operator can adjust the speed of the instruction voice according to the subject, and can issue a command such as respiratory arrest according to this speed.

[0011]

According to the present invention, since the operator can easily change the instruction voice speed, the old man or the like can easily recognize the instruction by slowly giving the instruction voice. For other cases, the instruction voice speed can be increased and the measurement time of the subject can be shortened.
The restraint time can be shortened.
