Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic scanning ultrasonic diagnostic device that allows simultaneous viewing of ultrasound images of internal organs and sounds produced by the internal organs.

Conventionally, when searching for body tissues using an electronic scanning ultrasound diagnostic device, a pulse voltage is applied to a portion of multiple piezoelectric elements to generate pulsed ultrasonic vibrations, and the generated ultrasonic pulses are emitted into the body. Then, the ultrasound echoes reflected from within the body are received again by the same piezoelectric element, and the tissue in a specific direction and its movement can be determined from the position, speed, and strength of the reflection. A method of observing and knowing a tomographic image inside the body by electronically scanning a piezoelectric element is used. That is, the acoustic impedance and absorption rate differ depending on the tissue materials in the body, and a doctor makes a diagnosis by observing real-time tomographic images obtained from reflected echoes obtained from these using a CRT or the like. However, the resolution of this ultrasound image is limited by the frequency and beam thickness, and the noise component is also high, so the information may not be sufficient for a doctor's diagnosis.
Diagnosis requires considerable skill. Therefore, doctors may have no choice but to rely on their own experience to make a diagnosis.

This invention was developed to solve the above-mentioned problems, and by combining visual and auditory senses, it is possible to observe the movements of organs such as heart valves, etc., in order to improve the diagnostic effect by providing more information. It is an object of the present invention to provide an ultrasonic diagnostic device that can perform an accurate diagnosis by simultaneously listening to sounds emitted by the organ, such as a beating sound.

Next, the present invention will be described with reference to an illustrated embodiment.

FIG. 1 is a block diagram of a device according to the invention. In the figure, 1 is an ultrasonic transducer unit,
Reference numeral 2 denotes a microphone unit, and the ultrasonic transducer unit 1 and the microphone unit 2 are built into the ultrasonic probe 3, and transmit and receive ultrasonic signals and detect acoustic signals, respectively. The microphone unit 2 is attached to the surface of the ultrasonic probe 3, and the mounting surface is constructed so as to be covered with a thin film made of, for example, metal, which is waterproof and sufficiently transmits acoustic vibrations. 4 is an ultrasonic diagnostic device, 5 is a display, 6 is a low frequency amplifier, and 7 is a speaker.

In order to perform diagnosis using the apparatus configured as described above, an ultrasonic transducer unit 1 consisting of a large array of ultrasonic transducer elements that emits or receives ultrasonic waves by applying the probe 3 to the human body is used. Apply an ultrasonic pulse voltage to cause pulsed ultrasonic vibration, emit the generated ultrasonic waves into the body, and send the ultrasonic echoes reflected from the body back to the same ultrasonic transducer unit 1. The ultrasonic diagnostic device 4 receives the real-time tomographic images of internal organ tissues.
In addition to displaying and observing sounds on a display device 5 such as a CRT, the microphone unit 2 detects sounds emitted by internal organs, and the signals are amplified by a low frequency amplifier and input to a speaker 7 to be transmitted from the organs. You can output and listen to the sounds it makes. If the oscillation sound of the ultrasonic transducer is input to the microphone unit 2 and interference sound is generated, insert a low-pass filter in front of the low-frequency amplifier 6 to remove the influence of the interference sound. can do. Generally, the ultrasonic diagnostic apparatus 4, the display 5, the low frequency amplifier 6, and the speaker 7 are incorporated into the main body 8 of the ultrasonic diagnostic apparatus according to the present invention (FIG. 2). Therefore, by applying the ultrasonic probe 3 to the subject, it is possible to easily capture state-accurate images of the organs to be diagnosed as well as the sounds emitted from the organs. More accurate diagnosis can be made.
