Abstract

PROBLEM TO BE SOLVED: To house ultrasonic wave jelly in an easily usable place and to provide a function for warming the ultrasonic wave jelly. SOLUTION: This ultrasonic tomograph device 4 is provided with a probe 2 for transmitting ultrasonic waves to a testee body and receiving reflection echo signals from the testee body. In this case, the ultrasonic wave jelly 3 for tightly adhering the probe 2 to the testee body and preventing the attenuation of the ultrasonic waves is warmed by blowing the heat of a substrate rack by a fan 10.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic tomographic apparatus having a means for heating an ultrasonic jelly.

[0002]

2. Description of the Related Art A conventional ultrasonic tomography apparatus irradiates an ultrasonic beam into a subject from a probe that is in contact with the body surface of the subject, receives a reflected wave from the probe, and receives a reflected wave to obtain a tomographic image of the subject. To create
The tomographic image is displayed on a display device.

[0003] The ultrasonic tomography apparatus thus configured is
In order to obtain better tomographic images, ultrasonic jelly is interposed between the probe and the body of the subject during diagnosis, and the air from the probe, which is an obstacle to the propagation of ultrasound from the probe into the subject, is removed. Preventing intrusion. However, because this ultrasonic jelly has a low temperature,
When performing a diagnosis, the subject is uncomfortable. Therefore, conventionally, in order to raise the temperature of the ultrasonic jelly to an appropriate temperature for the subject, an ultrasonic jelly electric heater is prepared separately from the ultrasonic tomographic apparatus, and measures are taken.

[0004]

However, with the above-mentioned conventional means, it may be difficult to secure an installation place for the ultrasonic jelly warmer and to supply power. Also, depending on the installation location of the warmer, even if an attempt is made to apply the ultrasonic jelly, the operator may not be able to reach the ultrasonic jelly, and the diagnostic efficiency may be reduced.

An object of the present invention is to provide an ultrasonic tomographic apparatus which can store an ultrasonic jelly in an easy-to-use place and has a function of heating the ultrasonic jelly at low cost.

[0006]

In order to achieve the above object, an ultrasonic tomographic apparatus according to the present invention provides a probe for transmitting an ultrasonic wave to a subject and receiving a reflected echo signal from the subject. An ultrasonic tomographic apparatus comprising: a probe and an ultrasonic transmission / reception unit that supplies an ultrasonic signal to the probe and amplifies a signal received by the probe and performs wave phasing. The present invention is characterized in that there is provided a means for warming an ultrasonic jelly which is in close contact with a sample and which prevents attenuation of ultrasonic waves.

[0007] With the ultrasonic tomographic apparatus configured as described above, it is not necessary to newly provide an ultrasonic jelly heater, the space can be maintained, and the discomfort of the subject can be reduced without affecting the diagnostic efficiency. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a diagram in which probe jelly is applied to the probe. A large amount of probe jelly is applied to the probe head so that air does not enter between the probe and the subject.

FIG. 2 is a diagram in which a part of a subject is diagnosed using a probe. Since the probe needs to be applied to the skin of the subject, if the ultrasonic jelly is cold, the diagnostician may call attention to the subject in advance.

FIG. 3 is a diagram showing the structure of the ultrasonic tomographic apparatus. The ultrasonic tomographic apparatus has an operation panel for performing input and output operations by performing a dialog with a substrate rack that obtains a tomographic image by processing emission and reception of ultrasonic waves and a received reflection signal.
Further, it comprises a TV display unit for displaying this tomographic image and a probe which is scanned and irradiated with the ultrasonic beam from the transducer.
Also, there is an ultrasonic jelly required when the probe is brought into contact with the subject. Since ultrasonic jelly is frequently used during diagnosis, a storage case is provided at the lower part of the operation panel to make it easier to take. In order to warm this storage case, the board rack is arranged under the storage case.

FIG. 4 is a sectional view of the ultrasonic tomographic apparatus. Warm air flows out of the substrate rack, and this air passes through the lower part of the ultrasonic jelly storage case and is discharged to the outside from a fan on the rear surface of the apparatus. The storage case is heated by the air radiated from the board rack, and the ultrasonic jelly is heated.

According to the above-described ultrasonic tomography apparatus, the ultrasonic jelly that only comes into contact with the subject at the time of diagnosis is warmed and kept warm without requiring a new electric heater, thereby reducing discomfort of the subject. Will be able to
