The present invention relates to an ultrasonic diagnostic apparatus, and more particularly, to an ultrasonic diagnostic apparatus for automatically performing impedance matching between a main body and a probe of an ultrasonic diagnostic apparatus based on a set ultrasonic diagnostic environment.

Since the ultrasonic diagnostic apparatus has non-invasive and non-destructive characteristics, it is widely used in the medical technology field for obtaining information inside an object such as a human body. Ultrasonic diagnostic apparatus is very important in the medical field because it can provide a high-resolution image of the internal tissue of the human body to the doctor in real time without the need of surgical surgery to directly incision.

The ultrasound diagnosis apparatus electrically stimulates the conversion element to generate an ultrasound signal and transmit the ultrasound signal to an object such as a human body. The ultrasonic signal transmitted to the object is reflected at the boundary of the discontinuous object tissue, and the reflected ultrasonic signal transmitted from the boundary of the object tissue to the conversion element is converted into an electrical signal. Ultrasonic image data of the object is generated by signal processing the converted electrical signal.

On the other hand, since the impedance is different between the main body of the device and one end of the probe in the ultrasonic diagnostic apparatus, an impedance matching means is applied between the probe and the ultrasonic diagnostic apparatus main body to improve the sensitivity and bandwidth of the probe by reducing signal reflection due to the impedance difference. do.

However, in the conventional ultrasonic diagnostic apparatus, an impedance matching means having one constant impedance value is used regardless of the ultrasonic diagnostic environment of the ultrasonic diagnostic apparatus. Accordingly, in the conventional ultrasonic diagnostic apparatus, since the impedance matching between the main body of the apparatus and the probe cannot be performed according to the ultrasonic diagnostic environment, the sensitivity of the probe decreases and the quality of the resulting ultrasonic image is degraded. There was this.

Accordingly, an aspect of the present invention is to provide an ultrasonic diagnostic apparatus capable of automatically performing optimal impedance matching between a main body and a probe of an ultrasonic diagnostic apparatus according to various ultrasonic diagnostic environments.

In an embodiment of the present invention, the probe may include an impedance matching unit installed between a conversion element array and a main body of the ultrasonic diagnostic apparatus to perform impedance matching; And a matching controller for controlling the impedance matching of the impedance matching unit based on the impedance matching information provided from the control unit.

In the present invention, the impedance matching unit preferably includes a plurality of impedance matching elements having different impedances.

In the present invention, it is preferable that the matching controller activates one of the plurality of impedance matching elements based on the impedance matching information.

In the present invention, the impedance matching element is preferably an inductor.

In the present invention, when the impedance matching is completed by the impedance matching unit, the matching controller transmits a matching completion signal to the control unit, and the control unit displays matching completion on the display unit based on the matching completion signal. .

In the present invention, the ultrasound diagnostic environment preferably includes at least one of an image mode selected by a user, a medical application, and a frequency band used.

The ultrasonic diagnostic apparatus according to the present invention can automatically obtain an improved ultrasound image by performing an optimal impedance matching between the main body and the probe of the ultrasonic diagnostic apparatus according to various ultrasonic diagnostic environments set in the ultrasonic diagnostic apparatus. In addition, there is an effect that can improve the user's ease of use of the ultrasound diagnostic device.

Hereinafter, the present invention will be described in more detail with reference to Examples. These embodiments are only for illustrating the present invention, and the scope of rights of the present invention is not limited by these embodiments.

1 is a view showing the configuration of an ultrasonic diagnostic apparatus according to an embodiment of the present invention, Figure 2 is a flow chart for explaining the operation of the ultrasonic diagnostic apparatus according to the present embodiment, with reference to this the present invention As follows.

As shown in FIG. 1, the ultrasound diagnosis apparatus according to the present embodiment is an ultrasound diagnosis apparatus for generating an ultrasound image by transmitting an ultrasound signal to an object and receiving a reflected ultrasound signal reflected from the object. A controller 100 generating and providing impedance matching information based on the result; And a probe 200 that automatically performs impedance matching between the main body of the ultrasound diagnosis apparatus and the probe 200 based on the impedance matching information provided from the controller 100. In addition, the probe 200 may include an impedance matching unit 210 installed between a transducer array 230 and a main body of the ultrasonic diagnostic apparatus to perform impedance matching; And a matching controller 220 that controls the impedance matching of the impedance matching unit 210 based on the impedance matching information provided from the controller 100.

The operation of this embodiment configured as described above will be described in detail with reference to FIGS. 1 and 2.

First, the ultrasound diagnosis apparatus receives various diagnostic environments, various parameters, and the like of the ultrasound diagnosis apparatus from the user through the input unit 400 before performing the ultrasound diagnosis operation (S101).

Subsequently, the ultrasound diagnosis apparatus determines whether various ultrasound diagnosis environments necessary for ultrasound diagnosis are set on the system (S102). The ultrasound diagnosis environment may include at least one of an image mode selected by a user, a medical application, and a frequency band used. In this case, the medical care application means various medical subjects or its medical field, for example, obstetrics and gynecology.

As a result of the determination in step S102, if there is no information set for the ultrasound diagnosis environment, the process proceeds to step S107, in which the ultrasound diagnosis apparatus is set according to a default value (default condition) basically set on the ultrasound diagnosis apparatus. Impedance matching is performed between the body and the probe. That is, in this case, the matching controller 220 controls the impedance matching unit 210 to perform impedance matching according to the basic impedance matching information set as the default value.

On the other hand, if there is information set for the ultrasonic diagnostic environment as a result of the determination in step S102, the control unit 100 determines the optimal impedance matching condition previously stored or preset according to various ultrasonic diagnostic environments of the ultrasonic diagnostic apparatus. It calculates (S103). That is, the controller 100 calculates an optimal impedance matching condition corresponding to information of an ultrasound diagnosis environment, for example, an image mode selected by a user, a medical application, a frequency band used, and the like. At this time, the information on the optimum impedance matching conditions corresponding to the various ultrasonic diagnostic environments to be set is pre-built in the memory unit 300 of FIG. 1, and the control unit 100 is pre-stored in the memory unit 300. Based on the available information, the optimum impedance matching condition is calculated.

Next, the control unit 100 transmits impedance matching information or a control signal according to the optimum impedance matching condition calculated above to the matching controller 220 of the probe 200. (S104).

Then, the matching controller 220 causes the impedance matching unit 210 to automatically adjust the proper impedance matching between the main body of the ultrasound diagnosis apparatus and the probe 200 in response to the impedance matching information transmitted from the controller 100 or a control signal according thereto. To perform (S105). Here, the impedance matching unit 210 includes a plurality of impedance matching devices (not shown) having different impedances, and the matching controller 210 may be configured in the ultrasonic diagnostic environment among the plurality of impedance matching devices based on the impedance matching information. By activating any suitable one, an optimum impedance match can be made between the probe 200 and the device body. The impedance matching unit 210 is installed between the conversion element array 230 and the main body of the ultrasonic diagnostic apparatus to perform impedance matching.

The impedance matching element included in the impedance matching unit 210 may be configured as an inductor, and each impedance matching element is preferably arranged in a shape suitable to minimize the interference effect caused by the induced magnetic field.

Next, when the impedance matching is completed, the matching controller 220 transmits a matching completion signal indicating that the impedance matching is completed to the control unit 100 of the main body (S106).

Then, the controller 100 displays that the impedance matching is completed on the display unit 500 based on the matching completion signal, so that the user can know that the impedance matching suitable for the set ultrasonic diagnostic environment has been made. Of course, even when impedance matching is performed after step S107, the controller 100 may display that the impedance matching is completed on the display unit 500.

As described above, the ultrasonic diagnostic apparatus according to the present embodiment enables the optimum impedance matching between the main body and the probe of the ultrasonic diagnostic apparatus according to various ultrasonic diagnostic environments set in the ultrasonic diagnostic apparatus, thereby improving ultrasonic quality. Not only can the image be obtained, but also the user's ease of use of the ultrasound diagnostic apparatus can be improved.
