Abstract

PURPOSE:To simplify operation to obtain an optimum ultrasonic picture when a mode is frequently switched and diagnosis is executed by keeping a newest parameter setting value and using the kept parameter setting value when the mode is selected. CONSTITUTION:At the time of initial set, a setting part 24 stores the initial value of a parameter and the present value of an operating part 30 to a newest data memory 23. When identifying, information ID are inputted and prescribed operation is executed, a registering part 26 reads a registered parameter setting value 50 from a registering memory 25 and updates the contents of the newest data memory 23. When the mode is selected, the newest data memory 23 is retrieved and the correspondent parameter setting value 50 is read and delivered to respective setting subject parts such as a B-mode gain control part 16. When the mode is switched, the parameter setting value 50 of the mode after the switching is extracted from the newest data memory 23 and set to the respective parts. When the input of registering operation is executed, the registering part 26 stores the parameter setting value 50, which is kept in the newest data memory 23, to the registering memory 25 and registered together with the ID.

[Industrial application field]

The present invention relates to an ultrasonic diagnostic apparatus, and particularly to a parameter setting method for obtaining an optimal ultrasonic image.

The ultrasound diagnostic equipment has a B mode that displays the cross section of the object,
Doppler mode that displays temporal changes in blood flow velocity; B/D simultaneous mode that displays B mode and Doppler mode simultaneously;
It is equipped with various modes such as C0LORB mode, which displays the blood flow velocity distribution in color on the cross section of the subject (B mode).
-Make a comprehensive diagnosis by frequently switching modes for human patients and monitoring each ultrasound image.

In order to optimally adjust these ultrasound images, various parameters are set for each mode, including:
For example, there is a common parameter for each mode, such as the B mode gain, and if it is attempted to set this parameter to an optimal value for each mode, there is a problem in that it must be readjusted every time the mode is switched.

Furthermore, when reexamining the same patient, it is desirable to be able to set the same parameters as before, and for this reason, there is a need for an ultrasound diagnostic apparatus that automatically sets parameters.

[Conventional technology]

FIG. 3 is a diagram showing a display panel and an operation panel of an ultrasonic diagnostic apparatus, and FIG. 4 is a block diagram of a conventional ultrasonic diagnostic apparatus.

In the ultrasonic diagnostic apparatus shown in FIGS. 3 and 4, when a mode is selected using the mode selection key 7 provided on the operation unit 30, the probe 15 transmits an ultrasonic wave corresponding to that mode, and the reflected wave is The ultrasound image of the mode received by the probe 15, such as B mode, M mode, Doppler mode, and B/D mode, is displayed on the monochrome display surface 4 as C0.
The LORB modes are each displayed on the color display surface 3.

B mode is a mode in which the object is scanned and a cross section of the object is displayed using echoes.
ty Time Control (hereinafter the operating means will also be referred to as STC) B-mode gain (also representing the operating means) that adjusts the overall gain of lO1 11, display depth, etc. Among these, STC10 and B-mode gain 11 are potentiometers. etc. are used and set as analog quantities.

The B/D mode is a mode in which the B mode and the Doppler mode are alternately switched to display, for example, the cross section of the subject on the right side of the monochrome display surface 4, and the temporal change in blood flow velocity due to the Doppler signal on the left side, respectively, in real time. The parameters for displaying the cross section of the subject are set using the same operating means as in B mode, and the parameters for displaying blood flow velocity include the sample direction, a direction display for specifying the sample position, and a cursor displayed on the cross section of the subject. and set using the trackball 6.

In the COLORB mode, the blood flow velocity distribution is displayed in color on the cross section of the subject, and the display of the cross section of the subject is set using the same operating means as in the B mode.

The monochrome display surface 4 has a menu display surface 9 for selecting other variations, and the parameter selection key 8 is used to set, for example, the frequency of a filter that removes low frequency components of the received signal.

Among the above operating means for setting parameters, B mode gain 11. STC10 etc. are commonly used for all modes related to B mode, and the setting status is read and set in real time, so for example, switching to 7iCOLORn mode that displays the optimal cross section of the object in n mode, When the n-mode gain is lowered to make it easier to see the blood flow velocity distribution, the cross-section of the object when the n-mode is restored is as follows:
Displayed with the n mode gain set in C0LORn mode.

This also occurs when switching between n mode and B/Dn mode.

Parameter setting operations will be described with reference to FIG. 4 for the n-mode gain 11 and STC 10 as examples of the operating section 30 common to all modes.

The received signal (echo signal) received by the probe 15 when the n mode is iH selected has its total gain (n mode gain) controlled by the n mode gain control section 16, and then is sent to the STC section 1.
In step 7, correction corresponding to the distance is performed.

The amplitude information (luminance modulation information) of this gain-corrected echo signal is separated by the n-mode signal processing unit 18 into reception direction and distance, stored in the frame memory 20, and displayed as a cross section of the object.

In order to observe this displayed cross-section of the object and obtain an optimal display, the n-mode gains 11 and 5TCIO are adjusted, and the setting unit 14 periodically adjusts the n-mode gains 11 and 5TCIO. STC
10, and reset each setting value to the n-mode gain control section 16 and the STC section 11, respectively.

Next, when switching to C0LORn mode, Doppler and n-mode ultrasounds are transmitted alternately, and the n-mode reception signal and Doppler signal corresponding to the transmitted ultrasounds are sent to the n-mode signal processing unit 18, respectively, and the Doppler signal After being identified and processed by the processing unit 19, the frame memory 2
0 and displayed simultaneously.

At this time, the setting section 14 reads the setting states of the n-mode gain 11 and the STC 10 and sets them in the n-mode gain control section 1G and the STC section 17, respectively, as in the B mode.

In this way, in the simultaneous mode, the signal processing in the single mode is performed independently and then combined and displayed simultaneously, so the operating means for parameter setting is
(n mode) and simultaneous mode (n mode), and the parameters are set in the setting state at that time.

[Problem to be solved by the invention]

As described above (, operation unit common to each mode (n mode gain,
If an attempt is made to obtain an optimal ultrasound image by adjusting the STC (STC, etc.) in each mode, readjustment must be made each time the mode is switched, which poses a problem in that it impedes diagnosis.

There is also a desire to make a diagnosis using the same parameters in the case of a re-examination.
