Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention 1 (Industrial Application Field) The present invention relates to an ultrasonic diagnostic apparatus in which an ultrasonic probe is provided with a probe switch for improving operability.

(Prior art) While an ultrasound probe that transmits and receives ultrasound waves to and from a subject is in contact with the surface of a desired area of the subject, any operating switch on a control panel on which various operating switches are arranged is pressed. A selection operation is performed. In this case, in order to improve the operability of the ultrasound panel, the operation switch (probe switch) is most often selected during diagnosis.
It is common practice to provide an ultrasonic probe with an ultrasonic probe. For example, a real/freeze changeover switch is selected as this operation switch. According to this, when switching between full and freeze during diagnosis, the operator does not have to reach for the control panel each time; All you have to do is perform the operations.

By the way, the operation switches that are frequently selected during diagnosis are not limited to the real/freeze changeover switch, but there are several others. Therefore, in order to further improve operability, it is desirable to replace several frequently selected operation switches with an ultrasound probe. However, due to the limitations of the hardware configuration of an ultrasound diagnostic device, From the viewpoint of operability, it is impossible to install multiple operation switches like that on an ultrasonic wave generator.
In reality, the number of operation switches is limited to one or two.

(Problems to be Solved by the Invention) In this way, in the conventional ultrasonic diagnostic apparatus, the operability during diagnosis is limited, perhaps because of the switch provided on the ultrasonic switch. The problem is that it doesn't move very far.

The present invention has been made to address more than 11 problems,
An object of the present invention is to provide an ultrasonic diagnostic apparatus in which any operation switch on a control panel can be selected even if the ultrasonic probe has only one probe switch.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention has the following features:
A CPU that controls the /R unit and the DSC unit;
The apparatus is characterized by comprising a probe switch interface section which outputs the desired switch data to the CPU each time the probe switch provided on the ultrasonic probe is set in advance by the CPU and switches the probe switch provided on the ultrasonic probe.

(Function) Every time the switch (operation) is turned on the switch provided on the ultrasonic probe, a switch signal is output from the probe switch interface section to the CPU.

This switch date is set in advance by the CPU, and can be changed arbitrarily by the CI U as necessary. The probe switch can have the same function as the one operating switch by providing Brisera 1 to (1).

Therefore, operability can be improved during diagnosis.

(Embodiment) Fig. 1 is a water type block diagram of an ultrahigh wave diagnostic apparatus according to an embodiment of the present invention.
A probe switch 11 is provided on the probe 10. The probe switch 11 is a normal bushy-on type switch f that turns on only when it is pressed. T, /R (transmission 7
/receiving) unit 12 sends and receives electrical signals to and from the ultrasound probe 10, and the reception signal (TI) obtained from the subject is converted into an electrical signal by the ultrasound probe 10 and then transmitted to the ultrasound probe 10. 1-/' R units 1 to 12 input the signal, which is processed and sent to the DSC (Digital Speed Converter) unit 13.
3 converts the input signal from A/D and writes it to the digital frame memory, and when read, converts this signal from D/A to a standard TV (television) signal, Display the image on 1V14.

The control panel section 16 includes various operation switches necessary for diagnosis, such as a display mode changeover switch.

A real/freeze changeover switch, etc. is arranged, and when any operation switch is operated, the corresponding data is transferred to the CP.
Manpower U1b. The CPU 15 is based on the human power data from the -1 control panel section 1G, and the
2 and DSCSC unit 13.

The probe switch interface section 17 (") is configured as shown in FIG. - Every time you switch (operate) the bus switch 111, this Δn, Af signal is input,
Output the desired switch code data to the CPU. The switch data is configured to be arbitrarily changeable by the CPU 15. The switch switch 1 corresponds to the function of the operation switches on the switch 1 to the roll panel section 1G, and its function changes each time CD3 and CD11 are operated. The function of the probe switch 11 can be specified using a menu screen as shown in FIG. 2, for example. In the case of Fig. 2, the switch function indicated by * is selected.
Each time you operate 1, the PJ function 'B', 'B/M
”, “PW”, and “CW” are arranged in the order of Zino 1~.

Next, the probe switch interface section 17 in FIG.
The configuration will be explained with reference to FIG.

Regarding an example in which the probe switch 11 functions as a display mode changeover switch as shown in the menu screen of Fig. 2,
If you change C explanation, if 3 II, “B/M”.

4 switches corresponding to 4 types of display modes: ``PW'', ``CW'' - data ``'70+1''.

"71H", "'72H", "73)-de'(
+-+ indicates hexadecimal numbers) are set in advance by the CPU 15 and stored in registers 31, 32, 33, and 34 respectively (
Under the control of the CPU 15, data is manually input to each register 31 to 34 via the data bus BD, and an address is manually input to the address decoder 35 via the address bus BA.
Addresses are manually entered from 5 to each register 31 to 34. The on/off signal of the bus switch 11 is sent to the jitter removal circuit, and the other is sent to the gate 40. The output of the counter 38 is inputted to a decoder 39.
The output is sent to each register 31 to 34 via path A to
is input. Each time the probe switch 11 is operated, the switch code data stored in each register 31 to 34 is sequentially enabled, passes through the gate 40, and is sequentially output to the CPU 15.

The CPU 1b polls each operation switch of the control panel section 16 and the probe switch interface section 17 to check whether each operation switch is turned on or off at a constant cycle. In this case, the polling cycle is usually equal to 301 to 308 indicate No. 18 in each route.

Next, the operation of this embodiment will be explained.

FIG. 4 shows signals 301 to 308 in each path in FIG.
shows the time chart. 301 is the output signal of the blow 1 switch 11, 302 is the chattering removal circuit 3
7 output signal z, 303 is the output signal 304 of the counter 38
307 is the output signal of the digital camera 39, and 308 is the output signal of groups 1 to 40.

Figure 4 (probe switch here) is pressed -〇
- When not, the output horn signal 301 is kept at l-level. In this state, at time t1, probe switch 1
When 1 is pressed J (on), the output signal 301 momentarily shows a chattering signal, and after ΔT between 0 and 3C, it stabilizes and changes to the - level. However, the output signal 302 is tl
Immediately after the chattering removal circuit 37
・Since the counting signal SC is removed, it immediately changes to L level 1. At this tl, the output 303 (count number) of the counter 38 maintains the value (0) before t1. O, and output signals 304 to 307
If the level before 1 is maintained as 1, only the output signal 304 becomes L level. The output of this result register 31 is enabled. Next, when the probe switch 1 is set to H level (A-) at 12, the chattering iris 6 is removed from 302 in the same way as when it is on, so that it immediately changes to the H level at t2. At the same time, the output of counter t38 is incremented by 1 to 3034 and one count is increased.

As a result, the output signal 304 changes from 1- to the alarm level, and at the same time, the output signal 305 changes from H to [- level. However, the output signals 306 and 307 remain at the level before t2. As a result, the output of register 32 instead of register 31 is enabled.

With the above operation, register 31 is enabled, η
In other words, when the J-lobe switch 1 is turned on,
During this period, the pre-stored switch data "701-D" is output from the register 31, and during this time, the gate 40 receives the output No. 18 or 1111 of 1 level, so "70 H" is The signal passes through games I to 40 as it is and is sent to the CPU 15 as an output signal 308. Therefore, the CPU 15 performs the necessary control operations to display the "F3" 7-code image of the ultrasonic wave on the TV screen. That will happen.

Next, when the switch 11 is turned on again at t3, only the output signal 302 changes to the 1-level, and then when it is turned off at t4, the output signal 3 of the counter 38 is turned off.
03 is further incremented and counted up by 7IJ+1. This causes the output signal 305 to change from 1- to H.
At the same time as the level changes, the output signal 306 changes from 1-1 to E.
- change in level η 1, but output signal 307.304
remains at the level before t4. As a result, the output of register 33 is enabled instead of register 32.

During the period t3-t4 in the above operation 1-, the switch needle data “71” stored in advance is sent from the register 32.
H" is output and added to the CPU 15 as an output signal 308. Therefore, the ultrasonic wave "B/M" is on both sides of l-V.
The mode image will be displayed.

Thereafter, each time the probe switch 11 is turned on, a similar operation is performed and the contents of the registers 31 to 34 are sequentially output to the CPU 15. As an example, the menu screen of the probe switch 11 is used. I have shown an example of specifying the * mark ■0 in the figure, and this kind of menu screen is preset A.

A plurality of probe switches B, C, etc. can be prepared, and the function of the probe switch 11 can be specified separately for each probe switch. For example, in preset A, 'B'', ''B/M
",""PW","CW" display mode changeover switch, preset B can be specified as "Real/Norise" changeover switch, and by switching 1 reset A and B, initial settings for each function can be made. I can do it.

In this embodiment, we have described the case where the on/off detection of the operation switch is performed by polling, but when it is on, CF) U
Multiply 15 including υ1, then switch to CPU 15.
-1~Read data JBy the interrupt method, C can be performed bC-. Furthermore, the configuration of the probe switch-interface section 17 can be modified in various ways. In addition, in the embodiment, although the example uses four registers, only one register is used, and the switch-initial data to be set in the register is reset by the CPU each time the switch is turned on. Therefore, it is also possible to perform the operation of sequentially switching the switch code data using software.

Furthermore, it is also possible to input only probe switch ON/OFF signals to the CPU and override the functions of a series of probe 1 switch interface sections within the software.

The contents of the menu screen items can be combined in any way depending on the control panel section.

[Effects of the Invention] As described above, according to the present invention, even if there is only one boolean switch, it can have the same function as the ten operation switches on the control panel, thereby improving operability. 1゜
