Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for displaying operating conditions in an ultrasonic diagnostic apparatus together with tomographic images on a monitor screen.

2. Description of the Related Art Conventionally, in ultrasonic diagnostic apparatuses, various operating conditions for obtaining ultrasonic tomographic images as well as ultrasonic tomographic images are simultaneously displayed on a monitor screen as parameters such as numerical values and symbolic data.

In general, it is possible to change the operating conditions while the device is in use within a certain range, and when making changes, use the control panel's keyboard, etc. to input the condition item to be changed and the change condition value. This input content is detected by the switch detection section to change the operating conditions, and also changes and displays numerical values and symbolic data (hereinafter referred to as parameters) related to the operating conditions on the monitor screen.

Problems to be Solved by the Invention However, in the conventional method of displaying operating conditions in ultrasonic diagnostic equipment, when a condition item to be changed or its change condition value is entered from a keyboard, etc., the parameter display on the monitor screen is not immediately displayed. Therefore, it is difficult for the operator to check which parameters have been changed after inputting them.

For this reason, for example, if an operating condition item to be changed or its change condition value is entered incorrectly, the input error must be identified based solely on the degree of change in the tomographic image, which is extremely difficult in practice. There has been a problem in that the test may proceed without noticing input errors, resulting in disadvantages when making a diagnosis.

The present invention is intended to solve the above-mentioned problems, and its first purpose is to highlight the display of changed parameters within a predetermined time, so that the operating condition parameters to be changed can be displayed immediately after input. It is an object of the present invention to provide a method for displaying operating conditions of an ultrasonic diagnostic apparatus, which makes it easy to check for input errors.

A second object of the present invention is to enable the parameter display to be highlighted again after the highlighted display has returned to the normal display after a predetermined period of time has elapsed, thereby ensuring reliable inspection. An object of the present invention is to provide a method for displaying operating conditions of an ultrasonic diagnostic apparatus that can improve performance.

Means for Solving the Problems In order to achieve the first object, the present invention operates a timer that operates for a predetermined period of time when a new operating condition parameter is input as the operating condition is changed. While this timer is operating, the input new operating condition parameters are highlighted and displayed simultaneously with the ultrasonic tomographic image, and when the timer stops operating, the new operating condition parameters are highlighted and displayed normally. It was returned to display and displayed at the same time as the ultrasound tomographic image.

Furthermore, in order to achieve the second object, the present invention reactivates the timer after the timer has stopped operating, so that the new operating condition parameters that have returned to normal display due to the timer stopping are highlighted again. This allows the images to be displayed simultaneously with ultrasound tomographic images.

Effect The first invention uses the method described above to highlight the changed parameters within a predetermined period of time.
Immediately after inputting the operating condition parameters to be changed, it is possible to easily check for input errors.

Moreover, the second invention improves the reliability of operation by making it possible to highlight the parameter display again after the highlighted display has returned to the normal display after a predetermined period of time has passed, using the above method. be able to.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
FIG. 1 is a block diagram showing a schematic configuration of an ultrasonic diagnostic apparatus for realizing a method of displaying operating conditions of an ultrasonic diagnostic apparatus according to an embodiment of the present invention.

In Fig. 1, numeral 1 is a control panel consisting of a keyboard and various switches, etc., and is used to give instructions to change operating condition parameters and to re-highlight operating condition parameters that have returned to normal display from highlighted display. This is for inputting data.

2 is a switch detection unit that determines and processes the content of data input from the control panel 1; specifically,
Whether the input data instructs to change the operating condition parameter and highlight the changed operating condition parameter, or to switch the operating condition parameter that has returned from highlighting to normal display to highlighting again. Processing is performed to determine whether it is an instruction.

When determining that the content of the data input from the control panel 1 instructs to change the operating condition parameters and highlight the changed operating condition parameters, the control switch detection unit 2 detects the first It outputs a character data generation signal to the second character generator 3, and also outputs parameter data regarding items for changing operating conditions and their change values to the second character generator 4.

Further, the switch detection section 2 includes a control panel 1
If it is determined that the content of the data input from
outputs a character data generation signal to the second character generator 3, and outputs a character data generation signal to the second character generator 4.
Outputs the re-output signal to.

The first character generator 3 includes a switch detection section,
When the character data generation signal is input from 2,
Character data for highlighting parameters related to input data is generated and output to a switch 6, which will be described later.

On the other hand, when parameter data regarding an item whose operating condition is to be changed and its change value is inputted from the switch detection unit 2, the second character generator 4 detects the operating condition value already set for the corresponding item. Thereafter, the parameter data regarding the operating conditions of each item including this is constantly outputted as normal display data to the inverting unit 7, which will be described later.

Furthermore, when the second character generator 4 receives the re-output signal from the switch detection section 2,
The currently output normal display data is continuously output to the inverter 7, which will be described later.

Reference numeral 5 denotes a timer that starts operating when data is manually input to the switch detection section 2, and when it starts operating, it outputs an on signal to close the switch 6, which will be described later.
After a predetermined time has elapsed, an off signal is output to open the switch 6.

This switch 6 is connected on one side to the first character generator 3 and on the other side to the reversing section 7, and while the switch 6 is closed by the operation of the timer 5, the signal from the first character generator 3 is connected. The character data is input to the inverter 7.

When the switch 6 is closed, the reversing section 7
The character data from the second character generator 3 and the normal display data from the second character generator 4 are synthesized and output as highlighted display data to the video signal synthesis section 8, and when the switch 6 is open, Only the normal display data from the second character generator 4 is output as is to the video signal synthesis section 8.

The video signal synthesis section 8 synthesizes the highlighted display data or normal display data inputted from the inversion section 7 and the tomographic image signal data inputted from a probe (not shown) via the scan conversion section 9, and generates a video signal. It is output to the monitor 10 as .

Next, the display operation of the operating conditions of the ultrasonic diagnostic apparatus having the above configuration will be explained.

When an examination using an ultrasound diagnostic apparatus is started, an ultrasound tomographic image 21 sent from the probe and a group of operating condition parameters 22' according to the normal display 23, which are set in advance before the start of the examination, are displayed as shown in FIG. As shown in (A), the images are simultaneously displayed on the monitor 1o.

Now, select Dynamic R from Control Panel 1.
When data instructing to change the operating conditions for rDRJ (hereinafter referred to as rDRJ) and highlight the operating condition parameters for rDRJ after the change is input, the switch detection unit 2 detects this and starts the timer 5. When activated, the timer 5 outputs an on signal to the switch 6 to close it.

In parallel with this, when the switch detection unit 2 outputs a character data generation signal to the first character generator 3, the first character generator 3 generates a Character data based on a box-shaped mark 24 as shown in FIG. 2(B) is generated and outputted to the inverter 7 via the closed switch 6.

On the other hand, when the switch detection unit 2 outputs parameter data of new operating conditions regarding rDRJ to the second character generator 4, the second character generator 4
generates parameter data regarding the operating conditions of each item including new parameter data regarding the operating conditions of "DR", ie, normal display data, and outputs this to the inverting section 7.

Then, the reversing unit 7 synthesizes only the parameter data related to rDRJ out of the normal display data regarding the operating conditions of each item with the character data represented by the box-shaped mark 24 to create inverted display data, and uses this as highlighted display data for video signal synthesis. output to section 8.

The video signal synthesis unit 8 changes the operating condition parameters in the rDRJ column in the operating condition parameter group 22 on the monitor 10 to normal as shown in FIG. The display 23 is switched to the highlighted display 25 and displayed on the monitor 10.

Thereafter, when the timer 5 starts counting and a predetermined period of time has elapsed, the timer 5 outputs an off signal to the switch 6.
Along with this, the switch 6 is opened, and the character data from the first character generator 3 is no longer input to the inverting section 7.

Therefore, the new operating condition data regarding rDRJ outputted from the inverting unit 7 to the video signal synthesizing unit 8 changes from highlighted display data to normal display data, and the display of operating condition parameters regarding rDRJ on the monitor 10 changes to highlighted display 25.
The normal display 23 is returned to.

By the way, after the display of the operating condition parameters related to "DR" returns from the highlighted display 25 to the normal display 23, if you want to confirm again what the changed operating condition parameters were, that is, whether the changed operating conditions were rDRJ. inputs data from the control panel l that instructs to switch the operating condition parameters related to the latest item whose operating conditions have been changed to the highlighted display 25 again.

Then, the switch detection unit 2 changes the content of the data input from the control panel 1 from the highlighted display 25 to the normal display 2.
It is detected that the operating condition parameter restored to 3 is an instruction to switch to the highlighted display 25 again, and the first
A character data generation signal is output to the character generator 3, and the timer 5 is restarted.

The timer 5 outputs an on signal to the switch 6 to close it, while the first character generator 3, which receives the character data transmission signal from the switch detection section 2, generates parameters related to the operating conditions of the rDRJ. Character data based on a box-shaped mark 24 for switching from the normal display 23 to the highlighted display 25 again is generated, and this is output to the inverter 7 via the switch 6 which is closed by the ON signal from the timer 5.

In this case, the second character generator 4 continues to output the currently output normal display data to the reversing unit 7, and the reversing unit 7 outputs the parameters related to rDRJ among the normal display data regarding the operating conditions of each item. Only the data is combined with the character data formed by the box-shaped mark 24 to produce inverted display data, which is output to the video signal synthesis section 8 as highlighted display data.

As a result, the operating condition parameters related to rDRj on the monitor 10 are switched from the normal display 23 to the highlighted display 25 again.

Thereafter, when the timer 5 starts counting and a predetermined period of time has elapsed, the timer 5 outputs an off signal to the switch 6 to open it. As a result, the reversing section 7
The operating condition data of rDRJ output to the video signal synthesis unit 8 changes from highlighted display data to normal display data, and the operating condition parameter monitor 1 regarding "DR" changes from highlighted display data to normal display data.
The display above 0 returns from the highlighted display 25 to the normal display 23 again.

It should be noted that the timer 5 in this embodiment is configured such that the set time from when it starts operating until it outputs the off signal can be adjusted and changed as necessary.

In addition, the monitor 10 shown in FIG. 2(A) and FIG. 2(C)
Needless to say, although not shown, a gray scale indicating the gradation level of the brightness of the screen is also displayed at the same time.

Furthermore, in this embodiment, a box-shaped mark 24 is used as character data, and the changed operating condition parameters are highlighted 25 by inverted display with this as the background. This character data is shaded, underlined, By using frames and parentheses, etc., the highlighted display 31, 32, 33 and 34 as shown in Fig. 3(A) to Fig. 3(D) is
You may also do this.

In addition, character data can be used as instruction symbols such as arrows,
As shown in FIG. 3(E), a highlighting display 35 may be used in which an instruction symbol such as an arrow is displayed next to the corresponding parameter.

Alternatively, the monitor 10 may be a color monitor, and the corresponding parameter may be highlighted in a different color from other parameters (not shown).

As described above, according to the operating condition display method of the ultrasonic diagnostic apparatus of the present embodiment, by displaying the changed parameter in a highlighted display 25 within a predetermined time, the operating condition parameter to be changed can be input immediately after input. This makes it easier to check for mistakes.

In addition, after the predetermined time has passed and the parameter display returns from the highlighted display 25 to the normal display 23, the parameter display is changed to the highlighted display 25 again.
The reliability of the operation can be improved because it can be switched to

Effects of the Invention As described above, according to the first invention, when a new operating condition parameter is input as the operating condition is changed, a timer that operates for a predetermined period of time is activated. During this time, the new operating condition parameters that have been input are highlighted and displayed simultaneously with the ultrasound tomographic image, and when the timer operation stops, the highlighting of the new operating condition parameters is returned to the normal display and the ultrasound Since it is displayed at the same time as the tomographic image, by highlighting the changed parameters within a predetermined time, it is easier to check for input errors immediately after inputting the operating condition parameters to be changed. .

Further, according to the second invention, by reactivating the timer after the timer has stopped operating, the new operating condition parameters that have returned to normal display due to the timer stopping are highlighted again and displayed simultaneously with the ultrasonic tomographic image. Since the parameter display is now displayed, it is possible to highlight the parameter display again after the highlighted display has returned to the normal display after a predetermined period of time has elapsed, thereby improving the reliability of operation. .
