Abstract

PURPOSE:To achieve a switch operation simply and accurately in a short time by displaying whether a switch is valid or invalid for inputting in an recognizable manner when the switch of an operation screen is operated to allow the discrimination of validity or invalidity for inputting of the switch. CONSTITUTION:An operator selects a switch 3 displayed bright alone as such valid for inputting to operate the switch viewing an operation screen 1. For example, when the apparatus acts in real time, the switch 3 is all valid for inputting. A switch is selected from all switches 3a and 3b for image conditions setting items and when the apparatus freezes, the switches 3a-3b are invalid for inputting. So, a switch is selected from the switches 3b and 3d among those for the image conditions setting items and a switch operation is performed to set or alter image conditions.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides a plurality of switches as touch keys for selecting and changing setting conditions of a device when displaying an image on a liquid crystal panel, for example. The present invention relates to an ultrasonic diagnostic apparatus equipped with an operation screen that displays individual characters.

(Prior Art) Conventionally, as an operation screen provided in an ultrasonic diagnostic apparatus, there is a screen as shown in FIG. 7, for example. In the figure, this operation screen 100 is provided on an operation table (not shown) of the ultrasonic diagnostic apparatus, and a switch 101 for selecting or changing the setting conditions of the apparatus when photographing and displaying images of a subject is a touch key. A plurality of images are displayed on the screen 102 of the liquid crystal panel. There are many menu items in which these switches 101 are grouped together, and these items can be divided into multiple pages and displayed on the screen 102.

FIG. 5 shows an example of a menu for setting image conditions, and switches 101a, 101b, 101c, 101d
is a switch for image condition setting items. That is, the switch 101a is a switch for setting the number of color data, the switch 101b is a switch for selecting color display or monochrome display of an image, the switch 101C is a switch for setting an image display width, and the switch 101d is a switch for setting an image contrast. It's a switch. In addition, the switch 101e
, 101f and 101g are menu classification changeover switches, and switches 101h and 101i are page control switches.

Here, the switch 10 displayed on the screen 102
1 in 1. Depending on the setting state of the device, there are some switches whose input is disabled, and whether the input of such a switch is enabled or disabled changes according to changes in the setting state of the device. For example, in the case of the menu shown in FIG. 7, when the device is operating in real time, switch 1 on screen 102
01 are all valid inputs, but when the apparatus is in a frozen state, the switch 101a for the color data number setting item and the switch 101c for the image display width setting item are invalid.

(Problem to be Solved by the Invention) However, in the case of the above-mentioned prior art, when the operator operates the operation screen 100, the operator can distinguish between valid input switches and invalid input switches simply by looking at the switch 101. The operator cannot press switch 1.
It is necessary to operate the switch after determining whether the input of 01 is valid or invalid. Furthermore, if the operator accidentally presses a switch that disables input, the operator may wonder whether the switch is not functioning due to a malfunction of the device or some other cause. As described above, the conventional technology has the disadvantage that operating the operation screen takes time and effort, and erroneous operations often occur.

The present invention has been made to solve the problems of the prior art described above, and its purpose is to enable switch input to be identified as valid or invalid, and to operate the switch easily, quickly, and reliably. An object of the present invention is to provide an ultrasonic diagnostic apparatus equipped with an operation screen that can perform the following operations.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention includes a switch for selecting or changing setting conditions when photographing and displaying images of a subject. An ultrasonic diagnostic apparatus having a plurality of operation screens displayed on the screen is characterized in that when a switch on the operation screen is operated, whether the switch is valid for input or invalid for input is displayed in a distinguishable manner.

(Function) On the operation screen of the ultrasonic diagnostic apparatus of the present invention having the above configuration, when the operator operates a switch, it is possible to identify whether the switch displayed on the screen is input valid or invalid as described above. Since the information is displayed, the operator can immediately determine whether the switch input is valid or invalid just by looking at the operation screen, and can reliably select and operate only the switch whose input is valid. Therefore, the switch can be operated easily and quickly, and erroneous operations can be prevented.

(Example) Below, an example of the present invention will be described based on the drawings. 1st
1 is a plan view showing an operation screen of an ultrasonic diagnostic apparatus according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the configuration of an ultrasonic diagnostic apparatus provided with the same operation screen.

This operation screen 1 is provided on an operation console 10 of an ultrasonic diagnostic apparatus, and similarly to the conventional example shown in FIG.
On the screen 2 of the liquid crystal panel, a plurality of switches 3 are displayed as touch keys for selecting or changing setting conditions for photographing and displaying images of a subject.

These switches 3 are switches for the image condition setting menu similar to the conventional example described above, and the switch 3a is the switch for setting the number of color data, the switch 3b is the switch for selecting color display or black and white display, and the switch 3C is the switch for setting the number of color data. The switch for the display width setting item, switch 3d, is the switch for the contrast setting item. In addition, switches 3e, 3
f and 3g are menu classification changeover switches, and switch 3h.

31 is a page control switch.

In this operation screen 1, when the operator operates a switch, the CPUI 1 performs the switch display operation described later, so that the switch with invalid input and its item display area is displayed darker or has diagonal lines compared to the switch with valid input. will be displayed. For example, when the device is in a frozen state, the switch 3a for the color data number setting item and the switch 3C for the image display width setting item are disabled, and as shown in FIG.
3c is displayed darkly or with diagonal lines.

When photographing and displaying images of a subject (not shown), the ultrasound probe 12 is driven by a transmitting/receiving circuit 14 under the control of a transmitting/receiving control circuit 13, and transmits and receives ultrasound to and from the subject. I do. The reflected echo received by the ultrasonic probe 12 is subjected to processing such as amplification in the transmitter/receiver circuit 14 and output as an electrical signal which is an image information signal.This signal is detected by the detector circuit 15 and converted into a DSC (digital Display means 1 such as a CRT display via a scan converter) 16
7, and the photographed image of the subject is displayed on the display means 17. Also, according to a control signal sent from the CPUI 1, the transmission/reception control circuit 13. The DSC control circuit 18 is connected to the transmitter/receiver circuit 14. Controls the operation of the DSC 16.

Next, the third section describes the operation of the CPUI 1 when the operator operates the operation screen 1 to set and change image conditions.
This will be explained using figures.

First, the CPU II reads the setting state of the device (s t
epl), determines the menu to be displayed on the operation screen 1 according to the operator's instructions from the operation console 10 (ste
p2). Next, with respect to one switch in the menu to be displayed, it is determined by searching whether the input of this switch is valid or invalid using the switch valid/invalid determination table 19 as shown in FIG. 4 (step 3). In FIG. 4, 1 indicates that the switch input is valid, and 0 indicates that the switch input is invalid. If the switch input is valid (step 4)
, this switch is displayed brightly on the operation screen 1 (step 5). If the input to a switch is disabled (step 4), this switch is displayed darkly or with diagonal lines on the operation screen (step 4).
p6). Next, check whether there is a switch to be determined (step 7), and if there is a switch to be determined, 5 t
Return to ep3 and repeat the same operation as above. In this way, the switches are judged and displayed one after another, and when there are no more switches to be judged, the switch judgment and display operation is ended.

While looking at the operation screen 1, the operator selects only the brightly displayed switch 3 as a valid input switch and performs a switch operation. For example, when the device is operating in real time, all switches 3 are valid for input, and a switch is selected from all switches 3a to 3d in the image condition setting items, and when the device is in a frozen state, switch 3 is enabled.
Since the input of a13C is invalid, the user selects one of the switches 3b and 3d among the switches in the image condition setting items and operates the switch to set and change the image condition.

When the operator selects a desired switch 3 and performs an input by operating the switch, this input signal is sent from the console 10 to the CPU II via the input processing circuit 11. In response to this input signal, CPU 1 controls transmission/reception control circuit 1B, DSC
A control signal is sent to the control circuit 18, and the graphic memory 2
0. A display signal is sent to the display means 17 via the adder 22, and an image is displayed on the display means 14 according to the conditions set by the operator.

In the device of this embodiment, when operating the operation screen 1, the switches with invalid input are displayed darkly or with diagonal lines as described above, so that it is possible to distinguish between the switches with valid input and the switches with invalid input. The operator can immediately determine which switches are valid for input just by looking at the operation screen 1, and can quickly select only the switches for which input is valid and switch easily and reliably. operations can be performed. Therefore, the burden on the operator can be reduced and the diagnostic speed can be increased.

FIG. 5 is a plan view showing an operation screen of an ultrasonic diagnostic apparatus according to another embodiment of the present invention, and FIG. 6 is a plan view showing an operation screen of an ultrasonic diagnostic apparatus according to still another embodiment of the present invention. . In FIGS. 5 and 6, the same parts as in FIG. 1 are denoted by the same reference numerals, and explanations thereof will be omitted.

The operation screen 30 shown in FIG. 5 and the operation screen 40 shown in FIG. 6 have the same menu item switches 3 as in the embodiment shown in FIG. When a switch is operated, switches with invalid input disappear and are not displayed, and only switches with valid input are displayed. For example, when the device is in a frozen state, as shown in FIG.
C and its item display parts 4a and 4c disappear and are not displayed,
Only the switches 3b, 3d to 31 whose input is valid are displayed. On the operation screen 40, the item display portion of the switch whose input is invalid is displayed in reverse video. For example, when the apparatus is in a frozen state, as shown in FIG. 6, the item display portions 4a and 4c of the switches 3a and 3c whose inputs are invalid are displayed in reverse video. The other components and operations in these embodiments are the same as those in the above embodiment shown in FIG. 1, so their explanations will be omitted.

In these embodiments as well, the operation screen 30.40
When operating the switch 3, it is clearly displayed whether the input is valid or invalid as described above, so the operator can immediately determine which switch is valid for input just by looking at the operation screen 30.40. , switch operations can be performed easily, quickly, and reliably. In particular, on the operation screen 30, switches with invalid inputs are not displayed, and only switches with valid inputs are displayed, so the menu display is easy to see, and only the switches with valid inputs can be selected and operated without fail.

Note that the present invention is not limited to the above embodiments,
Various modifications are possible. For example, in the embodiment described above, switch 3 may be activated by displaying a switch whose input is disabled darkly or with diagonal lines, by inverting the item display area, or by not displaying the item display area and the switch. Although input is valid or input invalid is displayed in a distinguishable manner, the present invention is not limited to this, and a mark or marker may be written on a switch whose input is invalid, or a blinking display may be performed. Alternatively, only the switches for which input is valid may be marked and displayed with marks, markers, etc.
