Abstract

PURPOSE:To make it possible for an operator to designate accurately and easily a photographing part by providing a control device for displaying 'designated' which, when certain part of a switch region is touched, makes a display state of a corresponding part of a human body model figure to a specified 'designated' state. CONSTITUTION:A human body model figure 20 displayed on LCD 11 with a touch panel is divided into 7 parts which are set in such a way that switch regions 21 to 27 of the touch panel 13 overlap on each part. An operation reading part 16 of a control device 14 monitors an output signal of the touch panel 13 and when it detects that an icon 31 is touched, it informs a display output part 15 of that and icons 35 and 36 are alternatively switched and displayed. E.g. if the icon 36 is touched, it is displayed with a mesh to display a reception of an operation and the human body model figure 20 is alternatively displayed. Then, if an operator touches e.g. the waist part, the operation reading part 16 detects it at the switch region 26 to inform the display output part 15 of it and a calling parts 17 and the display output part 15 displays the waist part of the human body model figure 20 with a mesh display.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an imaging region specifying device for an image diagnostic apparatus.
More specifically, the present invention relates to an imaging region specifying device that can reliably and easily specify the region of the human body to be imaged.

[Prior Art] An X-ray CT device is a typical image diagnostic device.
It is necessary to set a large number of parameters (commonly referred to as techniques) such as ray tube voltage, X-ray tube current, and X-ray layer thickness.

For this reason, a conventional X-ray CT apparatus is provided with an operation panel 50 as schematically shown in FIG. 7, for example.

The type of parameter is written on the panel (51 in the figure).
), the parameter values are displayed on a 7-segment LED display 52. An up key 61 and a down key 62 are provided respectively corresponding to the parameter display.
By pushing these, each parameter value can be changed and set to a desired value.

Generally, different parameter values are set depending on the part of the human body to be imaged, but it is troublesome to set the parameter values individually each time the part changes, so it is necessary to set a combination of parameter values for each part of the human body in advance. You can call them all at once with a single touch. 63 is a part designation switch for this batch call. These position designation switches 63 have built-in lamps (73 in FIG. 8).

Above the region selection switch 63, there is a translucent panel 64 in the shape of a human body.The panel 64 is divided into regions, and a lamp (74 in Fig. 8) is installed inside. .

As shown in FIG. 8, the part specifying switch 63 and lamps 73 and 74 are connected via a control section 70.

The control unit 7o turns on the lamp 7 while waiting for an operation to specify a part.
3 is blinking, and when the operator presses one of the part designation switches 63, only one of the corresponding lamps 73 lights up. At the same time, one of the corresponding lamps 74 is lit so that the operator can confirm which part has been designated.

[Problems to be Solved by the Invention] In the conventional device shown in FIG.
and each part of the human body-shaped translucent panel 64 are shifted in position. This is because the size ratio of each part of the human body is different, but the size ratio of the switch is constant.

However, if the position of the part designation switch and the part of the human body figure are misaligned, the operator is confused and often takes time to designate the part.

Therefore, it is conceivable to use a switch in the shape of the human figure itself, but this is not practical as it would be a special component.

Furthermore, depending on the specifications, it may be necessary to change the type or number of parts, but there is also the problem that such changes cannot be handled flexibly.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an imaging region specifying device for an image diagnostic apparatus, which allows an operator to specify a region accurately and easily, and also allows flexible adaptation to changes in the type and number of regions. It is about providing.

[Means for Solving the Problems] An imaging region specifying device for an image diagnostic apparatus of the present invention includes a human body model figure display means for displaying a human body model figure on a screen, and each part of the human body model figure displayed on the screen. a touch panel having respective areas overlapping with each other as switch areas; a designated line display control means for displaying the human body model figure in a predetermined designation waiting state when waiting for an operation to designate an imaging region; a specified display control means for changing the display form of the part of the human body model figure corresponding to the switch area to a predetermined specified form when any of the switch areas is touched while a figure is being displayed; The present invention is characterized in that it is provided with a designation waiting display control means for outputting a designation signal for a designated part.

In the above configuration, for example, a blink display or a reverse display can be used as the designation waiting mode.

In addition, in the above configuration, as the specified form, for example, a mesh display or a filled display can be used. [Function] The human body model figure display means displays the body model figure on the screen, and the specified line display control means displays the body model figure on the screen. For example, make it blink.

If the operator touches the desired part of the human body model shape,
Because the touch panel shows the touched area,
You can also find the desired part.

Therefore, the designated display control means displays that part of the human body model figure in a mesh display, for example, and the designated display control means outputs a designation signal for that part.

Since the operator only has to directly touch the desired area, the operator can specify the area accurately and easily.

Furthermore, since the human body model figure is displayed on the screen, it is possible to flexibly deal with changes in the type and number of body parts.

[Example] Hereinafter, the present invention will be explained in more detail with reference to Examples shown in the drawings. Note that this invention is not limited to this.

FIG. 1 shows an imaging region specifying device (third
This figure shows the external appearance of the operating section of the X-ray CT apparatus 1 incorporating 10) in the figure. 2 is a CRT for displaying tomographic images, and 11 is an LCD with a touch panel (LCD 1 as shown in Figure 3).
2 and a touch panel 13).

As shown in FIG. 2, the CD 11 with a touch panel has the following information:
A human body model figure 2o is displayed.

Further, key-shaped icons 31 to 36 are displayed.

The human body model figure 20 is divided into seven parts, and the switch areas 21 to 27 of the touch panel (13 in FIG. 3) are set to overlap with each other for each part.

FIG. 3 is a schematic diagram of the imaging region specifying device 10.

The display output unit 15 of the control means 14 displays the human body model figure 20 and the icons 31 to 36 on the LCDI 2, and at the start of setting the imaging conditions, the icon 31 is displayed as an outline display and a menu as shown in FIG.・Switch alternately to Soshu display.

The reason why the icons 31 are alternately displayed as described above is to confirm that the settings are new, and to prompt the next operation from the apparatus side for a so-called guided scan operation.

The operation reading section 16 of the control means 14 monitors the output signal of the touch panel 13, and when it detects that the icon 31 has been touched, it sends a message to that effect to the display output section 1.
Let 5 know.

Then, as shown in FIG. 5, the display output unit 15 displays the icon 31 in a mesh display to indicate that the operation has been accepted.

Next, the icons 35 and 36 are alternately displayed in the same manner, and for example, when the icon 36 is touched, the icon 36
is displayed as a mesh to indicate that the operation has been accepted.

Next, the human body model figures 20 are displayed alternately.

Then, the operator touches, for example, the waist of the human body model graphic 20.

The operation reading section 16 detects that the waist is touched in the switch area 26, and notifies the display output section 15 and the calling section 17 of the touch.

The display output unit 15 displays the waist of the human body model figure 20 in a mesh display, as shown in FIG. This allows the operator to easily confirm the designated region.

The calling unit 17 reads out the values for the waist region from among the various parameter values corresponding to the imaging conditions of each region stored in the parameter value storage means 19 and supplies them to the control output unit 18 .

The control output section 18 outputs the parameter values to each section of the imaging device.

Thereafter, icons are displayed and the touch panel is read in the same manner in a predetermined order.

Thus, according to this imaging region specifying device 10, the region can be specified accurately and easily, and the burden on the operator is reduced.

Furthermore, since the display on the LCD 12 and the switch area on the touch panel 13 can be easily changed, it is possible to flexibly deal with changes in the type and number of parts.

[Effects of the Invention] According to the imaging region specifying device of the image diagnostic apparatus of the present invention,
Since the operator only has to touch the desired part directly, the part can be specified accurately and easily.

Furthermore, it becomes possible to flexibly deal with changes in the type and number of parts, etc.
