(First Embodiment)
First, an example of the X-ray diagnostic apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram showing an example of an X-ray diagnostic apparatus according to the first embodiment. As shown in FIG. 1, the X-ray diagnostic apparatus according to the first embodiment includes an X-ray tube, an X-ray movable aperture, an X-ray tube holding device, an X-ray detector, a standing radiography table, and a recumbent radiography table. Equipped with a console and so on. Further, the X-ray tube, the X-ray movable aperture, the X-ray tube holding device, the X-ray detector, the standing radiography table, and the recumbent radiography table provided in the X-ray diagnostic apparatus according to the first embodiment are arranged in the examination room. , The console is located in the control room. In the following, the X-ray tube, the X-ray movable aperture, the X-ray tube holding device, the X-ray detector, the standing position photographing table, the lying position photographing table and the like arranged in the examination room are also described as an imaging system. As shown in FIG. 1, the imaging system arranged in the examination room and the console arranged in the operation room are interconnected.

The X-ray tube shown in FIG. 1 exposes X-rays using a high voltage supplied from a high voltage generator (not shown). In addition, the X-ray movable diaphragm controls the X-ray irradiation field for the purpose of reducing the exposure dose to the subject and improving the image quality of the image data. The X-ray tube holding device holds the X-ray tube and the X-ray movable throttle by an arm, and by driving the arm, the position of the X-ray tube and the X-ray movable throttle is moved to a photographing position, a retracted position, or the like. Here, the X-ray tube holding device is a ceiling traveling type, and the positions of the X-ray tube and the X-ray movable throttle can be moved by traveling on the rail laid on the ceiling surface.

In addition, the X-ray detector converts the X-ray information transmitted through the subject into image data and transmits it to the console in the operation room. Here, as shown in FIG. 1, the X-ray detector is installed on a standing radiography table or a recumbent radiography table. The standing radiography table holds the X-ray detector by an arm whose one end is connected to the rail, and the X-ray detector can be slid up and down by moving the arm on the rail. In addition, the recumbent imaging table is provided with a top plate on which the subject is placed, and an X-ray detector is placed on the lower part of the top plate.

Here, the console shown in FIG. 1 is a single console that integrates a system that sets and manages shooting conditions and collects image data, and a system that processes, displays, and manages images. For example, when two consoles for setting and managing shooting conditions and collecting image data and a workstation for image processing, display and management are installed, a space for that amount is required. In the first embodiment, space can be reduced by integrating the system into one console. Note that this is an example, and two units may be installed: a console for setting and managing shooting conditions and collecting image data, and a workstation for image processing, display, and management.

For example, the console acquires the imaging conditions set for each device in the examination room, displays the acquired imaging conditions on the display, and presents them to the operator. In addition, the console accepts the setting of shooting conditions from the operator who has referred to the shooting conditions. In addition, the console notifies each device in the examination room of the imaging conditions set by the operator. This point will be described in detail later.

In addition, the console controls each device in the examination room to perform shooting and collect image data. For example, the X-ray diagnostic apparatus shown in FIG. 1 exposes a subject standing in front of a standing radiography table to X-rays from an X-ray tube and erects the X-rays that have passed through the subject. By detecting with an X-ray detector installed on the imaging table, imaging in a standing position is performed. Further, for example, the X-ray diagnostic apparatus shown in FIG. 1 exposes an X-ray from an X-ray tube to a subject placed on a top plate provided on a recumbent radiography table and transmits the subject. By detecting the X-rays with an X-ray detector installed on a recumbent radiography table, radiography in the recumbent position is performed. In addition, the console executes preset image processing on the collected image data. In addition, the console changes image processing and operates workflow by operating from a mouse, keyboard, or the like. In addition, the console displays images on a display, temporarily stores images, and transfers images.

Next, an example of the configuration of the X-ray diagnostic apparatus 1 according to the first embodiment will be described with reference to FIG. FIG. 2 is a block diagram showing an example of the configuration of the X-ray diagnostic apparatus 1 according to the first embodiment. As shown in FIG. 2, the X-ray diagnostic apparatus 1 according to the first embodiment includes a high voltage generator 101, an X-ray tube 102, an X-ray movable throttle 103, an X-ray detector 104, and an X-ray. It includes a control circuit 105, an aperture control circuit 106, a display 107, an input circuit 108, a storage circuit 109, and a processing circuit 110. The display 107, the input circuit 108, the storage circuit 109, and the processing circuit 110 are included in, for example, the console shown in FIG.

The high voltage generator 101 supplies a high voltage to the X-ray tube 102, and the X-ray tube 102 exposes X-rays using the supplied high voltage. The X-ray movable diaphragm 103 controls the irradiation region of X-rays exposed from the X-ray tube 102. Here, the X-ray tube 102 and the X-ray movable throttle 103 are supported by, for example, the X-ray tube holding device shown in FIG. 1, and the X-ray tube holding device is controlled by the processing circuit 110. And the position of the X-ray movable throttle 103 is moved.

The X-ray detector 104 detects the X-rays that have passed through the subject P. For example, the X-ray detector 104 has detection elements arranged in a matrix. Each detection element converts X-rays transmitted through the subject P into an electric signal, stores the X-ray, and transmits the stored electric signal to the processing circuit 110. Here, the X-ray detector 104 may be installed on either the standing radiography table or the lying position radiography table according to the position of the subject P in the radiography, and the standing radiography table and the recumbent position may be installed. It may be installed on both sides of the shooting table.

The X-ray control circuit 105 controls the exposure of X-rays to the subject P by generating a high voltage in the high voltage generator 101 and supplying the generated high voltage to the X-ray tube 102. Here, the X-ray control circuit 105 controls the applied voltage, application time, application timing, etc. of the high voltage generator 101 according to the photographing conditions notified from the processing circuit 110, and the tube current and tube voltage of the X-ray tube 102. , X-ray irradiation time and other imaging conditions are controlled. The diaphragm control circuit 106 adjusts the opening degree of the diaphragm blades of the X-ray movable diaphragm 103, and controls the irradiation range of X-rays emitted from the X-ray tube 102.

The display 107 displays the shooting conditions. For example, the display 107 displays the shooting conditions set for each item under the control of the processing circuit 110. In the following, among the imaging conditions set for each item, the imaging conditions set for the items expressed by numerical values such as tube current, tube voltage, and X-ray irradiation time are also described as condition values. The shooting conditions displayed on the display 107 will be described in detail later.

In addition, the display 107 displays a GUI (Graphical User Interface) for receiving instructions from the operator. For example, the display 107 displays a display area for displaying a plurality of preset values (hereinafter, also referred to as preset values) set in advance for each item such as tube current, tube voltage, and X-ray irradiation time. The display area and preset values will be described in detail later. In addition, the display 107 displays an image generated by the X-ray diagnostic apparatus 1.

The input circuit 108 receives various instructions from the operator who operates the X-ray diagnostic apparatus 1. For example, the input circuit 108 has a mouse, a keyboard, buttons, a trackball, a joystick, a touch panel, and the like, and converts an input operation received from an operator into an electric signal and outputs the input operation to the processing circuit 110. For example, the input circuit 108 receives an input operation for setting the shooting conditions from an operator who has referred to the shooting conditions displayed on the display 107.

In the following, a case where the display 107 is a touch panel and the input circuit 108 has the display 107 will be described as an example. In such a case, the input circuit 108 receives various instructions from the operator by detecting a tap operation, a long press operation, a pinch operation, a swipe operation, a flick operation, and the like performed on the display 107. In the following, in order to perform an input operation on the input circuit 108, a case where the operator touches the screen of the display 107 with a finger will be described as an example.

The storage circuit 109 stores data used when the processing circuit 110 controls the entire processing by the X-ray diagnostic apparatus 1. For example, the storage circuit 109 stores a program executed by each circuit shown in FIG. Further, the storage circuit 109 stores a plurality of preset values set for each item. The preset values will be described in detail later.

The processing circuit 110 controls the operation of the entire X-ray diagnostic apparatus 1 by executing the control function 110a, the display control function 110b, the reception function 110c, and the determination function 110d. For example, the processing circuit 110 sets the shooting conditions by reading the programs corresponding to the control function 110a, the display control function 110b, the reception function 110c, and the determination function 110d from the storage circuit 109 and executing the programs. Further, for example, the processing circuit 110 controls imaging of the subject P by reading a program corresponding to the control function 110a from the storage circuit 109 and executing the program. The setting of the photographing conditions by the processing circuit 110 will be described in detail later.

Here, in the X-ray diagnostic apparatus 1 shown in FIG. 2, each processing function is stored in the storage circuit 109 in the form of a program that can be executed by a computer. The X-ray control circuit 105, the aperture control circuit 106, and the processing circuit 110 are processors that realize functions corresponding to each program by reading a program from the storage circuit 109 and executing the program. In other words, each circuit in the state where each program is read has a function corresponding to the read program. Although it has been described in FIG. 2 that the control function 110a, the display control function 110b, the reception function 110c, and the determination function 110d are realized by a single processing circuit 110, the processing circuit is a combination of a plurality of independent processors. The 110 may be configured and the function may be realized by each processor executing a program.

The word "processor" used in the above description means, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an application specific integrated circuit (ASIC), or a programmable logic device (for example,). It means a circuit such as a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA). The processor realizes the function by reading and executing the program stored in the storage circuit 109. Instead of storing the program in the storage circuit 109, the program may be directly incorporated in the circuit of the processor. In this case, the processor realizes the function by reading and executing the program embedded in the circuit. It should be noted that each processor of the present embodiment is not limited to the case where each processor is configured as a single circuit, and a plurality of independent circuits may be combined to form one processor to realize its function. Good. Further, the plurality of components in FIG. 2 may be integrated into one processor to realize the function.

The configuration of the X-ray diagnostic apparatus 1 has been described above. Under such a configuration, the X-ray diagnostic apparatus 1 according to the present application improves operability in setting imaging conditions. Specifically, the X-ray diagnostic apparatus 1 makes it possible to set the imaging conditions with one action by the processing by the processing circuit 110 described in detail below, and improves the operability in setting the imaging conditions. Hereinafter, the processing performed by the X-ray diagnostic apparatus 1 according to the first embodiment will be described in detail.

First, the display control function 110b causes the display 107 to display the condition value for each item of the shooting condition. Here, the condition value for each item of the photographing condition is an actually set photographing condition, and is managed by, for example, a storage circuit included in the X-ray control circuit 105. The display control function 110b acquires, for example, a condition value for each item by receiving a notification from the X-ray control circuit 105, and displays the acquired condition value on the display 107.

Here, the condition value to be displayed for each item by the display control function 110b will be described with reference to FIG. FIG. 3 is a diagram for explaining the display of the condition value according to the first embodiment. For example, as shown in FIG. 3, the display control function 110b has a condition value “120 kV” of item I1 indicating a tube voltage, a condition value “250 mA” of item I2 indicating a tube current, and an item indicating an X-ray irradiation time. The condition value "32 msec" of I3 is displayed on the display 107, respectively. In the following, units such as "kV", "mA", and "msec" will be omitted.

In FIG. 3, only the condition values of the item I1 indicating the tube voltage, the item I2 indicating the tube current, and the item I3 indicating the X-ray irradiation time are shown, but the display control function 110b further indicates the X-ray irradiation. It is also possible to display condition values for various items of shooting conditions such as timing and pulse width. Further, among various items of shooting conditions, the item on which the display control function 110b displays the condition value is arbitrary. That is, the display control function 110b causes the display 107 to display the condition values for at least one of the various items of the shooting conditions.

Here, the operator refers to the condition value for each item displayed on the display 107, and determines whether or not the displayed condition value is appropriate for the patient information. When it is determined that the displayed condition value is appropriate, the X-ray diagnostic apparatus 1 executes imaging under the displayed condition value. On the other hand, when it is determined that at least one of the displayed condition values is not appropriate, the X-ray diagnostic apparatus 1 accepts the setting of the condition value.

Hereinafter, the setting of the condition value will be described with reference to FIGS. 4A, 4B, 4C, 4D, 4E and 4F. 4A, 4B, 4C, 4D, 4E and 4F are diagrams for explaining the setting of the condition value according to the first embodiment. In addition, in FIG. 4A, FIG. 4B, FIG. 4C, FIG. 4D and FIG. 4E, the right hand of the operator who operates the display 107 which is a touch panel is conceptually shown.

First, the reception function 110c accepts a designation operation for designating an item for setting a condition value. For example, when the operator determines that the condition value "32" of the item I3 is not appropriate among the condition values of each item shown in FIG. 3, the reception function 110c sets the item I3 as an item for setting the condition value. Accepts the specified operation to be specified. Here, the designated operation received by the reception function 110c is, for example, an operation in which the operator touches the position of item I3 displayed on the display 107, which is a touch panel, as shown in FIG. 4A.

As an example, the reception function 110c accepts an operation in which an operator who does not touch the display 107 touches the position of the item I3 as a designated operation for designating the item I3. Further, for example, the reception function 110c is an operation in which an operator who touches a position of the display 107 other than the position of item I3 slides his / her finger while touching the display 107 to move it to the position of item I3. , Accept as a designated operation to specify item I3. In the following, the operation of sliding a finger while touching the display 107 will also be referred to as a slide operation.

When the reception function 110c accepts the designation operation for designating the item I3, the display control function 110b causes the display area R1 to be displayed on the display 107 as shown in FIG. 4B. Here, the display area R1 shown in FIG. 4B is a GUI used for setting shooting conditions. The display area R1 shown in FIG. 4B is a ring-shaped area centered on the position of item I3. Further, as shown in FIG. 4B, the condition value "32" of the item I3 is displayed in the area surrounded by the display area R1, and the operator can set the condition value of the item I3 even after the display area R1 is displayed. It can be visually recognized.

Further, a plurality of preset values are displayed in the display area R1. For example, as shown in FIG. 4B, the display area R1 has "11", "12", "23", "32", "37", "43", "54", "63", "72". And 10 preset values of "80" are displayed. Here, the preset value of the display area R1 is a plurality of preset values set in advance for the item I3 indicating the X-ray irradiation time. The preset value for item I3 is set in advance for each inspection target site and inspection content based on, for example, the condition value of the X-ray irradiation time set in the past inspection, and is stored in the storage circuit 109. The display control function 110b acquires, for example, the preset values set for the item I3 from the storage circuit 109, and causes the display 107 to display the display area R1 for displaying the acquired preset values.

Here, the preset value is set based on the content of the shooting conditions set for each item. For example, the preset value for the item I3 indicating the X-ray irradiation time is set based on the contents of various imaging conditions such as a region to be imaged, the presence or absence of a contrast medium, a tube voltage, and a tube current. As an example, when the image target part is the "lower limb", the preset value is set in the range of "11" to "80", whereas when the image target part is the "chest", X is set. Since the portion through which the line passes becomes thicker and it becomes necessary to increase the X-ray dose to be irradiated, the preset value is set in the range of "50" to "100". It should be noted that a certain preset value may be set for each item regardless of the content of the shooting conditions.

Further, the display control function 110b may be a case where the preset value is displayed in an arrangement according to the visibility by the operator. For example, as shown in FIG. 4B, since a part of the display area R1 is hidden by the operator's hand, the display control function 110b is preset at a position in the display area R1 excluding the position overlapping with the operator's hand. Display the value. Further, for example, the display control function 110b estimates the position of the display area R1 that overlaps with the operator's hand, and excludes the estimated position, depending on whether the operator performs the operation with the right hand or the left hand. Display the preset value at the position. As an example, the display control function 110b displays a GUI for receiving the setting of the dominant hand from the operator at any time before accepting the specified operation, and responds to the dominant hand of the operator set via the GUI. The position of the display area R1 that overlaps with the operator's hand is estimated.

Further, the display control function 110b may be a case where the preset value is displayed in an arrangement corresponding to the condition value of the item designated by the designated operation. For example, in FIG. 4B, the condition value of the designated item I3 is "32", and the 10 preset values set for the item I3 are in the range of "11" to "80", all of which are two digits. It is a number. In such a case, the display control function 110b can display 10 preset values, which are two-digit numbers, in the display area R1 as shown in FIG. 4B. On the other hand, for example, when the condition value of the specified item is a 4-digit number, the preset value set for this item is also often a 4-digit number as well. In such a case, if 10 preset values, which are 4-digit numbers, are displayed in the display area R1, the preset values overlap, the appearance becomes complicated, and it becomes difficult for the operator to recognize the preset values. Therefore, in order to display the preset values so as not to be complicated, the display control function 110b displays, for example, five preset values in the display area R1.

Next, the operator determines a preset value close to an appropriate value as the condition value of the item I3 among the plurality of preset values of the display area R1. For example, when it is determined that "52" is appropriate as the condition value of item I3, the operator determines that "54" is the closest preset value among the plurality of preset values shown in FIG. 4B. Next, the operator executes a slide operation of moving the finger touching the display 107 from the position shown in FIG. 4B to the position shown in FIG. 4C, and the reception function 110c selects the preset value "54". Accept operations. Then, when the preset value "54" is selected, the condition value "32" shown in the area surrounded by the display area R1 in FIG. 4B is changed to "54" at once as shown in FIG. 4C. In the following, the slide operation performed on the preset value displayed in the display area R1 for the selection operation is also described as the first slide operation. Here, the first slide operation is performed by the finger of the operator who touches the display 107 for the designated operation. That is, the designation operation and the selection operation are continuously performed.

Next, the reception function 110c accepts an adjustment operation for adjusting the preset value selected by the selection operation. For example, when the operator determines that "52" is appropriate as the condition value of item I3 and the preset value "54" is selected in the selection operation, the reception function 110c uses the selected preset value "54". Accepts an adjustment operation that reduces "2".

As an example, the operator first executes a slide operation in which the finger touching the display 107 is moved along the circumference of the display area R1 from the position shown in FIG. 4C to the position shown in FIG. 4D. .. By such a slide operation, the reception function 110c accepts an adjustment operation of reducing the preset value "54" by "1" to "53" as shown in FIG. 4D. Further, the operator executes a slide operation of moving the finger touching the display 107 from the position shown in FIG. 4D to the position shown in FIG. 4E along the circumference of the display area R1, and the reception function 110c is used. , As shown in FIG. 4E, the adjustment operation of reducing the preset value "53" by "1" to "52" is accepted.

That is, the reception function 110c adjusts the selected preset value "54" to an appropriate condition value "52" by the slide operation of sequentially moving the finger to the position shown in FIG. 4D and the position shown in FIG. 4E. Accept. In the following, the slide operation performed in the display area R1 in order to adjust the preset value selected by the selection operation is also described as the second slide operation. Here, the second slide operation is performed by the finger of the operator who has moved into the display area R1 by performing the first slide operation. That is, the selection operation and the adjustment operation are continuously performed.

Further, as shown in FIGS. 4D and 4E, the reception function 110c has a preset value selected by a second slide operation performed counterclockwise along the circumference of the display area R1 which is the shape of a ring. Accepts adjustment operations to reduce. Further, the reception function 110c accepts an adjustment operation for increasing the selected set value by a second slide operation performed clockwise along the circumference of the display area R1 which is the shape of a ring. The correspondence between the direction of the second slide operation and the increase / decrease of the set value is arbitrary.

Further, in FIGS. 4D and 4E, in the second slide operation along the circumference of the display area R1, two lines connecting the position of the operator's finger before and after the movement and the center of the display area R1 are formed. It shows the case where the set value is increased or decreased by "1" when the angle (central angle) changes by about "30 °". The correspondence between the amount of change in the central angle and the amount of change in the set value is arbitrary. Here, the values that can be set for items such as the tube current and the X-ray irradiation time may be discontinuous values (discrete values) instead of values in increments of "1" (continuous values). In such a case, the reception function 110c performs an adjustment operation for sequentially changing the selected set value to a smaller discrete value by, for example, a second slide operation performed counterclockwise along the circumference of the display area R1. Accept. Further, the reception function 110c accepts an adjustment operation for sequentially changing the selected set value to a larger discrete value by, for example, a second slide operation performed clockwise along the circumference of the display area R1.

Further, after accepting the selection operation, the display control function 110b is a case where the plurality of preset values displayed in the display area R1 are switched to a plurality of adjusted values for display. May be good. For example, the display control function 110b has "11", "12", "23", "32", "37", "43", "54", "63", "72" before accepting the selection operation. 10 preset values of "80" and "80" are displayed in the display area R1. Next, when the selection operation for selecting the preset value "54" is accepted, the display control function 110b uses "48", "49", "50", "51", "52", "53", and "54". , "55", "56", and "57" are displayed in the display area R1 as a plurality of values adjusted with the preset value "54". Then, the operator executes a second slide operation of moving the finger to the position where an appropriate condition value (for example, "52") is displayed, and the reception function 110c sets the selected preset value "54". Accepts the adjustment operation to adjust to "52". That is, the display control function 110b switches the plurality of preset values in the display area R1 to the plurality of adjusted values of the selected preset values and displays them, so that the second slide performed by the operator for the adjustment operation. It may be the case to support the operation.

Next, the second slide operation is completed, and the determination function 110d determines the condition value of the item designated by the designated operation as the preset value after the adjustment by the adjustment operation. Here, the second slide operation ends, for example, when the operator releases his finger from the display 107. For example, when the second slide operation is completed in the state shown in FIG. 4E, the determination function 110d adjusts the condition value of the designated item I3 to the preset value “52” after the adjustment operation, as shown in FIG. 4F. To decide. Further, the determination function 110d notifies the X-ray control circuit 105 that the condition value of the designated item I3 has been determined to be the adjusted preset value “52”. Further, when the condition value of the designated item I3 is determined, the display control function 110b ends the display of the display area R1.

When the setting of the condition value is completed, the control function 110a includes the high voltage generator 101, the X-ray tube 102, the X-ray movable throttle 103, the X-ray detector 104, the X-ray control circuit 105, and the radiograph control circuit 106.

Specifically, the control function 110a controls the operation of the high voltage generator 101 by controlling the X-ray control circuit 105 when it receives a request to start photographing, and the X-ray tube 102 under the set condition value. Is supplied with a high voltage to expose X-rays. Further, the control function 110a controls the operation of the X-ray movable diaphragm 103 by controlling the diaphragm control circuit 106, and controls the X-ray irradiation region. Further, the control function 110a detects X-rays transmitted through the subject P by controlling the operation of the X-ray detector 104, and collects image data. Further, the control function 110a controls an image processing circuit (not shown), executes various image processing on the collected image data, and generates an X-ray image for display. Further, the display control function 110b displays the generated X-ray image for display on the display 107.

Next, an example of the processing procedure by the X-ray diagnostic apparatus 1 will be described with reference to FIG. FIG. 5 is a flowchart for explaining a series of processes of the X-ray diagnostic apparatus 1 according to the first embodiment. Step S102 is a step corresponding to the control function 110a. Step S101 and step S104 are steps corresponding to the display control function 110b. Step S103, step S105, and step S106 are steps corresponding to the reception function 110c. Step S107 is a step corresponding to the determination function 110d.

First, the processing circuit 110 displays the condition value for each item of the shooting condition on the display 107 (step S101), and receives an input operation from the operator who refers to the condition value to set the shooting condition. (Step S102). When setting the shooting conditions (affirmation in step S102), the processing circuit 110 receives from the operator a designation operation for designating the items to be set among the shooting condition items displayed on the display 107 (step S103).

When the designated operation is accepted, the processing circuit 110 displays a display area R1 for displaying a plurality of preset values for the designated item (step S104), and a plurality of presets are performed by the first slide operation continuous with the designated operation. A selection operation for selecting one of the values is accepted (step S105). Next, the processing circuit 110 accepts an adjustment operation for adjusting the preset value selected by the selection operation by the second slide operation continuous with the first slide operation (step S106). Then, upon completion of the second slide operation, the processing circuit 110 determines the preset value adjusted by the adjustment operation as a condition value (step S107), and proceeds to step S101 again. If the imaging conditions are not set (denial in step S102), the processing circuit 110 ends the processing.

As described above, according to the first embodiment, the display control function 110b displays the condition value for each item of the shooting condition and the display area R1 for displaying a plurality of preset values set in advance for each item 107. To display. The reception function 110c accepts a selection operation for selecting one of a plurality of preset values by the first slide operation on the preset value in the display area R1 in succession with the designation operation for designating the item, and the first slide operation. The adjustment operation for adjusting the preset value selected by the selection operation is accepted by the second slide operation consecutively with. Upon completion of the second slide operation, the determination function 110d determines the condition value of the item designated by the designated operation as the preset value adjusted by the adjustment operation. Therefore, the X-ray diagnostic apparatus 1 according to the first embodiment enables the operator to set the condition value between the time when the operator touches the display 107 with his / her finger and the time when the display 107 is released, and improves the operability in setting the imaging condition. Can be improved. That is, the X-ray diagnostic apparatus 1 enables one-action condition setting and can improve operability in setting imaging conditions.

Further, according to the first embodiment, the reception function 110c accepts a selection operation for selecting one of a plurality of preset values, and receives an adjustment operation for adjusting the preset value selected by the selection operation. Therefore, the X-ray diagnostic apparatus 1 according to the first embodiment can perform one action without performing 20 tap operations or the like when increasing the condition value "32" of the X-ray irradiation time to "52", for example. It is possible to make settings and improve operability when changing the shooting condition settings.

In addition, the X-ray diagnostic apparatus 1 according to the first embodiment accepts the setting of imaging conditions in one action on a console that integrates various functions such as setting and management of imaging conditions, collection, display, and management of image data. .. Therefore, the X-ray diagnostic apparatus 1 according to the first embodiment can easily set the imaging conditions and reduce the installation location of the console without using the hardware switch of the operation console.

(Second Embodiment)
In the first embodiment described above, a case where shooting conditions are set based on an operation on a GUI including only a display area for displaying a plurality of preset values has been described. On the other hand, in the second embodiment, a case where the shooting condition is set based on the operation for the GUI including the display area and the change area for accepting the change operation of the condition value will be described. The X-ray diagnostic apparatus 1 according to the second embodiment has the same configuration as the X-ray diagnostic apparatus 1 according to the first embodiment shown in FIG. 2, and is processed by the display control function 110b and the reception function 110c. Some are different. Therefore, the points having the same configurations as those described in the first embodiment are designated by the same reference numerals as those in FIG. 2, and the description thereof will be omitted.

First, the display area and the change area to be displayed by the display control function 110b according to the second embodiment will be described with reference to FIGS. 6A and 6B. 6A and 6B are diagrams for explaining the display area and the change area according to the second embodiment. First, the display control function 110b causes the display 107 to display the condition value for each item of the shooting condition. For example, as shown in FIG. 6A, the display control function 110b has a condition value “250” of item I4 indicating a tube current, a condition value “0.032” of item I5 indicating an X-ray irradiation time, and subjects P and X. The condition value "120" of the item I6 indicating the distance (Patient-Imager Distance: PID) to the line detector 104 and the condition value "120" of the item I7 indicating the thickness of the subject P are displayed.

Next, the reception function 110c receives a designation operation for designating the item to be set from the operator who has referred to the condition value of each item. For example, as shown in FIG. 6A, the reception function 110c sets the shooting conditions by accepting the operation of touching the position of item I5 in the display 107 which is a touch panel, and is the item I5 indicating the X-ray irradiation time. Accepts the specified operation to specify.

When the designation operation for designating the item I5 is accepted, the display control function 110b causes the display 107 to display the display area R1 and the change area R2 shown in FIG. 6B. Here, the display area R1 and the change area R2 shown in FIG. 6B are GUIs used for setting shooting conditions. Further, as shown in FIG. 6B, the display area R1 and the change area R2 are ring-shaped areas, and the display area R1 is arranged so as to surround the change area R2. That is, the GUI according to the second embodiment has a two-wheel shape including a display area R1 which is an outer ring and a change area R2 which is an inner ring. Here, as shown in FIG. 6B, the display control function 110b transparently displays the portion excluding the outline of the GUI so that the operator can visually recognize the condition value of each item even after the GUI is displayed. it can.

Further, the display control function 110b displays a plurality of preset values preset for the item I5 in the display area R1 shown in FIG. 6B. Here, the ten preset values of "11", "12", "23", "32", "37", "43", "54", "63", "72" and "80" are "0.011", "0.012", "0.023", "0.032", "0.037", "0.043", "0.054", "0.063", respectively. It means "0.072" and "0.080". That is, in the display area R1, only the number of the second decimal place and the number of the third decimal place of each preset value are displayed. Here, the number of ones digit, the decimal point, and the number of decimal places of each preset value are less necessary as a judgment material when the operator selects a preset value, and by omitting these and displaying them. The display control function 110b can avoid complicated display of preset values in the display area R1.

Here, the reception function 110c according to the second embodiment receives at least one of an operation on the display area R1 which is the outer ring and an operation on the change area R2 which is the inner ring from the operator. First, a case where the reception function 110c accepts an operation for the change area R2 will be described with reference to FIGS. 7A, 7B, and 7C. 7A, 7B and 7C are diagrams for explaining the modified region according to the second embodiment.

For example, the reception function 110c accepts a change operation for changing the condition value "0.032" of the item I5 designated by the designated operation by the slide operation in the change area R2. As an example, when the operator determines that "0.034" is appropriate as the condition value of item I5, the operator moves the finger in the state of touching the display 107 from the position shown in FIG. 6B to the position shown in FIG. 7A. Until, the slide operation of moving along the circumference of the change area R2 is executed. By such a slide operation, as shown in FIG. 7A, the reception function 110c accepts a change operation in which the condition value "0.032" is increased by "0.001" to "0.033". Further, the operator executes a slide operation of moving the finger touching the display 107 from the position shown in FIG. 7A to the position shown in FIG. 7B along the circumference of the change area R2. By such a slide operation, as shown in FIG. 7B, the reception function 110c accepts a change operation in which the condition value "0.033" is increased by "0.001" to "0.034". That is, by the slide operation of sequentially moving the finger to the position shown in FIG. 7A and the position shown in FIG. 7B, the reception function 110c sets the specified condition value “0.032” of the item I5 to an appropriate condition value “0.034”. Accepts the change operation to change to.

Then, as shown in FIG. 7C, for example, the determination function 110d determines the changed condition value to "0.034" when the operator releases the finger from the display 107. Further, the determination function 110d notifies the X-ray control circuit 105 that the condition value of the designated item I5 has been determined to be "0.034". When the condition value of the designated item I5 is determined, the display control function 110b ends the display of the display area R1 and the change area R2.

In the following, in order to change the condition value of the item designated by the designated operation, the slide operation performed in the change area R2 is also described as the third slide operation. Here, the third slide operation is performed by the finger of the operator who touches the display 107 by performing the designated operation. That is, the designation operation and the change operation are continuously performed. Further, since the display control function 110b displays the GUI transparently, the operator can visually recognize the condition value of each item even after the GUI is displayed. Therefore, as shown in FIGS. 7A and 7B, the operator performs the third slide operation in the change area R2 while confirming the condition value (current condition value) of the item I5 changed by the change operation. Can be done.

Further, as shown in FIGS. 7A and 7B, the reception function 110c is changed to increase the condition value by a third slide operation performed clockwise along the circumference of the change region R2 which is the shape of a ring. Accept operations. Further, the reception function 110c accepts a change operation for reducing the condition value by a third slide operation performed counterclockwise along the circumference of the change region R2 which is the shape of a ring. The correspondence between the direction of the third slide operation and the increase / decrease of the condition value is arbitrary.

Further, in FIGS. 7A and 7B, in the third slide operation along the circumference of the change area R2, two lines connecting the position of the operator's finger before and after the movement and the center of the change area R2 are formed. It shows the case where the set value is increased or decreased by "1" when the angle (central angle) changes by about "30 °". The correspondence between the amount of change in the central angle and the amount of change in the condition value is arbitrary. Here, when the condition value that can be set for the specified item is a discrete value, the reception function 110c is selected by, for example, a third slide operation performed clockwise along the circumference of the change area R2. Accepts a change operation that sequentially changes the condition value of an item to a larger discrete value. Further, the reception function 110c is a change operation for sequentially changing the condition value of the selected item to a smaller discrete value by, for example, a third slide operation performed counterclockwise along the circumference of the change area R2. Accept.

Next, a case where the reception function 110c accepts an operation for the display area R1 will be described with reference to FIGS. 8A, 8B, and 8C. 8A, 8B, and 8C are diagrams for explaining the display area R1 according to the second embodiment.

For example, the display area R1 and the change area R2 shown in FIG. 6B are displayed by the designation operation for specifying the item I5, and the operator sets an appropriate value as the condition value of the item I5 among the plurality of preset values of the display area R1. Determine close preset values. For example, when "0.053" is appropriate as the condition value of item I5, "54" is the closest preset value among the plurality of preset values shown in FIG. 8A. In such a case, the operator executes the first slide operation of moving the finger in the state of touching the display 107 from the position shown in FIG. 6B to the position shown in FIG. 8A, and the reception function 110c sets the preset value "54". Accepts the selection operation to select. Then, as shown in FIGS. 6B and 8A, the condition value “0.032” of the item I5 is changed to the preset value “0.054” at once.

Here, for example, as shown in FIG. 8A, the reception function 110c is the display area R1 which is the outer ring without performing the third slide operation along the circumference of the change area R2 which is the inner ring. When the first slide operation for the preset value of is performed, the selection operation for selecting the preset value is accepted. Alternatively, the reception function 110c is the first with respect to the preset value of the display area R1 which is the outer ring, regardless of whether or not the third slide operation along the circumference of the change area R2 which is the inner ring is performed. Accepts a selection operation to select a preset value when the slide operation of is performed.

When the third slide operation in the change area R2 is performed and the change operation for changing the condition value is accepted, the display control function 110b is a case where the preset value corresponding to the changed condition value is displayed. May be good. For example, when the condition value of item I5 is "0.032", the display control function 110b displays preset values set in the range of "11" to "80" as shown in FIG. 6B. Here, when the condition value of item I5 is changed and the condition value of item I5 becomes "0.075", the display control function 110b sets a preset value set in the range of "50" to "100". indicate. That is, the preset value of the display area R1 may be dynamically changed according to the current condition value of the specified item.

Next, the reception function 110c accepts an adjustment operation for adjusting the preset value "0.054" selected by the selection operation. For example, the operator executes a second slide operation of moving the finger touching the display 107 from the position shown in FIG. 8A to the position shown in FIG. 8B, and the reception function 110c sets the preset value “0.054”. Is accepted to reduce "0.001".

Then, the determination function 110d determines the condition value of the item designated by the designated operation at the end of the second slide operation. For example, in the state shown in FIG. 8B, the second slide operation is completed when the operator releases the finger from the display 107, and the determination function 110d adjusts the condition value of item I5 by the adjustment operation as shown in FIG. 8C. The preset value after adjustment is determined to be "0.053". Further, the determination function 110d notifies the X-ray control circuit 105 that the condition value of the designated item I5 has been determined to be "0.053", and sets the condition value "0.053". When the condition value of the designated item I5 is determined, the display control function 110b ends the display of the display area R1 and the change area R2.

Next, an example of the processing procedure by the X-ray diagnostic apparatus 1 will be described with reference to FIG. FIG. 9 is a flowchart for explaining a series of processes of the X-ray diagnostic apparatus 1 according to the second embodiment. Step S202 is a step corresponding to the control function 110a. Step S201 and step S204 are steps corresponding to the display control function 110b. Step S203, step S205, step S206 and step S207 are steps corresponding to the reception function 110c. Step S208 is a step corresponding to the determination function 110d.

First, the processing circuit 110 displays the condition value for each item of the shooting condition on the display 107 (step S201), and receives an input operation from the operator who refers to the condition value to set the shooting condition. (Step S202). When setting the shooting conditions (affirmation in step S202), the processing circuit 110 receives from the operator a designation operation for designating the item to be set among the shooting conditions displayed on the display 107 (step S203).

When the designated operation is accepted, the processing circuit 110 displays a display area R1 for displaying a plurality of preset values for the designated item and a change area R2 for accepting the change operation (step S204). Here, the processing circuit 110 determines whether or not a selection operation for selecting one of a plurality of preset values has been accepted by the first slide operation continuous with the designated operation (step S205).

When the selection operation is not accepted (denial in step S205), the processing circuit 110 changes the condition value of the item specified by the designated operation by the third slide operation continuous with the designated operation in the change area R2. (Step S206), after determining the changed condition value, the process proceeds to step S201 again. On the other hand, when the selection operation is accepted (step S205 affirmative), the processing circuit 110 accepts the adjustment operation for adjusting the preset value selected by the selection operation by the second slide operation continuous with the first slide operation. (Step S207). Then, upon completion of the second slide operation, the processing circuit 110 determines the preset value adjusted by the adjustment operation as a condition value (step S208), and proceeds to step S201 again. If the shooting conditions are not set (denial in step S202), the processing circuit 110 ends the processing.

As described above, according to the second embodiment, the display control function 110b sets the display area R1 for displaying a plurality of preset values set in advance for each item and the condition value of the item designated by the designated operation. The change area R2 for accepting the change operation to be changed is displayed. The reception function 110c accepts a selection operation for selecting one of a plurality of preset values by the first slide operation on the preset value in the display area R1 in succession with the designation operation for designating the item, and the first slide operation. The adjustment operation for adjusting the preset value selected by the selection operation is accepted by the second slide operation consecutively with. Further, the reception function 110c receives a change operation for changing the condition value of the item selected by the designated operation by the third slide operation in the change area R2 in succession with the designated operation.

Therefore, the X-ray diagnostic apparatus 1 according to the second embodiment can accept the setting of the condition value of the item designated by the designated operation in the display area R1 or the change area R2. For example, when the condition value is changed significantly, such as when the condition value is changed from "0.032" to "0.053", the X-ray diagnostic apparatus 1 sets the preset value by the operation in the display area R1. It enables quick setting of condition values via. Further, for example, when the condition value is changed to a small width, such as when the condition value is changed from "0.032" to "0.034", the X-ray diagnostic apparatus 1 operates the condition in the change area R2. It enables simple setting to change the value directly. In this way, the X-ray diagnostic apparatus 1 accepts the setting of the condition value in the two-wheel GUI of the display area R1 and the change area R2, so that the condition value can be set by a method as needed. It is possible to improve the operability in setting the shooting conditions.

(Third Embodiment)
In the above-described embodiment, the setting of the condition value based on the operation for the GUI including the display area R1 or the GUI including the display area R1 and the change area R2 has been described. On the other hand, in the third embodiment, in addition to the above-mentioned setting of the condition value based on the operation for the GUI, the case where the condition value is set based on the flick operation for the condition value for each item will be described. The X-ray diagnostic apparatus 1 according to the third embodiment has the same configuration as the X-ray diagnostic apparatus 1 according to the first embodiment shown in FIG. 2, and a part of the processing by the reception function 110c is different. .. Therefore, the points having the same configurations as those described in the first embodiment are designated by the same reference numerals as those in FIG. 2, and the description thereof will be omitted.

The setting of the condition value by the flick operation will be described with reference to FIGS. 10A and 10B. 10A and 10B are diagrams for explaining the flick operation according to the third embodiment. First, the display control function 110b causes the display 107 to display the condition value for each item of the shooting condition. For example, as shown in FIG. 10A, the display control function 110b has a condition value “250” of item I4 indicating a tube current, a condition value “0.032” of item I5 indicating an X-ray irradiation time, and an item I6 indicating PID. The condition value "120" of the above and the condition value "120" of the item I7 indicating the thickness of the subject P are displayed.

Next, the reception function 110c receives a flick operation for the item to be set from the operator who has referred to the condition value of each item. For example, when it is determined that "0.033" is appropriate for the condition value of item I5 shown in FIG. 10A, the operator touches the position of item I5 of the display 107 with a finger as shown in FIG. 10A. Next, as shown in FIG. 10B, the operator quickly moves the finger touching the display 107 upward from the position of item I5. In the following, as shown in FIG. 10B, the operation of quickly moving the finger touching the display 107 or the operation of flipping the finger on the display 107 is simply referred to as a flick operation.

Then, the reception function 110c accepts a change operation for increasing the condition value of the item I5, which is the target of the flick operation, by "0.001" by the flick operation shown in FIG. 10B. Further, for example, when the operator performs a flick operation for quickly moving the finger touching the position of item I5 on the display 107 downward from the position of item I5, the reception function 110c is the target of the flick operation. Accepts a change operation that reduces the condition value of item I5 by "0.001".

As described above, according to the third embodiment, the reception function 110c accepts a change operation for changing the condition value of the item targeted for the flick operation by flicking the condition value for each item. Therefore, the X-ray diagnostic apparatus 1 according to the third embodiment has a small condition value, for example, when the X-ray diagnostic apparatus 1 changes the condition value from "0.032" to "0.033". When changing, a simple setting that directly changes the condition value can be made by flicking. Further, the X-ray diagnostic apparatus 1 can easily adjust the set condition value by flicking when the condition value is set by the operation in the display area R1, for example.

(Fourth Embodiment)
In the above-described embodiment, the case where the input circuit 108 has the display 107 which is a touch panel and the condition value is set based on the operation on the display 107 has been described. On the other hand, in the fourth embodiment, a case where the condition value is set based on the operation of the mouse included in the input circuit 108 will be described. The X-ray diagnostic apparatus 1 according to the fourth embodiment has the same configuration as the X-ray diagnostic apparatus 1 according to the first embodiment shown in FIG. 2, and a part of the processing by the reception function 110c is different. .. Therefore, the points having the same configurations as those described in the first embodiment are designated by the same reference numerals as those in FIG. 2, and the description thereof will be omitted.

First, the display control function 110b displays the condition values of each item on the display 107, for example, as shown in FIG. Here, the operator moves the mouse cursor to the position of the item for which the condition value is set and presses the mouse button, and the reception function 110c accepts the designated operation for designating the item. When the designated operation is accepted, the display control function 110b causes the display 107 to display the display area R1 for displaying a plurality of preset values.

Next, the operator determines a preset value close to an appropriate value as the condition value of the specified item among the plurality of preset values, and the mouse cursor is held down to the position of the determined preset value while the mouse button is pressed. To move. Then, the reception function 110c accepts a selection operation for selecting the preset value on which the mouse cursor is superimposed from the plurality of preset values in the display area R1. Further, the operator moves the mouse cursor in the display area R1 while pressing the mouse button, and the reception function 110c accepts an adjustment operation for adjusting the preset value selected by the selection operation. Then, when the operator releases the finger from the mouse button, the determination function 110d determines the condition value of the item designated by the designated operation as the preset value adjusted by the adjustment operation.

As described above, the X-ray diagnostic apparatus 1 can set the condition value by operating the mouse as well as operating the touch panel. For example, the operation of pressing a mouse button corresponds to the operation of touching a touch panel. Further, for example, the operation of moving the mouse cursor while pressing the mouse button corresponds to the operation of moving the finger while touching the touch panel. That is, by moving the mouse cursor while the operator presses the mouse button, the reception function 110c has various types including the first slide operation, the second slide operation, and the third slide operation described above. It can accept input of slide operation. Further, for example, the operation of releasing the finger from the mouse button corresponds to the operation of releasing the finger from the touch panel.

That is, ON operation (operation to specify the position on the screen such as touch panel touch operation and mouse button press operation), slide operation (operation to move the finger while touching the touch panel and mouse button press state). As long as it is possible to perform operations such as moving the mouse cursor while moving the input means) and OFF operations (operations that end the slide operation such as the operation of releasing the finger from the touch panel and the operation of releasing the finger from the mouse button). The device included in the input circuit 108 is arbitrary. Then, the X-ray diagnostic apparatus 1 according to the fourth embodiment enables the setting of the condition value by one action via an arbitrary device, and can improve the operability in the setting of the imaging condition.

(Fifth Embodiment)
By the way, although the first to fourth embodiments have been described so far, various different embodiments may be implemented in addition to the above-described embodiments.

In the above-described embodiment, the display control function 110b displays a display area R1 for displaying a plurality of preset values set for the item specified by the designated operation when the reception function 110c accepts the designated operation. explained. However, the embodiment is not limited to this, and for example, the display control function 110b may display the display area R1 in advance regardless of whether or not the reception function 110c has received the designated operation. ..

Further, in the above-described embodiment, the case where the display region R1 has the shape of a ring has been described. However, the embodiment is not limited to this. Here, an example of the shape of the display area R1 will be described with reference to FIG. FIG. 11 is a diagram for explaining the display area R1 according to the fifth embodiment. For example, the display control function 110b first displays the condition value of each item on the display 107 as shown in FIG. 3, and the reception function 110c accepts the designation operation for designating the item I3. Here, as shown in FIG. 11, the display control function 110b displays the display area R1 which is a part of the shape of the ring. Further, the reception function 110c accepts a selection operation for selecting a preset value by a first slide operation on the preset value of the display area R1 shown in FIG. Further, the reception function 110c accepts an adjustment operation for adjusting the selected preset value by the second slide operation in the display area R1 shown in FIG. Then, the determination function 110d determines the condition value of the item I3 to the adjusted preset value.

As described above, even if the shape of the display area R1 is the shape shown in FIG. 11, the X-ray diagnostic apparatus 1 sets the condition value in the same manner as when the shape of the display area R1 is the shape of a circle. be able to. That is, the shape of the display region R1 can be variously deformed including the shape shown in FIG. 11 and the shape of an annulus, and may be, for example, a semicircular shape or a rod shape. Further, the same modification is possible for the change area R2.

Further, in the above-described embodiment, the case where the display area R1 is displayed at the position of the designated item when there is a designation operation for the item of the shooting condition has been described, but the embodiment is not limited to this. Absent. For example, the display control function 110b may display the display area R1 at a position that does not overlap with the display of the condition value of each item.

Here, the pass band of the filter is set as a constant frequency range for the purpose of removing noise, for example. The sound velocity is a velocity (sound velocity value) set as the average sound velocity of the body tissue of the subject to be imaged. Further, the speed range is a value that determines which range of speed is to be observed in the Doppler mode, and for example, the maximum speed and the minimum speed are set. Further, the gain and the color gain are values that determine the brightness and color of the entire image. Then, the condition value for each item of the collection condition of the ultrasonic image data can be set in the same manner as the condition value for each item of the imaging condition described above.

Further, in the above-described embodiment, the setting of medical image data collection conditions (particularly, imaging conditions such as tube current, tube voltage, and X-ray irradiation time) has been described, but the embodiment is not limited to this. .. For example, the medical image diagnostic apparatus according to the embodiment processes conditions, window width, window level, etc. attached to image data such as SID (Source Image receptor Distance), PID, and subject thickness (thickness of subject P). The condition items can also be set in the same manner as the condition values for each of the shooting condition items described above. Here, although the conditions attached to the image data such as SID, PID, and subject thickness, and the processing conditions such as window width and window level are not directly related to the collection of image data, the image is displayed appropriately after shooting. It is a parameter used to do. That is, the medical image diagnostic apparatus according to the embodiment makes it possible to set conditions related to various processes including collection, management, and display of image data in the GUI described above with one action.

Further, in the above-described embodiment, the case where the medical image diagnostic apparatus sets the collection condition of the medical image data has been described as an example, but the embodiment is not limited to this. For example, a display control function 110b for displaying a condition value for each item and a display area R1 for displaying a plurality of preset values set in advance for each item on the display 107, and a designation operation for designating the item are displayed in succession. A selection operation for selecting one of a plurality of preset values is accepted by the first slide operation on the preset value of the area R1, and the preset value selected by the selection operation by the second slide operation continuous with the first slide operation. The reception function 110c that accepts the adjustment operation for adjusting the adjustment operation and the determination function 110d that determines the condition value of the item specified by the specified operation as the preset value after the adjustment by the adjustment operation are executed by the end of the second slide operation. The display device may have the processing circuit 110. In such a case, the display device makes it possible to set the condition value for each item with one action by executing the processing circuit 110. Further, such a display device makes it possible to set various conditions with one action, not limited to the conditions related to the processing by the medical image diagnosis device.
