A conversion and TV format conversion are performed and displayed on the large screen monitor 7a. In addition, the display circuit 7 is arranged away from the input interface circuit 12, and displays an operation screen g2 visually recognized by the operator on the large screen monitor 7a based on the operation screen data. The large-screen monitor 7a may be called with another name such as “monitor” or “display”, and the modifier meaning “large” is not necessarily added. Further, the large screen monitor 7a is not limited to a case where a single screen is large, and a large screen may be formed by arranging a plurality of normal screens close to each other. Further, the large screen monitor 7a is not necessarily a large screen, and may be a screen having a size that can be used for a catheter procedure or the like.

  On the other hand, the mechanism driving unit 10 includes an imaging system moving mechanism driving unit 101 that supplies driving signals to various moving mechanism units provided in the holding device 8 in order to move the imaging system in a desired direction, and a subject 150.

  Next, the structure of the holding device 8 and the bed part 9 and the movement or rotation of each unit constituting them will be described with reference to FIG. FIG. 2 shows a holding device 8 having a C-arm attached to the ends of the X-ray generator 2 and the X-ray detector 3 (imaging system) as a holding unit 81 and a top plate 91 on which a subject 150 is placed. In this figure, in order to facilitate the following description, the body axis direction of the subject 150 (that is, the longitudinal direction of the top 91) is the y axis, and the holding unit (C arm). The center axis (rotation axis) direction of the stand 83 that holds 81 is the z axis, and the y axis and the direction orthogonal to the z axis are the x axis.

  That is, the holding unit 81 having the X-ray generation unit 2 attached to one end (lower end) and the X-ray detector 3 attached to the other end (upper end) is provided with a holding unit holder 82. The holding portion 81 is attached to the side surface of the holding portion holder 82 so as to be slidable in the direction of the arrow a. On the other hand, the holding portion holder 82 is attached to the stand 83 so as to be rotatable in the direction of the arrow b. As the holding portion holder 82 rotates, the holding portion 81 also rotates about the x axis. An imaging system is attached to the end of the holding portion 81 so as to be slidable in the e direction. Then, the imaging system attached to the end of the holding unit 81 is placed on the top 91 by sliding the holding unit 81 in the a direction, rotating the holding unit holder 82 in the b direction, and sliding the imaging system in the e direction. The target 150 can be set at an arbitrary position and direction.

  On the other hand, one end portion of the floor turning arm 84 disposed on the floor surface 160 is attached to the floor surface 160 so as to be rotatable about a rotation axis z1 (first rotation axis). At the other end, a stand 83 is attached so as to be rotatable about a rotation axis z2 (second rotation axis). In this case, both the rotation axis z1 of the floor turning arm 84 and the rotation axis z2 of the stand 83 are set with respect to the z direction.

The rotation angle with respect to the direction, the rotation angle with respect to the c direction of the stand 83, and the slide movement distance of the imaging system with respect to the holding unit 81 are uniquely determined.

  Accordingly, in order to move or rotate the holding unit 81, the holding unit holder 82, the stand 83, and the floor turning arm 84 in a predetermined direction, the various moving mechanism units of the holding device 8 from the imaging system moving mechanism driving unit 101 of the mechanism driving unit 10 are used. (I.e., a holding unit slide mechanism unit that slides the holding unit 81, a holding unit holder rotating mechanism unit that rotates the holding unit holder 82 in the b direction, a stand rotating mechanism unit that rotates the stand 83 in the c direction, A drive signal supplied to each of the floor swing arm rotating mechanism unit that rotates the floor swing arm 84 in the d direction and the imaging system slide mechanism unit that slides the imaging system in the e direction is detected (for example, the number of drive pulses is determined). It is possible to detect the position information of the imaging system by counting.

A mechanism is provided. Here, the horizontal width along the x-axis of the top plate 91 is different in three stages of the subject 150 on the foot side, the torso side, and the head side, and becomes shorter toward the head side. Further, as shown in FIG. 3, a hardware console 12H and a tablet terminal 12T, which are a part of the input interface circuit 12, are attached to one side of the top plate 91. A large screen monitor 7a capable of displaying the medical image g1 and the operation screen g2 is disposed obliquely above the other side of the top plate 91. A first camera 13 for photographing the hardware console 12H and the tablet terminal 12T is disposed above the large screen monitor 7a. Below the top plate 91, a foot switch 12F which is a part of the input interface circuit 12 is arranged. A second camera 14 for taking an image of the foot switch 12F is disposed in the grip portion of the foot switch 12F. The first camera 13 is not limited to the upper part of the large screen monitor 7a, and may be arranged on the ceiling of the examination room. Or you may arrange | position the 1st camera 13 in the vicinity of the hardware console 12H and the tablet terminal 12T, as shown in FIG. Alternatively, the camera 13a of the tablet terminal 12T may be used as the first camera 13, and the hardware console 12H and the tablet terminal 12T may be photographed by attaching a mirror (not shown). As shown in FIG. 5, the second camera 14 is disposed in the grip portion 12Fg facing the pedal of the foot switch 12F. However, the second camera 14 is not limited to this, and the foot switch 12F may be disposed at other positions as long as it can be photographed. It doesn't matter.

  The storage circuit 11 includes a memory for recording electrical information such as an HDD (Hard Disk Drive), and peripheral circuits such as a memory controller and a memory interface associated with the memory. The storage circuit 11 stores a program executed by the control circuit 15 and various information used for executing the program. As various types of information, for example, as shown in FIGS. 6A to 16, image information L1 to L3 of each layer for generating the operation screen g2, layout information 111 indicating a layout such as buttons operated by the operator, and buttons The allocation information 112, 112a, 112a1, 112a2, and 112b indicating the functions allocated to and the like can be used as appropriate. The term “operation screen” may be called “operation image”.

  As the image information of each layer, as shown in FIGS. 6A to 6C, input I / F image information L1, user operation image information L2, and operation auxiliary image information L3 can be used as appropriate. The user operation image information L2 is superimposed on the input I / F image information L1, and the operation auxiliary image information L3 is superimposed on the user operation image information L2, thereby generating an operation screen g2. Note that at least the input I / F image information L1 is used to generate the operation screen g2, and the user operation image information L2 and the operation auxiliary image information L3 are additionally used according to the operation situation. As the user operation image information L2, as shown in FIG. 6A, image information including a simulated human body part image representing a hand or a foot may be stored in the storage circuit 11. Alternatively, as the user operation image information L2, image information including a human body part image extracted from a live image as an output of the first camera 13 or the second camera 14 as shown in FIG. 6B or 6C may be used. Good. The human body part image in the user operation image information L2 illustrated in FIG. 6B represents the hand extracted from the live image of the first camera 13 from the wrist of the operator to the fingertip. The human body part image in the user operation image information L2 illustrated in FIG. 6C represents only a finger used for the operation as a hand extracted from the live image of the first camera 13. Note that the finger shown in FIG. 6C has an enlarged portion of the finger shown in FIG. 6B in order to improve visibility. However, the present invention is not limited thereto, and the finger shown in FIG. 6C may be the same size as the finger shown in FIG. 6B. Further, as the user operation image information L2, although not shown, image information including a human body part image representing the shoe of the operator may be used as a foot extracted from the live image of the second camera 14. The names “input I / F image information”, “user operation image information”, and “operation auxiliary image information” of the image information L1 to L3 are names for convenience of explanation, and may be changed as appropriate. . For example, “input I / F image information”, “user operation image information”, and “operation auxiliary image information” may be called “first image information”, “second image information”, and “third image information”, respectively. Good. Alternatively, “input I / F image information”, “user operation image information”, and “operation auxiliary image information” may be called “lower layer information”, “intermediate layer information”, and “upper layer information”, respectively. In addition, the superimposed display may be expressed as an overlay display.

  As shown in FIG. 7, the input I / F image information L1 is first image information representing the operation surfaces of the hardware console 12H, the tablet terminal 12T, and the foot switch 12F as the input interface circuit 12, and is stored in advance. Has been. As the input I / F image information L1, in the case of the hardware console 12H and the foot switch 12F, for example, an appropriately abstracted image may be used, or an external image taken in advance may be used. As the input I / F image information L1, in the case of the tablet terminal 12T, for example, an abstracted image as described above may be used, or information on a display screen of the tablet terminal 12T may be used. Alternatively, the button I / F image information L1 may be generated by storing the button pattern information for each function and arranging the button pattern information according to the function assignment.

  In addition to this, as the input I / F image information L1, as shown in FIG. 8, function allocation is performed corresponding to each page Pg1 to Pg4 based on each page Pg1 to Pg4 of the layout information 111 and the allocation information 112. It may be changed. The allocation information 112 is information in which functions and operation assistance information are allocated for each button ID, and the allocation contents are different for each page. In this case, as shown in FIG. 9, for example, an operation screen g2 including the input I / F image information L1 corresponding to the page Pg1 and an operation screen g2 including the input I / F image information L1 corresponding to the page Pg4 are switched. It can be displayed. The pages Pg1 to Pg4 mentioned here may be, for example, the allocation information 112 corresponding to a part such as a brain, heart, or leg, or may be the allocation information 112 corresponding to a protocol that is an examination unit. In this case, it is possible to realize function assignment linked to the part or protocol.

  The layout information 111 is information indicating the layout of buttons and the like arranged on the operation surface of the input interface circuit 12, and indicates the arrangement of button IDs for identifying each button and the like. In the case of the example shown in FIG. 10, the buttons and the like arranged on the operation surface of the hardware console 12H and the button ID of the layout information 111 individually correspond to each other. In this example, the layout information 111 associates a switch such as a button arranged on the operation surface and its vicinity region with a button ID. The button ID corresponding to the switch such as a button may be appropriately called a dial ID or a lever ID for a switch other than the button such as a dial or a lever. Alternatively, “button”, “dial”, and “lever” may be referred to as “button switch”, “dial switch”, and “lever switch”, respectively. Further, the “button”, “dial”, and “lever” may be called “switches”. That is, the term “switch” includes “button”, “dial”, “lever”, and the like.

  The allocation information 112 is information in which functions and operation assistance information are allocated for each button ID, and a function (Auto.Pos) for switching to other allocation information 113 may be set as shown in FIG. The other assignment information 113 is, for example, information in which numeric input and operation assistance information are assigned for each button ID. In this case, the operation of the AutoPos button can be switched between assigning numeric input to the button and assigning function execution to the button.

  As the allocation information 112, as shown in FIG. 12, as shown in FIG. 11, a function (function allocation) to be switched to allocation information 112a indicating allocation of other functions may be set. The allocation information 112a is information in which the second function and the operation assistance information are allocated for each button ID, for example. In this case, for example, according to the on / off state of the button with the button ID “bt27” to which the function switching is assigned, the first function assignment information 112 and the second function which is a function different from the first function are included. The allocation information 112a is switched and used.

  Further, as shown in FIG. 13, the allocation information 112 and 113 may further allocate a button state for each button ID. As the state of the button, for example, the color of the button, the blinking of the button, etc. can be used as appropriate. The fact that the button state can be assigned is the same as the assignment information 112a of the second function.

  The user operation image information L2 is second image information representing the operator's hand or foot. The user operation image information L2 may be second image information including a human body part image representing a hand or a foot extracted from a live image of the first camera 13 or the second camera 14. The human body part image may represent from the wrist of the operator to the fingertip as the hand. Further, the human body part image may represent only the fingers used for the operation as the hand. Alternatively, the user operation image information L2 may be second image information including a simulated human body part image representing the hand or foot. As the user operation image information L2, as shown in FIGS. 14A and 14B, image information corresponding to the gesture may be used for each gesture of the operator. In the example shown in FIG. 14A, the user operation image information L2 includes both an image of a hand (human body part image) indicating a gesture of extending two fingers by the operator 200 and a cross-character indicating a user operation moving on the tablet terminal 12T. And a directional arrow. In the example illustrated in FIG. 14B, the user operation image information L2 includes an image of a hand indicating a gesture of extending the index finger by the operator 200, and an arc-shaped image indicating a user operation for designating (function execution) a button on the tablet terminal 12T. Including. Note that the gesture is not limited to finger movement or button designation, and any content can be set. As the number of fingers to be extended, any number between 1 and 5 can be used. Further, images other than the human body part image such as a bidirectional arrow or an arc-shaped image may be omitted from the user operation image information L2.

  Further, when the user operation image information L2 including the hand image as the human body part image is superimposed on the input I / F image information L1 of the tablet terminal 12T, as shown in FIG. 15A, it corresponds to the operation by the operator 200 by the hand. An operation screen g2 is generated. Similarly, when the user operation image information L2 including the hand image as the human body part image is superimposed on the input I / F image information L1 of the hardware console 12H, the operation by the operator 200 is performed as shown in FIG. 15B. A corresponding operation screen g2 is generated. Similarly, when the user operation image information L2 including a foot image as a human body part image is superimposed on the input I / F image information L1 of the foot switch 12F, an operation with the foot of the operator 200 is performed as shown in FIG. 15C. A corresponding operation screen g2 is generated.

  The operation auxiliary image information L3 is third image information including operation auxiliary information for each operation surface switch of the hardware console 12H, the tablet terminal 12T, and the foot switch 12F. Specifically, for example, the operation auxiliary image information L3 is the third image information including the operation auxiliary information (operation auxiliary information for each button ID on the operation surface) in the allocation information 112, 112a, 113, depending on the user operation. Used selectively. The operation auxiliary image information L3 is, for example, a balloon image describing a character string of the operation auxiliary information, and is used according to a user operation in which a finger stands by on a button. As the operation assistance information included in the operation assistance image information L3, the operation assistance information corresponding to the button ID of the button on which the finger is waiting is used among the operation assistance information in the allocation information 112, 112a, and 113. In the example illustrated in FIG. 16, in the allocation information 112 (not shown), the operation ID information including the character string “perspective map: save the previously fluoroscopically collected image as a moving image” is associated with the button ID “bt21”. Corresponds to the case.

  The input interface circuit 12 includes a trackball for setting a region of interest (ROI), a switch button, a mouse, a keyboard, a touch pad for performing an input operation by touching an operation surface, and a display screen and a touch pad. This is realized by an integrated touch panel display or the like. In the present embodiment, the input interface circuit 12 is a circuit operated by the operator's hand or foot, and is realized by the hardware console 12H, the tablet terminal 12T, and the foot switch 12F. The hardware console 12H includes hardware switches that are individually mounted by, for example, a plurality of plastic buttons, levers, dials, and the like and operated by an operator. The tablet terminal 12T includes a touch-operable touch panel display that displays software switches such as buttons. The touch panel display of the tablet terminal 12T is an example of an operation detection unit that detects an operation of the input interface circuit 12. However, in the present embodiment, the case where the first camera 13 and the second camera 14 are operation detection means will be mainly described as an example. The foot switch 12F includes a plurality of buttons (pedals) that can be stepped on. These input interface circuits 12 are connected to the control circuit 15, convert the input operation received from the operator into an electrical signal, and output it to the control circuit 15. In the present specification, the input interface circuit 12 is not limited to the one having physical operation parts such as a mouse and a keyboard.

  The control circuit 15 includes a processor and a memory (not shown), and the above-described various information input or set by the input interface circuit 12 is stored in the memory. The processor comprehensively controls each unit of the X-ray diagnostic apparatus 100 based on these input information and setting information, and performs safe and efficient X-ray imaging on the subject 150.

  In addition to this, the processor of the control circuit 15 calls and executes a program in the storage circuit 11, thereby realizing an input processing function 151, a screen generation function 152, a display control function 153, and a generation control function 154 corresponding to the program. . In FIG. 1, the input processing function 151, the screen generation function 152, the display control function 153, and the generation control function 154 have been described as being realized by a single control circuit 15, but a plurality of independent processors are combined. The control circuit may be configured so that each processor realizes each function by executing a program. Also, the assignment of the input processing function 151, the screen generation function 152, the display control function 153, and the generation control function 154 is convenient and can be changed as appropriate. For example, the screen generation function 152 may execute the execution contents (detection, etc.) of the input processing function 151.

  Here, the input processing function 151 is a function for executing input processing in accordance with the operation of the input interface circuit 12. As the input process, for example, there is a process of writing various information such as the image information L1 to L3 of each layer, the layout information 111, and the allocation information 112, 112a, 112a1, 112a2, and 112b in the storage circuit 11.

  In addition to this, the input processing function 151 may have a function of detecting an operation state based on outputs of the first camera 13 and the second camera 14. For example, (a) a situation in which the operator's hand or foot has moved, (b) a situation in which X-ray fluoroscopy or radiography is being performed, and (c) an operator does not move beyond a predetermined time. The situation, or (d) the situation where the operator is not photographed can be used as appropriate.

  Further, the input processing function 151 may have a function of detecting an operator's gesture based on outputs of the first camera 13 and the second camera 14. The input processing function 151 may have a function of detecting an operator's gesture based on the output of the tablet terminal 12T.

  Further, the input processing function 151 may have a function of detecting a switch in which the operator's hand or foot is approached based on the outputs of the first camera 13 and the second camera 14. The input processing function 151 may have a function of detecting a switch that the operator's hand approaches based on the output of the tablet terminal 12T.

  The screen generation function 152 generates operation screen data by superimposing user operation image information L2 on the input I / F image information L1 based on the outputs of the first camera 13 and the second camera 14 (or the tablet terminal 12T). It has a function to do. The screen generation function 152 may include, for example, the following function (f152a) or (f152b).

  (F152a): A function of generating operation screen data using the user operation image information L2 corresponding to the detected gesture.

  (F152b): A function of generating operation screen data by superimposing the operation auxiliary image information L3 corresponding to the detected switch.

  According to such a screen generation function 152, for example, as shown in FIG. 17, the operation screen g2 expressed by one image information L1 is expressed by two or three pieces of image information L1-L2, L1-L3. The operation screen g2 can be switched and displayed. Further, for example, the operation screen g2 expressed by the input I / F image information L1 of the page Pg1 with the allocation information 112 can be switched to the operation screen g expressed by the input I / F image information L1 of the other page Pg4. It becomes. Further, for example, as described in FIGS. 11 to 13, the operation screen g <b> 2 represented by the input I / F image information L <b> 1 in different assignment states can be switched and displayed based on the assignment information 112, 112 a, 113. Further, for example, as described in FIGS. 14A and 14B, it is possible to switch and display the operation screen g2 according to the gesture of the operator 200.

  The display control function 153 has a function of controlling the display circuit 7 so as to start or end the display of the operation screen g2 according to the operation status. The display control function 153 may include, for example, the following function (f153a) or (f153b).

  (F153a): A function of controlling the display circuit 7 to start displaying the operation screen g2 when the movement of the operator's hand or foot is detected as the operation status.

  (F153b): A function of controlling the display circuit 7 to end the display of the operation screen g2 when it is detected as an operation state that X-ray fluoroscopy or X-ray imaging is being performed. Thereby, for example, an operation that cannot be performed is not displayed, and an erroneous operation can be prevented.

  Note that when the display of the operation screen g2 is ended, the display control function 153 may control the display circuit 7 to switch the operation screen g2 to another screen g3 as shown in FIG. As another screen g3, for example, an information screen related to the subject 150 may be used. Alternatively, when the display of the operation screen g2 is ended, the other screen g3 may not be displayed in the area where the operation screen g2 was displayed.

  The generation control function 154 has a function of controlling the screen generation function 152 so as not to superimpose the user operation image information L2 or the operation auxiliary image information L3 according to the operation situation. For example, the generation control function 154 does not prepare one piece of image information L3 or two pieces of image information L2 and L3 depending on the operation situation. Accordingly, the screen generation function 152 can be controlled so that the image information L2 and L3 that are not prepared are not superimposed. As the operation situation, for example, a situation in which the operator does not move for a predetermined time or a situation in which the operator is not photographed can be used as appropriate. Thereby, for example, useless display such as displaying the operation auxiliary image information L3 when not operating can be prevented.

  The generation control function 154 may include at least one of the following functions (f154a) to (f154c), for example, as a function for preparing the user operation image information L2.

  (F154a): A human body part image representing a hand or a foot is extracted from a live image as an output of the cameras 13 and 14 that captures the input I / F circuit 12, and user operation image information L2 including the human body part image is prepared. function. Here, the human body part image may represent from the wrist of the operator to the fingertip as a hand. Further, the human body part image may represent only fingers used for the operation as hands.

  (F154b): When the human body part image represents only the finger used for the operation as a hand, the finger used for the operation is determined based on the shape of the hand represented in the live image, and the determined finger is represented. A function of extracting a human body part image and preparing user operation image information L2 including the human body part image.

  (F154c): When the storage circuit 11 stores user operation image information L2 including a simulated human body part image representing a hand or a foot, the user operation image information L2 is read from the storage circuit 11, and the user A function for preparing the operation image information L2.

  Next, the operation of the X-ray diagnostic apparatus configured as described above will be described with reference to FIGS. In the following description, after an operation by the operator is described, an operation of the X-ray diagnostic apparatus that supports the operation will be described.

(Operation by the operator)
Prior to X-ray imaging of the subject 150, the operator of the X-ray diagnostic apparatus 100 inputs subject information and sets X-ray irradiation conditions from the input interface circuit 12. Furthermore, the operator operates the input interface circuit 12 to operate the imaging system attached to the holding unit (C arm) 81 of the holding device 8 and the top plate 91 of the bed unit 9 on which the subject 150 is placed. Move / turn to position.

  Next, the operator inputs an X-ray fluoroscopic start command in the input interface circuit 12. As a result, the X-ray diagnostic apparatus 100 starts X-ray fluoroscopy with respect to the subject 150, and at this time, the imaging system is moved to a desired position under observation of fluoroscopic image data generated by the X-ray imaging unit 1 and the image generation circuit 6. Move towards.

  Next, the X-ray diagnostic apparatus 100 performs low-speed movement / rotation of the imaging system under observation of X-ray fluoroscopic image data. The operator sets the imaging system at a desired position of the subject 150 and starts commanding the X-ray imaging so as to stop the movement / rotation of the imaging system by operating the input interface circuit 12. A command signal for starting X-ray imaging is input.

  Upon receiving these command signals, the control circuit 15 performs X-ray imaging on the subject 150 based on preset X-ray imaging conditions.

  Thus, the operator operates the X-ray diagnostic apparatus 100 by operating the input interface circuit 12.

(Operation of X-ray Diagnostic Apparatus 100 for Supporting Operation: FIGS. 19 to 23)
Next, the X-ray diagnostic apparatus 100 operates as shown in steps ST1 to ST7 in FIG. 19 in order to support the above operation.

  In step ST1, the first camera 13 and the second camera 14 each photograph the input interface circuit 12. Here, the first camera 13 shoots the hardware console 12 </ b> H and the tablet terminal 12 </ b> T operated by the operator in the input interface circuit 12, and outputs moving image data to the control circuit 15. The second camera 14 takes an image of the foot switch 12 </ b> F that is operated by the operator's feet in the input interface circuit 12, and outputs moving image data to the control circuit 15.

  In step ST <b> 2, the input processing function 151 of the control circuit 15 detects the operation status based on the outputs of the first camera 13 and the second camera 14. For example, (a) a situation in which the operator's hand or foot has moved, (b) a situation in which X-ray fluoroscopy or radiography is being performed, and (c) an operator does not move beyond a predetermined time. There are situations, or (d) situations where the operator is not photographed. Further, the operation status may include (e) an operator's gesture, (f) a switch in which the operator's hand or foot is approached, and the like.

  In steps ST3 to ST7, the display control function 153 controls the display circuit 7 to start or end the display of the operation screen g2 according to the operation status. For example, when the display of the operation screen g2 is started, the screen generation function 152 is controlled so as to generate the operation screen g2. Further, when the display of the operation screen g2 is ended, the screen generation function 152 is controlled so as not to generate the operation screen g2. However, the present invention is not limited to this, and the operation screen g2 may be always generated and whether or not the operation screen g2 is displayed may be controlled. Hereinafter, a case where the screen generation function 152 is controlled will be described as an example.

  Specifically, in step ST3, the display control function 153 determines whether or not to display the operation screen g2 according to the operation status, and proceeds to step ST4 when displaying the operation screen g2. If the result of determination in step ST3 is no, the process returns to step ST1. Such step ST3 is executed, for example, as shown in steps ST3-1 to ST3-5 in FIG.

  That is, the display control function 153 is in a situation during fluoroscopy or radiography (step ST3-1; Yes), or a situation where the operator's finger and foot do not move (step ST3-2; No, ST3-3). ;), It is determined that the operation screen g2 is not displayed (step ST3-4). Further, the display control function 153 is in a situation where X-ray fluoroscopy or X-ray imaging is not being performed (step ST3-1; No), and the operator's finger or foot has moved (step ST3-2; Yes, ST3). -3; Yes), it is determined to display the operation screen g2 (step ST3-5). It progresses to step ST4 after step ST3-5.

  In step ST4, the generation control function 154 of the control circuit 15 prepares image information corresponding to the operation status among the three pieces of image information L1 to L3. Such step ST4 is executed, for example, as shown in steps ST4-1 to ST4-5 in FIG.

  That is, the generation control function 154 prepares the input I / F image information L1 by reading the input I / F image information L1 from the storage circuit 11 (step ST4-1).

  The generation control function 154 proceeds to step ST5 when the operator's hand or foot is not detected as the operation status (step ST4-2; No). When the operator's hand or foot is detected as the operation status (step ST4-2; Yes), the generation control function 154 reads the user operation image information L2 from the storage circuit 11, thereby the user operation image. Information L2 is prepared (step ST4-3). Note that the generation control function 154 may extract a human body part image representing a hand or a foot from a live image as an output of the cameras 13 and 14, and prepare user operation image information L2 including the human body part image. Alternatively, the generation control function 154 determines a finger to be used for the operation based on the shape of the hand represented in the live image, and extracts the human body part image representing the determined finger, whereby the human body part image User operation image information L2 including may be prepared. Further, when an operator's gesture is detected as the operation status, user operation image information L2 corresponding to the gesture is prepared.

  Furthermore, the generation control function 154 proceeds to step ST5 when the operator does not move beyond a predetermined time as the operation status (step ST4-4; No). When the operator moves within a predetermined time as the operation status (step ST4-4; Yes), the generation control function 154 reads the operation auxiliary image information L3 from the storage circuit 11, thereby the operation auxiliary image information. L3 is prepared (step ST4-5). Note that, when a button with the operator's hand or foot approaching is detected as the operation status, operation auxiliary image information L3 corresponding to the button is prepared. Here, the operation auxiliary image information L3 corresponding to the button is, for example, image information L3 including the operation auxiliary information corresponding to the button ID of the button. In any case, after step ST4-5, the process proceeds to step ST5.

  In step ST5, the screen generation function 152 of the control circuit 15 generates operation screen data by sequentially superimposing the image information L1 to L3 prepared in step ST4. That is, when only one image information L1 is prepared, the screen generation function 152 generates operation screen data from the input I / F image information L1. When only two pieces of image information L1 and L2 are prepared, the screen generation function 152 generates operation screen data by superimposing user operation image information L2 on the input I / F image information L1. When the three pieces of image information L1 to L3 are prepared, the screen generation function 152 superimposes the user operation image information L2 on the input I / F image information L1, and displays the operation auxiliary image information L3 on the user operation image information L2. Further, operation screen data is generated by superimposing.

  In step ST6, the large screen monitor 7a of the display circuit 7 displays the operation screen g2 visually recognized by the operator based on the operation screen data. The large screen monitor 7a is disposed away from the input interface circuit 12 operated by the operator's hand or foot.

  Therefore, the operator can operate the input interface circuit 12 while visually recognizing the operation screen g2 displayed on the large screen monitor 7a without visually recognizing the input interface circuit 12 at hand or foot.

  At this time, as shown in FIG. 22, it is assumed that illumination light or the like is reflected on the operation surface (glass surface) of the tablet terminal 12T in the input interface circuit 12. Even in this case, since the operation screen g2 displayed on the large screen monitor 7a uses the input I / F image information L1, the screen is not affected by the reflection and is easy to visually recognize.

  Further, as shown in FIG. 23, it is assumed that a drape 170 is hung on the hardware console 12H or the tablet terminal 12T in the input interface circuit 12. Even in this case, since the operation screen g2 displayed on the large screen monitor 7a uses the input I / F image information L1, the screen is not affected by the drape 170 and is easy to visually recognize.

  The above steps ST1 to ST6 are repeatedly executed until the operation of the X-ray diagnostic apparatus 100 is completed (step ST7).

  As described above, according to one embodiment, the first image information indicating the operation surface of the input interface means operated at the operator's hand or foot is stored. The screen generation means generates operation screen data by superimposing the second image information representing the hand or foot of the operator on the first image information based on the output of the operation detection means for detecting the operation of the input interface means. To do. The display means is arranged apart from the input interface means, and displays an operation screen visually recognized by the operator based on the operation screen data.

  Therefore, the operator can operate the input interface without visually recognizing the input interface at hand or foot. That is, conventionally, when performing a catheterization procedure or the like, the operator has viewed the medical image on the monitor, and then moved the line of sight to the foot switch or console to perform the switch operation. It was. On the other hand, according to one embodiment, since the operator can operate without visually recognizing the input interface at the hand or foot, the movement of the line of sight is less than in the conventional case, and the troublesomeness can be reduced.

  In addition to this, the operation screen g2 displayed on the large screen monitor 7a is used to input an image of a button such as the hardware console 12H or the foot switch 12F and information such as a button name or a picture for explaining the function of the button. / F image information L1 may be included. In this case, since information describing the function is included in the operation screen g2, the operator can easily understand the function. Even if the function is switched, the explanation of the function is switched and displayed, so that the operator can easily recognize the button setting. For example, even when the function assignment is changed in conjunction with the protocol, the information related to the changed function is displayed on the operation screen g2, so that the operator can determine the assigned function. Further, when setting of the button state (color, blinking state) is also possible, the operation screen g2 including the input I / F image information L1 according to the preference of the operator can be displayed. Similarly, even if the number input is assigned to the button and the function execution is assigned to the button, the assigned content is displayed on the operation screen g2, so that the operator can determine the assigned content. it can. Similarly, even if the button arrangement to which the first function is assigned and the button arrangement to which the second function is assigned are switched, the assigned content is displayed on the operation screen g2, so that the operator determines the assigned content. be able to. This also makes it possible to change the function assignment in units of button arrangement, such as page assignment for function assignment, which has heretofore been difficult.

  In addition, an operation screen g2 in which user operation image information L2 simulating an operator's hand or foot photographed by the first camera 13 and the second camera 14 is superimposed on the input I / F image information L1 described above is a large screen. It is displayed on the monitor 7a. Therefore, the operator can easily grasp the button arrangement and the position of the hand or foot, and can operate the button of the function that the user wants to execute from the medical image g1 or the subject 150 with a few eye movements. In addition, about the tablet terminal 12T, it replaces with the output of the 1st camera 13 and the 2nd camera 14, and prepares user operation image information L2 by tracing the movement of the finger on the operation surface of the said tablet terminal 12T. Also good. Further, as the user operation image information L2, image information including a human body part image representing a hand or a leg extracted from live images as outputs of the first camera 13 and the second camera 14 may be used. In this case, it becomes easier for the operator to grasp the arrangement of the buttons and the position of the hand or foot.

  Further, when the conventional tablet terminal 12T is viewed and operated, reflection is generated on the operation surface depending on the operator's standing position or installation position, and thus it is necessary to stare at the operation surface. Even when there is a reflection, the tablet terminal 12T cannot determine the button arrangement by groping because the operation surface is flat. On the other hand, according to one embodiment, the user operation image information L2 indicating the operator's finger is displayed on the large screen monitor 7a on the input I / F image information L1 indicating the operation surface. The positional relationship between the fingertip and the button arrangement can be determined without being affected by the reflection.

  Conventionally, when a protective sheet such as a drape 170 is put on the hardware console 12H or the tablet terminal 12T and a button or the like is operated from the protective sheet, the operator visually operates the drape 170 through the operation surface. There is a need. On the other hand, according to one embodiment, since the operation screen g2 including the input I / F image information L1 and the user operation screen information L2 is displayed on the large screen monitor 7a, the operator is affected by the drape 170. First, the positional relationship between the fingertip and the button arrangement can be determined.

  Further, according to an embodiment, third image information including operation assistance information on the operation surface may be further stored. In this case, operation screen data is generated by further superimposing the third image information on the second image information based on the output of the operation detection means. As a result, the limitation of the display range is relaxed compared to the case where the function description based on the button name or the pattern included in the input I / F image information L1 is limited to a narrow display range. Image information L3 can be displayed.

  Further, according to one embodiment, the third image information including the operation assistance information is stored for each switch on the operation surface, and the switch on which the operator's hand or foot approaches based on the output of the operation detection unit is stored. The operation screen data may be generated by superimposing the third image information corresponding to the detected switch. Thereby, for example, an operation including operation assistance information (e.g., character string, highlight display) of the button to be selected from the tip of the finger or foot detected from the output of the first camera 13 or the second camera 14. The auxiliary image information L3 can be displayed in a superimposed manner. Therefore, the operator's operation can be supported by displaying necessary operation assistance information in advance according to the operation status of the operator. Similarly, for the tablet terminal 12T, instead of the outputs of the first camera 13 and the second camera 14, the operation auxiliary image information L3 is prepared by tracing the movement of the finger on the operation surface of the tablet terminal 12T. May be.

  According to one embodiment, when the operation detection unit is a camera that photographs the input interface unit, the input interface unit may include a hardware switch operated by the operator. In this case, the operation screen g2 can also be displayed for the hardware console 12H and the foot switch 12F that do not have an operation surface for displaying the switch so that the touch operation is possible.

  According to one embodiment, the second image information corresponding to the gesture may be stored for each gesture of the operator. In this case, operation screen data is generated using the second image information corresponding to the detected gesture. Thus, by using a gesture corresponding to the item to be determined, the operation screen g2 based on the second image information corresponding to the item to be determined can be displayed.

  For example, the movement operation and the function confirmation operation are set to different gestures on the tablet terminal 12T. As the gesture, for example, it is determined that a two-finger operation represents a movement operation and a one-finger operation represents a function determination operation. In this case, it becomes possible to detect the movement operation and the function confirmation operation, and the operator's movement operation and function confirmation can be easily discriminated.

  According to one embodiment, the operation state may be detected based on the output of the operation detection unit, and the display unit may be controlled so as to start or end the display of the operation screen according to the operation state. In this case, it is possible to detect the timing at which display is required from the operation status including motion such as the movement of the operator's hands and feet, and to control whether the operation screen is displayed. For example, the display unit may be controlled to start displaying the operation screen when the movement of the operator's hand or foot is detected as the operation status. In addition, for example, when it is detected as an operation state that X-ray fluoroscopy or X-ray imaging is being performed, the display unit may be controlled to end the display of the operation screen.

  Further, according to one embodiment, the operation state may be detected based on the output of the operation detection unit, and the screen generation unit may be controlled so as not to superimpose the third image information according to the operation state. The operation situation may be a situation where the operator does not move for a predetermined time or a situation where the operator is not photographed. In these cases, the operation screen g2 can be switched and displayed so as not to include the operation auxiliary image information L3 when the operation auxiliary display is not required due to the operation status of the operator.
