  The position information of the index unit 41 captured by the image sensor 47 and the operation information input by the input unit 51 received via the wireless communication units 45 and 57 are subjected to image processing by the image processing unit 21. Based on the operation signal output from the remote controller 43, the image processing unit 21 performs image processing for operating the screen, such as drawing a diagram on a fluoroscopic image or a captured image displayed on the first monitor 29. First, the image processing unit 21 displays the pointer P on the screen of the first monitor 29, and when the fluoroscopic image or the captured image is displayed, displays the pointer P on the fluoroscopic image or the captured image. Then, the pointer P displayed on the screen of the first monitor 29 is moved based on the relative position calculated by calculating the position information of the index unit 41 for each time.

  The operation of the remote controller 43 will be described. The surgeon OP directs the light receiving surface of the image sensor 47 of the remote controller 43 to the screen of the first monitor 29 including the indicator unit 41. When the index unit 41 falls within the imaging range of the image sensor 47, the index unit position calculation unit 49 recognizes the index unit 41 from the image captured by the image sensor 47 and calculates the relative position of the recognized index unit 41. To do. The position information of the index unit 41 calculated by the index unit position calculation unit 49 is transmitted as an operation signal to the image processing unit 21 via the wireless communication units 45 and 57. Based on the operation signal, the image processing unit 21 performs a process of moving the pointer P displayed on the screen of the first monitor 29. Thereby, the pointer P can be moved on the screen of the fluoroscopic image or the photographed image displayed on the first monitor 29 according to the movement of the remote controller 43 itself moved by the operator OP.

  At this time, if the position of the pointer P on the screen displayed on the first monitor 29 and the direction in which the operator OP points the light receiving surface of the image sensor 47 of the remote controller 43 toward the first monitor 29 are different, When the calibration button 51c is pressed in a state where the light receiving surface of the element 47 is directed to the center of the screen of the first monitor 29, the pointer P is displayed again at the center of the screen of the first monitor 29 by the image processing of the image processing unit 21. The

  For example, the pointer P displayed on the screen of the first monitor 29 moves to the right when the remote controller 43 itself is moved to the right, and moves to the upper left when the remote controller 43 itself is moved to the upper left. It is processed.

  When drawing a diagram on the screen of the first monitor 29, the diagram is drawn on the screen according to the position of the pointer P by moving the remote controller 43 itself while the diagram drawing button 51a is pressed. The In addition, the first point is specified by pressing the diagram drawing button 51a, and dragging while keeping the pressed state, and the diagram is drawn by specifying the second point by releasing the state where the diagram drawing button 51a is pressed. You may make it do. Since a diagram can be drawn, an arbitrary shape such as a figure or a character can be expressed. The diagram deletion button 51b moves the pointer P and directly deletes the diagram drawn by the diagram drawing button 51a, deletes the diagram by designating a range, or draws all on the screen. The image is processed so as to erase the line diagram.

  Please refer to FIG. For example, the operator OP inserts the catheter 62 into the blood vessel 61 of the subject M while observing the fluoroscopic image or the photographed image displayed on the first monitor 29 and reaches the treatment site 63. Assume that the screen S1 is being displayed. When the blood vessel 61 branches on this screen S1, the operator OP draws a diagram 64 on the screen S1 displayed on the first monitor 29 by using the remote controller 43 in the direction in which the catheter 62 is moved. Other staff members confirm the diagram 64 drawn on the screen S1 of the first monitor 29, and operate the top plate driving mechanism 9 and the C-type arm driving mechanism 13 to display the screen S2. At this time, when the screens S1 and S2 displayed on the first monitor 29 are fluoroscopic images, the image processing unit 21 displays a diagram 64 drawn on the screen S1 so as to follow the movement of the screen on the screen S2. Perform image processing to move to the corresponding position. Thereby, even if the screen on which the fluoroscopic image to be observed is displayed is moved, it is possible not to lose sight of the position drawn by the diagram 64. When the operator OP finds the treatment site 63 from the screen S2 of the first monitor 29, the operator OP draws a diagram 65 showing the position of the treatment site 63 displayed on the screen S2 using the remote controller 43. Other staff members who operate the operation panel 27 perform operations such as driving the C-arm drive mechanism 13 so as to move the treatment site 63 to the vicinity of the center of the screen, and scaling the screen.

  As described above, according to the X-ray fluoroscopic apparatus 1 of the first embodiment, the screen displayed on the first monitor 29 is operated by the remote controller 43, so that an image is output based on the operation signal output from the remote controller 43. When the processing unit 21 performs image processing, for example, a line drawing is drawn on a fluoroscopic image or a captured image displayed on the first monitor 29. Accordingly, the operator OP during the operation can perform operations on the screen such as drawing a diagram on the fluoroscopic image or the photographed image displayed on the first monitor 29 arranged at a distant position. In other words, the operator OP during the treatment can send an instruction to the surrounding staff by drawing a diagram on the fluoroscopic image or the photographed image on the first monitor 29 without going through the surrounding staff. Therefore, the confirmation work can be performed efficiently and a quick treatment can be performed.

  In addition, the remote controller 43 takes an image of the index unit 41 arranged on the first monitor 29 with the image sensor 47, and uses the relative position of the index unit 41 reflected in the image taken with the image sensor 47 as an index unit position calculation unit. By calculating at 49, the position information of the index unit 41 such as the movement distance and direction, that is, the position information of the remote controller itself is obtained. A preset operation is input through the input unit 51. By performing image processing in the image processing unit 21 based on the position information of the index unit 41 and the operation signal of the operation information from the remote controller 43, the operator OP is provided with the first monitor 29 arranged at a distant position. It is possible to arbitrarily operate the screen such as drawing a diagram on the fluoroscopic image or captured image displayed on the screen. Further, since the operator OP can operate the remote controller 43 by pointing the remote controller 43 toward the first monitor 29 and pointing the screen, the operation is easy.

  The X-ray fluoroscopic apparatus 1 includes a wireless communication unit 45 that performs wireless communication with the remote controller 43. That is, since the operation signal from the remote controller 43 can be wirelessly communicated to the image processing unit 21 via the wireless communication units 45 and 57, the operator OP can carry the remote controller 43 and be wired. Since there is no wiring by communication, the wiring does not get in the way and the operation can be facilitated.
