  When performing fluoroscopy at the time of surgery using the X-ray imaging apparatus having the above-described configuration, as shown in FIG. 3, the doctor 42 performs the surgery at a position closest to the knee of the patient 41 to be operated. The operator 44 operates the operation panel 51 on the side of the apparatus main body 11 in response to an instruction from the doctor 42. At this time, the operator 44 operates the input unit 16 or the operation panel 51 in advance to call an anatomical program corresponding to the registered imaging region. The anatomical program is read from the anatomical program storage unit 72 by the control unit 60. Then, fluoroscopy is started.

  FIG. 6 is a schematic diagram showing a fluoroscopic image displayed on the display unit 17.

  When the X-ray imaging apparatus is arranged in the state shown in FIG. 3, the X-ray fluoroscopic image is inclined as shown in FIG. 6A, and the area other than the affected part is also displayed. In this state, it is difficult for the doctor 42 to confirm the image of the affected area, so that the operator 44 operates the operation panel 51 to rotate the image and adjust the X-ray irradiation field. At this time, when the operation panel 51 is operated, the entire collimator 23 is rotated by driving the collimator rotating motor 82, and the camera 33 is rotated by driving the camera rotating motor 83. Further, the collimator leaf 24 in the collimator 23 moves.

  In this state, when the operator 44 holds down the memory key 52 on the operation panel 51 for a long time, image display information including the rotation angle position of the collimator 23, the rotation angle position of the camera 33, and the opening amount of the collimator 23 is obtained. The memory key is stored in the memory key storage unit 71 in association with the memory key 52. In parallel with this, the image display information stored in the memory key storage unit 71 and the anatomical program stored in the anatomical program storage unit 72 are associated and stored in the related information storage unit 73.

  When performing surgery, the affected part is often seen through from two directions orthogonal to each other. In this case, the C-arm 13 is rotated 90 degrees by the operation of the operator 44. When the operator 44 performs a fluoroscopy in this state and presses and holds the memory key 53 on the operation panel 51, the rotation angle position of the collimator 23, the rotation angle position of the camera 33, and the opening of the collimator 23 at this time are displayed. The image display information including the quantity is stored in the memory key storage unit 71 in association with the memory key 53. Also at this time, the image display information stored in the memory key storage unit 71 and the anatomical program stored in the anatomical program storage unit 72 are associated and stored in the related information storage unit 73.

  At this time, it corresponds to the image display information including the rotation angle position of the collimator 23, the rotation angle position of the camera 33, and the opening amount of the collimator 23 stored for the memory keys 52 and 53 on the operation panel 51. Image display information is stored in memory keys 55 and 56 on the other operation panel 54. In general, when performing fluoroscopy during surgery, the X-ray imaging apparatus is often fluoroscopically viewed from a symmetrical position with respect to the patient 41 as shown in FIGS. 3 and 4. Therefore, the image display information corresponding to the image display information registered for the memory keys 52 and 53 on the operation panel 51 is automatically stored in the memory key storage unit 71.

  Here, the image display information stored at this time is the rotation angle position stored for the memory keys 52 and 53 on the operation panel 51 with respect to the rotation angle position of the collimator 23 and the rotation angle position of the camera 33. The collimator 23 is rotated in the opposite direction by the same angle, and the opening amount of the collimator 23 is the same as that stored for the memory keys 52 and 53 on the operation panel 51. Also at this time, the image display information stored in the memory key storage unit 71 and the anatomical program stored in the anatomical program storage unit 72 are associated and stored in the related information storage unit 73.

  In this state, when the operation is completed and the next knee operation is performed, when the operator 44 calls the anatomical program previously registered in association with the image display information, the information is stored in the related information storage unit 73. Based on the information, image display information including the rotation angle position of the collimator 23, the rotation angle position of the camera 33, and the opening amount of the collimator 23 stored for the memory keys 52 and 53 on the operation panel 51, and the operation The image display information including the rotation angle position of the collimator 23, the rotation angle position of the camera 33, and the opening amount of the collimator 23 stored for the memory keys 55 and 56 on the panel 54 is called. Then, the image display information registration unit 74 registers the image display information corresponding to each memory key 52, 53, 55, 56 in each memory key 52, 53, 55, 56.

  When the next operation is performed, by pressing each memory key 52, 53, 55, 56, the rotation angle position of the collimator 23, the rotation angle position of the camera 33, and the opening amount of the collimator 23 are set in advance. It is automatically adjusted so that it becomes the value that was set. For this reason, it is not necessary for the operator 44 to register the memory keys 52, 53, 55, and 56 every time, so that the photographing efficiency can be improved.
