保持DSA机参数设置固定不变， 在床单位左右两个垂直探测平面分别设置探

Keep the parameter settings of the DSA machine fixed, and set the vertical Y-axis values ​​of the detector coordinates to 0, 30, 60, 90, 120, 150, and 180 on the left and right vertical detection planes of the bed unit respectively. Corresponding to each vertical Y-axis value, adjust the horizontal X-axis value and set it to 0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300 in turn. The coordinate 0 point is located at the intersection of the head end of the bed unit and the ground level, and the radiation detector is placed at the intersection of each XY axis value, so that the radiation detector ray acquisition window faces the bed unit. 77 radiation parameters can be obtained corresponding to each vertical detection plane.

Keep the parameter setting of DSA machine unchanged, set the detector coordinates on the left and right vertical detection planes of the bed unit, and the vertical Y-axis values are 0, 30, 60, 90, 120, 150 and 180 in turn. Corresponding to each vertical Y-axis value, adjust the horizontal X-axis value and set it to 0, 30, 60, 90, 120, 150, 180, 210, 240, 270 and 300 in turn. The coordinate 0 point is located at the horizontal intersection between the head end of the bed unit and the ground. Place the radiation detector at the intersection of each XY axis value so that the radiation acquisition window of the radiation detector is facing the bed unit. 77 radiation parameters can be obtained for each vertical detection plane.
