保持DSA机参数设置固定不变，在床单位头足两个垂直探测平面分别设置探测

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 in the two vertical detection planes of the head and foot 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 in turn. The coordinate 0 points of the two vertical detection planes are located at the intersection of the left side of the head end of the bed unit with the ground level and the left side of the foot end with the ground level. The radiation detector is placed at the intersection of each XY axis value, so that the radiation The detector ray acquisition window faces the bed unit. 28 radiation parameters can be obtained corresponding to each vertical detection plane.

Set the vertical values of the detector on the Y-axis of 0 and the detector on the vertical axis of 90 and the detector on the fixed axis of 120, and set the detector on the vertical axis of 120. Corresponding to each vertical Y-axis value, adjust the horizontal X-axis value and set it to 0, 30, 60 and 90 in turn. The coordinate 0 points of the two vertical detection planes are located at the horizontal intersection between the left side of the head end and the ground and the left side of the foot end and the ground respectively. 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. Each vertical detection plane can obtain 28 radiation parameters.

Keep the parameter settings of DSA machine fixed, and set the vertical Y axis values of detector coordinates on the two vertical detection planes of the head and foot of the bed unit as 0, 30, 60, 90, 120, 150 and 180 respectively. Corresponding to each vertical Y axis value, adjust the horizontal X axis value and set it to 0, 30, 60 and 90 in turn. The coordinate zero points of the two vertical detection planes are respectively located at the horizontal intersection of the left side of the head end and the ground of the bed unit and the horizontal intersection of the left side of the foot end and the ground, and the radiation detector is placed at the intersection of each XY axis value so that the ray acquisition window of the radiation detector faces the bed unit. Each vertical detection plane can acquire 28 radiation parameters correspondingly.
