11.10.2 How To Test
1 Set measurement points with 500 mm intervals at the front, back, left, and right of the
equipment, making the rotation axis as the center.
(Measurementrange:(-1.5[m]to1.5[m])x(-1.5[m]to1.5[m]).(exceptthosemeasurement
points that are in contact with the equipment).
2 Adjust the dosimeter at the same height as the center line (focus height) of X-ray.
3 Place a cylindrical acrylic water tank (pictured above) at the rotation center as the imag-
ing subject.
4 Place the dosimeter at every measurement point, and measure the dose.
