9.5.2. Scatter radiation specification
Dose Contour Plot Test
This test method is according to clause 203.13.4 in IEC 60601-2-43:2010. This test is performed at
fluoroscopic mode in 110kV.The radiation field size is 100 cm2 at the entrance of the phantom.
The measurement is performed at 2 planes at typical height: 1m & 1.5m from the ground.
The scatter radiation is measured in 2 layouts as vertical and lateral configuration.
For the vertical configuration, the table is at height 1m. I.I. is above the tube.
For the lateral configuration, the table is at height 1m. The center of I.I. is at same altitude as the center
of phantom. The distance from the surface of I.I. to center of phantom is 40cm.
The layout is as below:
