Linearity of Radiation Output:
<.025 COV
Scatter Radiation
The direct and scattered beams can produce serious bodily injuries to patients and persons in the
surrounding area. Adequate precautions must always be taken to avoid or reduce exposure to
the useful beam, as well as scattered radiation.
Conditions of Operation
All data was acquired using two Technical Associates Mark V integrating ion chamber
meters. The data was acquired in concentric circles of radii listed in table below. A 16 cm
AAPM head phantom was placed within the beam to act as the scattering agent. The center
of the ion chamber was placed at the same height as the center of the beam, which was
verified to be the location of highest scatter.
Locations listed in the table are for 0°, 45°, 90°, 135°, 180°, 225°, 270° and 315°. Looking out
from the scanner, 0° was located directly in front.
