Radiation Safety Features
Exposure Control
The exposure is controlled solely by the operator. The operator must click the
button on the com-
puter screen to initiate the exposure.
The exposure can be terminated by the operator at any time by clicking the
button in the Scan tab
window, or by pressing the
button directly below the Scanner Arm Touch Pad.
Note:
TO RESTART: To resume scanning after the EMERGENCY STOP button has been pressed,
rotate the switch clockwise to release it. Leave the computer power ON to retain the current study.
When scanning is resumed, the scanner arm will return to its origin position. ENSURE THAT THE
PATIENT IS NOT IN THE SCANNER ARM PATH!
Technique Factors
The technique factors (loading factors) are the operating parameters that determine the radiation exposure to
the patient. Tube voltage and tube current are fixed, highly regulated, and not subject to line conditions. They
are not controlled by the operator. Exposure time depends on the scan type and the size of the scan area.
Communication Watchdog
The Norland scanner includes a 'watchdog' circuit which monitors data collection communication during the
scan. If communication fails, the exposure is terminated.
Exposure Indicators
The green READY indicator
on the Scanner Arm Touch Pad illuminates to indicate that the x-ray
source is energized.
The yellow X-RAY indicator
is illuminated only when the beam shutter is open and the x-ray source is
energized. The X-RAY indicator extinguishes after the end of a scan when the beam shutter has closed and the
beam is not present. To prevent inadvertent x-ray exposure, the x-ray source will be automatically dis-
abled if the shutter malfunctions.
Radiation Shielding
System leakage and scatter radiation levels are very low and special shielding is not required. Room shielding
is not necessary and the operator does not have to be behind a barrier during the scan. At the typical distance of
3 feet from the beam, the radiation level is <0.1 mRem/hour. Norland recommends that operators position them-
selves at least three feet from the beam during the scan or as indicated by local state x-ray regulations.
Audible Indicator
An audible indicator sounds at the end of each scan. DO NOT DISCONNECT your computer speakers or turn
the sound level down too low. FDA regulations require this sound be heard.
Scanner Features
Some of the innovative features used in the Norland system are described in the following sections.
