Laser Positioning Aid
A low-power laser located in the scanner arm indicates the exact position of the x-ray beam. The laser beam is
aligned with the narrow x-ray beam in the table and serves as an aid in marking or defining anatomical land-
marks. The laser is turned ON and OFF by pressing the LASER button on the Scanner Arm Touch Pad.
When the laser is ON, the indicator next to the laser button is illuminated.
Although it is a low-power laser, the following precautions should be noted:
Do not stare into the beam.
Do not allow the laser to shine into your eyes. If the laser light does briefly shine into your eyes, it may startle
you, but will not cause immediate damage.
Do not allow shiny objects to reflect laser light into your eyes.
Computer/Controller
The Norland Bone Densitometer is controlled by a desktop PC. The computer is designed and configured to
operate the Norland Bone Densitometer system and should not be used for any other purpose. The computer
is certified as an X-Ray Controller at Norland's manufacturing facility, as required by the FDA.
Software
The Norland Bone Densitometer software conforms to a Windows style design for ease of use and familiarity.
Features of the Norland software include menu driven operation for system calibrations, scan data collection,
scan analysis and patient file management.

lished at the factory.
