Radiation Dose Per Scan Comparison

Radiation Dose Per Scan Comparison
Norland radiation dose to patients is the lowest in the industry. Constantly monitoring the
high energy count rate, Norland equipment automatically and dynamically varies x-ray flux
to one of eight levels to ensure an optimal count rate is used to carry out the scan of a
subject.

Norland Minimal Radiation Dosage
Norland utilizes exclusive dynamic filtration which
automatically adjusts the amount of x-ray based on
subject thickness. A benefit of dynamic
filtration is that it delivers the lowest level of
radiation exposure to the operator and subject in
the market. The dynamic filtering process
automatically adjusts radiation output based on
regional thickness. Limbs are less thick than
trunks and will require less radiation. Trunks are
typically thicker resulting in higher radiation
dosage. Other scanners employ fixed radiation
levels regardless of thickness producing detector
saturation (overestimation) or starvation (underestimation). The Norland
dynamic filters minimize radiation exposure while producing studies free of
detector saturation or starvation.
