Term
Factors that affect the precision of patient BMD measurement
Give this one a try later!
-Scattered dose at side of the phantom by operator chair
-Entrance dose to phantom
-Monitor and assists with shewhart plotting results
-K-edge Filtering: Filters high energy photons from low energy photons (40-
80kV)
, -Voltage switching: switches between low and high energies (50-85kV)
-tech precision
-age and bone density of precision study population
-machine variability day to day
-different tech doing serial exams
-different DXA machine
It is uniform within a wide energy spectrum and with a wide range of atomic
numbers (basically will always occur)
