Why choose Vision Exercise Physiology?
The MediLink MedixDR DEXA system produces the highest image resolution
out of the four major brands. It has 256 detector elements, compared with
Lunar with 64 and Hologic with 128. Medilink elements are also stacked,
which allows multiple focal depths, meaning better sensitivity.
Higher resolution images increase the accuracy of compartmental
differentiation and visual representation of adipose tissue. This is evident
by the images produced by the Medilink Medix DR.
DEXA Comparisons
Some DEXA brands are prone to beam hardening, where the machine is
unable to detect the smaller lower density fatty deposits within the higher
density muscle/lean tissue*
Lower resolution scanners produce a simplified composition image, where
entire regions are ‘painted’ with colours and fail to show any detail or fat
deposits.
