pDEXA
When you need to track your patients' bone density, the pDEXA is the most
convenient way to obtain accurate and timely information.
It is a dual energy x-ray bone densitometer that's small enough to fit
on a desk. Features include: design simplicity, laptop &
printer configurable, initial & follow up scans from the same region
of interest, and portable.
pDEXA is easy to use with step-by-step instructions clearly presented on
the computer screen. Automated analysis results in full color
printouts.
