The expertise and the discipline of 2-dimensional measurement of the bone frame was established by 2 men of intellect and apparition: Dr. Richard Cameron and Dr. Richard Mazzes. The intellect of their planning nurtured the use of the notion of dual vigor x-ray distribution approaches to better distinguish between soft tissues from bone and thus improve the direct bone edge measurement.
A bone density examination, DEXA, gauges the mineral content of the bones in certain parts of the skeleton. It’s a way to calculate bone loss as you age. Healthcare suppliers occasionally call these examinations bone densitometry examinations, or DXA.
What is a DEXA examination?
A DEXA image is a kind of medical imaging examination. It uses very low planes of x-rays to calculate how thick your bones are. DEXA stances for “dual-energy X-ray absorptiometry.” Medical specialists consider DEXA examinations to be the most valuable, easy, and low-priced examination for facilitating the identification of osteoporosis.

2. As the limb of the DEXA machine made by the Bone Densitometer Manufacturers passes over the form, IT uses two diverse x-ray rays. The rays use very little radioactivity to keep the examination safe and help to differentiate bone from other nerves.
3. The scanner interprets the bone thickness measurement information into images and charts. Bone is most effortlessly understood in white, while the fat and muscle flesh look like glooms in the backdrop on the scientist’s computer screen.
4. These consequences are then studied and understood by a radiologist or other doctor trained in DEXA elucidation
5. Your healthcare supplier is sent a facsimile of the printed report to deliberate with you and consider what therapy is most suitable.
