Dexa Bone Scan Machine

The dexa scanner uses two x ray beams.

Dexa bone scan machine. You may be able to remain fully clothed depending on the area of your body being scanned. A bone density scan is a quick and painless procedure that involves lying on your back on an x ray table so an area of your body can be scanned. Dxa is today s established standard for measuring bone mineral density bmd. No special preparations are needed.

Dxa stands for dual energy x ray absorptiometry. Dual energy x ray absorptiometry dxa previously dexa is a means of measuring bone mineral density bmd using spectral imaging. The instruments used for these tests are called peripheral devices and are often found in pharmacies. Based on the difference between the two beams the machine determines your bone density.

Bone density scanning also called dual energy x ray absorptiometry dxa or bone densitometry is an enhanced form of x ray technology that is used to measure bone loss. This is shortened to dexa. A small portable machine can measure bone density in the bones at the far ends of your skeleton such as those in your finger wrist or heel. This will vary depending on how thick your bone is.

Some people also call it a bone mass measurement test. Tests of peripheral bone density are less expensive than are tests done on central devices. Special detectors in the dexa machine measure how much radiation passes through your bones and this information is sent to a computer. One is high energy and the other is low energy.

A dxa scanner is a machine that produces two x ray beams. The expert field engineers at dexa solutions are involved. What is a bone density scan dexa dxa. Some radiation is absorbed by the bone and soft tissue and some travels through your body.

A dexa scan is a high precision type of x ray that measures your bone mineral density and bone loss. The machine measures the amount of x rays that pass through the bone from each beam. During a bone density scan a special type of x ray called dual energy x ray absorptiometry is passed through your body. Nof recommends a bone density test of the hip and spine by a central dxa machine to diagnose osteoporosis.

One high energy and one low energy. Two x ray beams with different energy levels are aimed at the patient s bones. It will measure the x rays that pass through the bone from each beam.
