Based on the difference between the two beams the machine determines your bone density.
Dexa bone scan machine.
One is high energy and the other is low energy.
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.
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.
The machine measures the amount of x rays that pass through the bone from each beam.
You may be able to remain fully clothed depending on the area of your body being scanned.
Some people also call it a bone mass measurement test.
This is shortened to dexa.
Nof recommends a bone density test of the hip and spine by a central dxa machine to diagnose osteoporosis.
A dxa scanner is a machine that produces two x ray beams.
It will measure the x rays that pass through the bone from each beam.
Dxa is today s established standard for measuring bone mineral density bmd.
The dexa scanner uses two x ray beams.
One high energy and one low energy.
No special preparations are needed.
If your bone density is lower than normal for your age it indicates a risk for osteoporosis and.
Two x ray beams with different energy levels are aimed at the patient s bones.
Dexa solutions does not profit from the sale of the equipment directly however we will be the primary vendor involved in the deinstallation move and installation of the bone density machine other services are available upon request as well such as applications training.
Some radiation is absorbed by the bone and soft tissue and some travels through your body.
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.
Dxa stands for dual energy x ray absorptiometry.
This will vary depending on how thick your bone is.
Dual energy x ray absorptiometry dxa previously dexa is a means of measuring bone mineral density bmd using spectral imaging.
You can find out whether you have osteoporosis or if you should be concerned about your bones by getting a bone density test.
During a bone density scan a special type of x ray called dual energy x ray absorptiometry is passed through your body.
The instruments used for these tests are called peripheral devices and are often found in pharmacies.
A dexa scan is a high precision type of x ray that measures your bone mineral density and bone loss.
