Background technology
Bone density full name is bone mineral density, is an important indicator of bone strength, with a gram/cubic centimeter table
Show, is an absolute value.In Clinical practice bone density value due to the absolute value of different bone mineral density detectors difference, usually make
Judge whether bone density is normal with T values, T values are a relative values, and normal reference value is between -1 and+1.When T values less than-
It is abnormal when 2.5.Bone density is an important symbol of bone mass, reflects osteoporosis degree, predicts fracture risk
Important evidence.Due to the exploitation of measurement method being increasingly modified with advanced software, this method is made to can be used for different parts, measures essence
Degree significantly improves.
Dual energy X-ray absorptiometry (DEXA)：Two kinds of energy, i.e. are obtained by the excessively certain device of X-ray tube ball warp
Low energy and high-energy photon peak.After such photon peak penetrating body, scanning system send the signal received to computer into line number
According to processing, bone mineral content is obtained.The bone amount at any position of instrument measurable whole body, accuracy are high, harm to the human body compared with
Small, the radiological dose at one position of detection is equal to a rabat 1/30, and the 1% of QCT.The problem of there is no Radioactive Source Decays,
Gradually carry out in each big city in China at present, promise well.
The borne densitometers of domestic production at present are all single photon bone density machines, are to use Single photon as signal source, this
There are location difficulty, the disadvantages of measurement accuracy difference for borne densitometers, and two-photon or dual energy tune ray borne densitometers can overcome
These disadvantages, but domestic at present production, some large hospitals not yet start this kind of equipment of import foreign countries, and every is wanted ten tens of thousands of U.S.s
Member, so develop and produce as early as possible domestic dual energy borne densitometers not only and can fill up domestic blank, but also can be with
A large amount of foreign exchanges are saved, and the measurement that can greatly improve domestic bone density is horizontal, has very in clinical and practical application
Important value.
