Bone densitometer chishandiso chekuyedza chekurapa chinoyera bhonzo remunhu uye inowana akasiyana data ane hukama.Iwo mainstream bone densitometers pamusika kutanga kwezana ramakore rechi21 akakamurwa kuita mapoka maviri: maviri-simba X-ray absorptiometry uye ultrasonic absorptiometry.Dual-energy X-ray absorptiometry Iyo X-ray absorptiometry inowana marudzi maviri esimba, anoti pasi-simba uye high-energy photon peaks, kuburikidza neimwe mudziyo kuburikidza X-ray chubhu.Mushure mekunge photon peak inopinda mumuviri, iyo scanning system inotumira iyo yakagamuchirwa chiratidzo kune komputa kuti igadzirise data kuti iwane bhonzo mineral content.Icho chiridzwa chinogona kuyera mapfupa emapfupa mune chero chikamu chemuviri nehupamhi hwepamusoro uye hushoma kukuvadza kumuviri wemunhu.Mushonga wemwaranzi yekuona chikamu wakaenzana ne1/30 yechipfuva X-ray uye 1% yeCT.Hapana chinetso chokuora kwemwaranzi inobudisa mwaranzi, uye yakagadziridzwa zvishoma nezvishoma mumaguta makuru muChina, uye tarisiro yacho iri kuvimbisa.
Iyo mbiri-simba X-ray absorptiometry system ine X-ray chubhu, collimator, uye X-ray detector.X-ray photons inobudiswa ne-X-ray tube, iyo ine cathode uye anode, iyo yakavharirwa muhuputi hwehuputi.Inenge 99% yesimba re X-ray chubhu inopera sekupisa, uye isingasviki 1% yesimba inova X-rays.X-ray danda rinobatanidzwa kuita danda rakatetepa rakaita sefan risati rasvika panzvimbo iri kuyerwa.Iyo collimator inoshandiswa kudzora uye kumanikidza irradiation munda weiyo imaging danda kuti ive nechokwadi chekuti danda rinogona kunyatsovhara iyo inoshanda yekufungidzira nzvimbo ye detector.Iyo X-ray danda rinopfuura nepakati penzvimbo uye rinosarudzwa kuderedzwa nebhonzo uye zvinyoro zvinyoro munzvimbo iyoyo.Kana X-ray danda richipfuura nemurwere, rinorova X-ray detector, uye kusimba kwemwaranzi mushure mokupfuura nemuviri kunoshandurwa kuva zviratidzo zvemagetsi uye kunyorwa.
Iyo Whale3025/1613 yakatevedzana dynamic flat panel detector yakazvimiririra yakagadziridzwa neHaobo inotora amorphous silicon (a-Si) zvinhu tekinoroji, ine hunhu hwemhando yepamusoro yemufananidzo, hombe ine simba renji uye kuwanda kweterminal application.Iine maitiro akawanda ekugadzirisa purogiramu-inodzorwa nekugadzirisa magiya, ayo asingagoni kungosangana nezvinodiwa zvekushandiswa kwekunzwa kwepamusoro, asi zvakare kusangana nezvinodiwa zvemasimba makuru emamiriro ezvinhu, uye inogona kushandiswa zvakanyanya kune zvinodiwa zvekushandiswa kwekuonekwa kwechiremba.
