Ultrasonic diagnostic equipment

Ultrasonic imaging diagnostic tekinoroji yanga ichikura kweanopfuura hafu yezana ramakore muChina.Nekuenderera mberi kwekuvandudzwa kwehunyanzvi hweruzivo rwemagetsi uye tekinoroji yekufungidzira kwekombuta, ultrasonic diagnostic equipment yakavewo shanduko yekuvandudza kwenguva dzakawanda, kubva paanalogi chiratidzo/dema uye chena ultrasound/harmonic musiyano/kuzivikanwa kwekugadzira, kuenda kudhijitari chiratidzo/ruvara ultrasound/elastic imaging/ artificial intelligence.Mabasa matsva uye mazinga ekushandisa ari kuramba achiwedzera, uye ultrasonic imaging diagnostic equipment inoramba ichivandudza uye nekuputsa, zvichiita kuti indasitiri yezvokurapa ive nechido chikuru chayo.

01. Basic classification yezvakajairwa ultrasonic imaging diagnostic equipment

Ultrasonic imaging diagnostic equipment imhando yekiriniki yekuongorora michina yakagadzirwa zvinoenderana nemusimboti we ultrasound.Kuenzaniswa nemidziyo yakakura yekurapa yakadai seCT uye MRI, mutengo wayo wekuongorora wakaderera, uye ine zvakanakira zvisiri-invasive uye chaiyo-nguva.Nokudaro, kushandiswa kwekliniki yakawanda uye yakawanda.Parizvino, kuongororwa kweultrasound kwakakamurwa kuita A-type ultrasound (one-dimensional ultrasound), B-mhando yeultrasound (two-dimensional ultrasound), matatu-dimensional ultrasound uye mana-dimensional ultrasound.

Inowanzo kunzi B-ultrasound, inoreva dema uye chena maviri-dimensional B-ultrasound, iyo yakaunganidzwa mufananidzo ndeya nhema uye chena-maviri-dimensional ndege, uye ruvara rweultrasound ndiyo yakaunganidzwa chiratidzo cheropa, mushure mekombuta yeruvara rwekodha pa. iwo maviri-dimensional mufananidzo mune chaiyo nguva superposition, ndiko kuti, kuumbwa kweruvara Doppler ultrasound ropa mufananidzo.

Three-dimensional ultrasonic diagnostic yakavakirwa paruvara Doppler ultrasonic diagnostic instrument, data acquisition device inogadziriswa, uye kuvakwazve kwemufananidzo kunoitwa kuburikidza nematatu-dimensional software, kuitira kuti igadzire mudziyo wekurapa unogona kuratidza matatu-dimensional imaging basa, kuitira kuti. nhengo dzevanhu dzinogona kuratidzwa zvakanyanya stereoscopic uye maronda anogona kuwanikwa zvakanyanya intuitively.Iwo mana-dimensional color ultrasound anobva pane matatu-dimensional color ultrasound pamwe neiyo nguva vector yechina dimension (inter-dimensional parameter).

 

02. Ultrasonic probe mhando uye mashandisirwo

Mukuita kweiyo ultrasonic image diagnostic, ultrasonic probe chikamu chakakosha che ultrasonic diagnostic equipment, uye iri mudziyo unotumira uye unogamuchira mafungu e ultrasonic mukuita kwekuonekwa kwe ultrasonic uye kuongororwa.Kuita kweiyo probe kunobata zvakananga maitiro eiyo ultrasonic uye ultrasonic yekuona kuita, saka iyo probe inonyanya kukosha mu ultrasonic mufananidzo kuongororwa.

Mamwe akajairwa probes mu ultrasonic probes anonyanya kusanganisira: single crystal convex array probe, phased array probe, linear array probe, vhoriyamu probe, cavity probe.

1, single crystal convex array probe

Iyo ultrasonic image chibereko chekubatanidzwa kwepedyo kweprobe uye system platform, saka pamushini mumwe chete, software uye hardware inoda kusangana nezvinodiwa zveimwe crystal probe.

Iyo imwechete crystal convex array probe inotora iyo imwechete crystal probe zvinhu, iyo probe pamusoro yakakomberedzwa, iyo yekubata kumeso idiki, yekufungidzira munda wakaita sefan, uye inoshandiswa zvakanyanya mudumbu, kubereka, mapapu uye zvimwe zvidimbu zvehama. nhengo dzakadzika.

Kuongororwa kenza yechiropa

Iyo probe surface yakati sandara, nzvimbo yekubata idiki, iyo yemunda yepedyo idiki, iyo yekure munda yakakura, uye iyo yekufungidzira ine shape-shape, iyo inokodzera moyo.

Mishonga yemwoyo inowanzokamurwa kuva mapoka matatu maererano nehuwandu hwekushandiswa: vanhu vakuru, vana, uye vachangobva kuberekwa: (1) vanhu vakuru vane nzvimbo yakadzika yemwoyo uye inononoka kurova;(2) Nzvimbo yemwoyo uchangobva kuberekwa haina kudzika uye kukurumidza kurova ndiko kunokurumidza;(3) Mamiriro ezvinhu emwoyo yevana ari pakati pevacheche nevakuru.

3, linear array probe

Iyo probe pamusoro yakati sandara, nzvimbo yekubata yakakura, nzvimbo yekufungidzira ine rectangular, kugadzirisa kwekufungidzira kwakakwira, kupinza kwakadzikira, uye kwakakodzera kuongororwa kwepamusoro kwetsinga dzeropa, nhengo diki, musculoskeletal zvichingodaro.

4, volume probe

Pahwaro hwemaviri-dimensional mufananidzo, vhoriyamu probe icharamba ichiunganidza nzvimbo yekugovera nzvimbo, kuburikidza nekombuta yekuvakazve algorithm, kuitira kuti uwane iyo yakazara spatial chimiro.Inokodzera: fetal face, musana nemakumbo.

5, mhango kuongorora

Iyo intracavitary probe ine hunhu hwepamusoro frequency uye yakakwirira mufananidzo resolution, uye haidi kuzadza dundira.Iyo probe iri pedyo nenzvimbo yakaongororwa, kuitira kuti nhengo yepelinha iri munharaunda yepedyo yemuti wezwi, uye chifananidzo chacho chakajeka.
