Ultrasound midziyo inowanzoshandiswa mumapurazi enguruve, kunyanya kupfuya mapurazi, ayo anogona kushandiswa kuyera mimba, backfat, mhasuru yeziso, uye mimwe midziyo yekudzinga shiri nemhuka inoshandiswawo mu ultrasound.Iwe unogona kazhinji kushandisa michina ye ultrasound, asi iwe unogona kunge usingazivi imwe yeruzivo rwakakodzera, chinyorwa ichi ongororo yakapusa yeiyo ultrasound tekinoroji inoshandiswa mumapurazi enguruve.
Ultrasound
Ultrasound is high-frequency sound wave, huwandu hwenzeve yemunhu kunzwa ruzha wave 20Hz kusvika 20KHz, inodarika 20KHz (vibration 20 thousand times a second) sound wave iri mhiri kwekunzwa kwevanhu, saka inonzi ultrasound.
Iyo ruzha wave inoshandiswa neyakajairwa ultrasound michina yakakwira zvakanyanya kupfuura 20KHz, senge frequency yeyakajairwa yemagetsi convex array ultrasound nhumbu scanner ndeye 3.5-5MHz.
Chikonzero nei Ultrasound ichashandiswa kuona michina inonyanya kurongeka kwayo, kuratidza kwakasimba, uye kumwe kugona kwekupinda.Izvo zvakakosha zvemidziyo ye ultrasound ndeye transducer, inoshandura masaini emagetsi kuita mafungu e ultrasound kuti abudiswe, uye masaisai e ultrasound anotaridzwa kumashure anogamuchirwa ne transducer, ayo anoshandurwa kuita masaini emagetsi, uye masaini emagetsi anogadziridzwa zvakare kugadzira mifananidzo kana. inzwi.
A Ultrasound
Midziyo yeA-Ultrasound inowanzoshandiswa mumapurazi enguruve, kunyanya kumapurazi ekuberekesa, ayo anogona kushandiswa kuyera nhumbu, musana, tsandanyama yeziso, uye mimwe michina yekudzinga shiri nemhuka zvakare inoshandiswa muultrasound.Iwe unogona kazhinji kushandisa michina ye ultrasound, asi iwe unogona kunge usingazivi imwe yeruzivo rwakakodzera, chinyorwa ichi ongororo yakapusa yeiyo ultrasound tekinoroji inoshandiswa mumapurazi enguruve.

A Ultrasound
Sezvo mota inotenderera frequency ine muganho wepamusoro, iyo B-ultrasound ye mechanical probe ichava nemuganhu mukujeka.Kuti uwane kugadzirisa kwepamusoro, maprobe emagetsi akagadzirwa.Panzvimbo pekushandisa transducer inofambiswa nemuchina kubheuka, probe yemagetsi inoisa nhamba ye "A-ultrasound" (mafurashi) muchimiro checonvex, chimwe nechimwe chinodaidzwa kuti array element.Iyo yazvino inodzorwa neiyo chip inobvisa imwe neimwe array, nekudaro ichiwana inokurumidza chiratidzo kutumira uye kugamuchira frequency kupfuura mechanical probe.
Asi dzimwe nguva iwe uchaona kuti mamwe emagetsi convex array probes ane yakaipisisa yekufungidzira mhando pane yakanaka mechanic probes, iyo inosanganisira nhamba yezvirongwa, ndiko kuti, mangani arrays anoshandiswa pamwechete, gumi nematanhatu?32 vavo?64 vavo?128?Kuwanda kwezvinhu, mufananidzo wacho unowedzera kujeka.Ehe, iyo pfungwa yenhamba yechiteshi inobatanidzwawo.
Kupfuurirazve, iwe uchaona kuti ingave mechanic probe kana yemagetsi convex array probe, mufananidzo ichikamu.Mufananidzo wepedyo idiki, uye mufananidzo uri kure uchatambanudzwa.Mushure mekukanganisika kwekutumira uye kugamuchira masaini pakati pezvinhu zvakarongeka zvakundwa zvine hungwaru, hurongwa hwezvinhu zvinogona kuiswa mumutsara wakatwasuka, uye yemagetsi mutsara array probe inoumbwa.Mufananidzo wemagetsi array probe idiki diki, semufananidzo.Naizvozvo, kana uchishandisa linear array probes kuyera backfat, iyo matatu-layer lamellar chimiro chebackfat inogona kuratidzwa zvakakwana.
Nekuita kuti mutsara wemutsetse wekuferefeta uti kurei zvishoma, unowana mhasuru yeziso probe.Inogona kuvhenekera tsandanyama yeziso rose, uye hongu, nekuda kwemutengo wakakwira wemidziyo, inowanzoshandiswa chete mukubereka.
Pane C-ultrasounds uye D-ultrasounds?
Hapana C-ultrasounds, asi pane D-ultrasounds.D ultrasound ndiyodoppler ultrasound, ndiko kushandiswa kwedoppler musimboti ultrasound.Tinoziva kuti inzwi rine adoppler effect, inova kana chitima chikapfuura pamberi pako, ruzha runoenda nekukurumidza uye zvishoma nezvishoma.Kushandisadoppler's musimboti, anogona kukuzivisa iwe kana chimwe chinhu chiri kufamba chakananga kwauri kana kure newe.Semuenzaniso, pakushandisa ultrasound kuyera kubuda kweropa, mavara maviri anogona kushandiswa kuratidza kubuda kweropa, uye kudzika kwemavara kunoshandiswa kuratidza kubuda kweropa.Izvi zvinonzi color ultrasound.
Ruvara rwe ultrasound uye ruvara rwenhema
Kune vanhu vazhinji vanotengesa B-ultrasound vachashambadza kuti zvigadzirwa zvavo zvine ruvara rwe ultrasound.Zviripachena kwete ruvara rweultrasound (D-ultrasound) ratakataura nezvarwo mundima yapfuura.Izvi zvinogona kungonzi fake color.Nheyo yacho yakafanana neTV yakasviba uye chena ine jira refirimu remavara.Imwe neimwe poindi paB-ultrasound inomiririra kusimba kwechiratidzo chinoratidzwa pachinhambwe ichocho, chinoratidzwa negrey scale, saka ndeupi ruvara rwakanyanya kufanana.
A-Ultrasoundinogona kufananidzwa ne-one-dimensional code (bar code);B-ultrasound inogona kufananidzwa nekodhi-dimensional code, ine ruvara rwenhema B-ultrasound yakanyorwa maviri-dimensional code;D-Ultrasoundinogona kufananidzwa netatu-dimensional kodhi.
