Sonography. Chii uye chii chinoita kutsvakurudza nzira

Kana chiremba zvinoreva murwere kuti Ultrasound, mibvunzo vakawandisa hakuiti kazhinji simuka. Asi kana kugadzwa vakashandisa asinganzwisisiki shoko "Ultrasound", mibvunzo achidira yakaita pizi. Saka, zvinokosha kunzwisisa, sonography - chii? Uye mune zvimwe zviitiko, murwere anopiwa yakafanana basa.

Association

Wokutanga murwere Songaniro kwakabatana kurara, asi Ultrasound hazvinei nechokuita nazvo. Ultrassom uye sonography - mazita akasiyana nokuda chete nzira. Nokuti zvakafanana tsvakurudzo pacho rinoshandiswa zita sonography. Kubva musi uyu, tinogona kugumisa nyore: Ultrasound, Ultrasound, Ultrasound - chii? Ultrasound ichi unobereka tinyatsonzwisisa morphological uye dzichipfekeka parameters zvomukati uye nyama dzevanhu.

On chii nzira

Ultrassom nzira inobva zvaiva ultrasonic nemafungu nomuviri ndakarovha. Chero chipenyu miviri ine nyama dzakasiyana arambe achirema uye nemishonga. With Ultrasound ichi zvinoratidzwa, refracted, akapararira kana zvakawanda. Somugumisiro, nokupiwa mudziyo mufananidzo kunoitika. Ndizvo chaizvo rakaita zvokurekodhwa Ultrasound ungira anonongedzera akaratidza kubva zvinhu.

Medical midziyo nokuti Ultrasound (sonography) rinoshandisa kakawanda 1.5 kusvika 29 MHz. The kunonyanyisa nenamo kuti inogona panoonekwa vanhu nzeve, 20 kHz. The zvichiguma mufananidzo - kwete chete gandiwa ari womukati nhengo kana pfupa mugove sezvo x-mwaranzi, uye Mapping yomunyika hurongwa.

tsananguro pfupi Ultrasound Machine

Kuitisa kuongorora uchishandisa mishonga Ultrasound muchina. Sonography - chii? Kana namano ose akafanana? Ndezvipi zvinhu ivo ine? Chinhu chakanakisisa ari mudziyo Ultrasound midziyo anzwisise wefizikisi. Vanonzwisisa ndeipi piezoelectric chaizvoizvo, aiziva urefu, vibrations uye frequencies. Munhuwo murwere zvakakwana kuziva kuti mudziyo chinosanganisira zvinotevera zvinhu:

• jenareta pamusoro ultrasonic mafungu, i.e. kupomba jenareta emitting uye panguva imwe chete vachagamuchira kunooneka anonongedzera;
• ultrasonic Switch-transdyusora, izvo dzimba vazhinji pezokristallicheskih transducers ari Switch kune uchirapwa gogorosi unokubvumira nezvekufirwa achida kudzika.

Types transdyusorov (Switch)

The kwokutanga nokupesana rinoitwa pasi zvemaziso uye zvemagetsi. Kushanda pakuvheneka zvokuimba Switch iri kuteererwa kwebasa wakaisvonaka chinhu (rotation kana Kuzunungusa). The chikuru drawback - yakaderera chisarudzo mifananidzo, vibration uye basa ruzha. Modern Ultrasound sonography kusiya yechinyakare womuenzaniso, vachisarudza havo kushandisa electronic shanduro.

Electronic sensors vari midziyo yakawanda yemazuva ano. Scan mifananidzo zvinoberekwa zvemagetsi nzira. The mufananidzo zvikuru zvakajeka uye kwakakwana. Ruzha uye vibration kana kunoshandisa michina vasipo.

Ultrasonic kushanda pakuvheneka yakakamurwa kuva Linear, convex uye zvekutepfenyura mhando. Nokudaro, vakashandisa 3 siyana sensors:

1. Linear. It anoshandisa kakawanda 5-15 MHz. Outputs mufananidzo mapazi kuongororwa dzakakwirira chisarudzo mifananidzo, nhengo mutengo unoenderana upamhi Switch, asi kudzama kushanda pakuvheneka kwete kupfuura 11 cm. Zvakaoma kupa yakafarikana yunifomu kuonana Switch kuwana yepamusoro mufananidzo. Kushandiswa atarise thyroid, mazamu, svikiro kadikidiki mapfundo tsandanyama tishu.
2. Convex. 1,9-7,5 MHz maitikiro. Kushanda pakuvheneka pemvura urefu duku pane mutsetse Switch. Kunovimbisa zvakasimba yunifomu kuonana kusvika ganda. Anopa nepaburi mufananidzo, zvimwe yakavhiringidzwa kukura, asi rokuongorora udzamu kune masendimita 25. Rinoshandiswa kuti pakuongorora abdominal mhango uye retroperitoneal, urogenital hurongwa, majoini guru (hudyu, somuenzaniso).
3. Zvekutepfenyura. It anoshandisa kakawanda 1.5-5 MHz. Image hombe chaiyo. Rinopa kukwanisa tarisei panguva kudzika kukuru. Most anowanzoshandisirwa echocardiography.

Mhando dzakasiyana-siyana sensors inoshandiswa kuongorora abdominal zvomukati, mwoyo, thyroid, zamu, nomuzongoza uye mapfundo. Uyezve, pane microsensors kuti endoscopy uye biopsy tsono.

Kuongorora vakadzi vane pamuviri

The yakanakisisa kuita kuti uzere kuongorora vakadzi vane pamuviri anonzi kuva sonography kombiyuta. Zvombo zvakadaro anobvumira kunyatsofungisisa kufunga mamiriro nhengo ari mudumbu, kubva chetyrehsantimetrovogo saizi. The Ongororo yakachengeteka zvachose. Zvinobatsira vaine vhiki rechina pamuviri kuteerera kurova kwehana, kuziva uye kubvisa ngozi yokubva pamuviri yakakura, gestational kujekesa, ziva zvokukura sokunonoka nezvimwe zvarakasiya.

Patency of fallopian sepombi

Kudikanwa kuongorora patency ari fallopian sepombi kunoitika vakadzi, vasingagoni mimba kwenguva refu kumwedzi. Sonography of fallopian sepombi - nzira kuongorora zvikonzero izvo zai havagoni kusangana urume.

Chokutanga, chiremba anoongorora mamiriro ari uterine mhango, iva nechokwadi chokuti mukadzi haasi nepamuviri uye asina adhesions, polyps uye nzvimbo. Uyezve, muromo wechibereko Canal chinotarisirwa sesaline uye dzinoongororwa kushandisa sonography fallopian sepombi. Kana pombi vari passable, nemvura iri vakapedzwa kubva mativi ose nhengo mudumbu. Kana mvura haisi asunungurwa uye achiita chidimbu kubva fallopian chubhu uye dumbu, zviri safambika nenyere. Ultrassom anogona kuona zvakarurama nzvimbo nechepamberi.

Kana murwere anonzwisisa zvinoreva shoko rokuti "Ultrasound", chii uye nei chiremba wako akamuraira ongororo, hazvina kunzwa kutya, vakagadzirira kuita zvakakodzera zvinodiwa nachiremba uye zvakakodzera rinoreva nzira. Kubva ichi zvinoenderana zvinhu zvakawanda. Sezvo kazhinji, pachinzvimbo kunzvera uye kurapwa wevarwere kutya kuna nevanyengeri uye "vanoporesa", kurasikirwa nguva inokosha.
