Ukadaulo waukadaulo waukadaulo waukadaulo wamakono wakhala ukukula kwazaka zopitilira theka ku China.Ndi kupititsa patsogolo kosalekeza kwa ukadaulo wazidziwitso zamagetsi ndiukadaulo wamakompyuta, zida zodziwira akupanga zakhala zikusintha nthawi zambiri, kuyambira chizindikiro cha analogi / chakuda ndi choyera cha ultrasound / harmonic kusiyana / kuzindikira kopanga, mpaka chizindikiro cha digito / mtundu wa ultrasound / kujambula kowala / nzeru zochita kupanga.Zatsopano ntchito ndi ntchito milingo akupitiriza kukula, ndi akupanga kulingalira zida matenda akupitiriza innovative ndi kudutsa, zikupangitsa makampani azachipatala kukhala yaikulu kufunika kwa izo.
01 . Basic classification wa wamba akupanga kujambula zida matenda
Akupanga kulingalira zida zowunikira ndi mtundu wa zida zowunikira matenda zomwe zimapangidwa molingana ndi mfundo ya ultrasound.Poyerekeza ndi zida zazikulu zachipatala monga CT ndi MRI, mtengo wake woyendera ndi wotsika kwambiri, ndipo uli ndi ubwino wosasokoneza komanso nthawi yeniyeni.Choncho, ntchito yachipatala ndi yowonjezereka.Pakalipano, kufufuza kwa ultrasound kumagawidwa kukhala A-type ultrasound (one-dimensional ultrasound), B-type ultrasound (two-dimensional ultrasound), katatu-dimensional ultrasound ndi anayi-dimensional ultrasound.
Kawirikawiri amatchedwa B-ultrasound, kwenikweni amatanthauza wakuda ndi woyera awiri dimensional B-ultrasound, anasonkhanitsa fano ndi wakuda ndi woyera awiri-dimensional ndege, ndi mtundu ultrasound ndi anasonkhanitsa magazi chizindikiro, pambuyo kompyuta coding coding. chithunzi cha mbali ziwiri mu nthawi yeniyeni yapamwamba, ndiko kuti, mapangidwe a magazi a Doppler ultrasound.
Atatu-dimensional akupanga matenda zachokera mtundu Doppler akupanga matenda chida, deta kupeza chipangizo kukhazikitsidwa, ndi fano kukonzanso ikuchitika kudzera atatu azithunzithunzi mapulogalamu, kuti apange chipangizo chachipatala kuti akhoza kusonyeza azithunzithunzi atatu azithunzithunzi ntchito, kotero kuti Ziwalo za anthu zimatha kuwonetsedwa mopitilira muyeso ndipo zotupa zitha kupezeka mwachilengedwe.Mitundu inayi yamtundu wa ultrasound imachokera pamitundu itatu yamtundu wa ultrasound kuphatikiza ndi vector ya nthawi yachinayi (yapakati-dimensional parameter).
02 . Akupanga kafukufuku mitundu ndi ntchito
M'kati mwa matenda a akupanga chithunzi, kufufuza kwa akupanga ndi gawo lofunika kwambiri pazida zozindikiritsa akupanga, ndipo ndi chipangizo chomwe chimatumiza ndikulandila mafunde akupanga pakuzindikira ndi kuzindikira kwa akupanga.Kuchita kwa kafukufukuyu kumakhudza mwachindunji mawonekedwe a akupanga ndi akupanga kudziwika ntchito, kotero kafukufukuyo ndi wofunikira kwambiri pa matenda a akupanga chithunzi.
Ena ochiritsira probes mu akupanga probes makamaka monga: limodzi galasi otukukira m'makutu osiyanasiyana kafukufuku, modutsa angapo kafukufuku, liniya gulu kafukufuku, buku kafukufuku, patsekeke kafukufuku.
1, scrystal convex array probe
Chithunzi cha akupanga ndichopangidwa ndi kusakanikirana kwapafupi kwa kafukufuku ndi nsanja ya dongosolo, kotero pamakina omwewo, mapulogalamu ndi hardware ziyenera kukwaniritsa zofunikira za kafukufuku umodzi wa kristalo.
Makina amtundu umodzi wa crystal convex array amatenga gawo limodzi lofufuzira la kristalo, malo ofufuzira ndi owoneka bwino, malo olumikizirana ndi ang'onoang'ono, malo ojambulira ndi owoneka ngati fan, ndipo amagwiritsidwa ntchito kwambiri m'mimba, zakulera, mapapo ndi mbali zina zachibale. ziwalo zakuya.
Kuyeza khansa ya chiwindi
2, kufufuza kwapang'onopang'ono
Malo opangira kafukufuku ndi athyathyathya, olumikizana nawo ndi ochepa, gawo lapafupi ndi locheperako, gawo lakutali ndi lalikulu, ndipo gawo lojambula ndi lofanana ndi fan, lomwe lili loyenera mtima.
Zofufuza za mtima zimagawidwa m'magulu atatu malinga ndi chiwerengero cha anthu ogwiritsira ntchito: akuluakulu, ana, ndi makanda obadwa kumene: (1) akuluakulu ali ndi malo ozama kwambiri a mtima ndi kuthamanga kwapang'onopang'ono;(2) Malo a mtima wa khanda lobadwa kumene ndi osaya ndipo liŵiro lakugunda ndilofulumira kwambiri;(3) Mitima ya ana ili pakati pa makanda obadwa kumene ndi akuluakulu.
Kuyeza mtima
3,lkafukufuku wamtundu wina
Pamwamba pa probe ndi lathyathyathya, malo olumikizana ndi akulu, malo ojambulira ndi amakona anayi, mawonekedwe ojambulira ndi okwera, kulowa kwake kumakhala kocheperako, ndipo ndikoyenera kuyang'ana mwachiphamaso mitsempha yamagazi, ziwalo zazing'ono, minofu ndi zina zotero.
Kuyezetsa chithokomiro
4, vkufufuza kwathunthu
Pamaziko a chithunzi chamitundu iwiri, kafukufuku wa voliyumu adzasonkhanitsa mosalekeza malo ogawa malo, kudzera mu algorithm yomanganso makompyuta, kuti apeze mawonekedwe athunthu.Oyenera: nkhope ya fetal, msana ndi miyendo.
Kuyeza kwa fetal
5, kafukufuku wamkati
The intracavitary kafukufuku ali makhalidwe mkulu pafupipafupi ndi mkulu fano kusamvana, ndipo safuna kudzaza chikhodzodzo.Chofufumitsacho chili pafupi ndi malo omwe amafufuzidwa, kotero kuti chiwalo cha pelvic chili pafupi ndi malo a phokoso la phokoso, ndipo chithunzicho chikuwonekera bwino.
Kuwunika kwa endovascular ziwalo
