Akupanga diagnostic chida
Ndikukula kosalekeza kwa chithunzi cha b-type ultrasound cha chithunzi cha chiwindi, m'badwo woyamba wa chithunzi chojambula pang'onopang'ono B-mtundu wa tomography wagwiritsidwa ntchito pochita zachipatala.M'badwo wachiwiri wa makina ojambulira mwachangu komanso othamanga kwambiri - liwiro lenileni lanthawi yayitali yamitundu yambiri yamagetsi opanga makina akupanga tomography scanner adawonekera.Generation, kompyuta fano processing monga kutsogolera zochita zokha, apamwamba digiri ya quantization wachinayi m'badwo wa akupanga kulingalira zida mu ntchito siteji.Pakali pano, akupanga matenda akukula kwa ukatswiri ndi luntha.
Akupanga tomography yakula kwambiri m'zaka zaposachedwa, ndipo zida zotsogola zimayikidwa m'chipatala pafupifupi chaka chilichonse.Choncho, pali mitundu yambiri ya zida, ndi zomangira zosiyanasiyana zolinga zosiyanasiyana.Pakali pano, n'zovuta kupeza akupanga tomography chida kuti akhoza kufotokoza wonse dongosolo la zosiyanasiyana zida.Mu pepala ili, titha kungopereka chidule chachidule cha zida zamtunduwu potengera zenizeni - nthawi B - mode ultrasonography monga chitsanzo.
Mfundo yofunikira ya
B-mtundu akupanga diagnostic chida (chotchedwa B-ultrasound) amapangidwa pamaziko a A-ultrasound, ndi ntchito mfundo zake n'zofanana ndi a-ultrasound, komanso ntchito kugunda echo kujambula luso.Chifukwa chake, kapangidwe kake koyambira kumapangidwanso ndi kafukufuku, kutumizira madera, kulandira dera ndi dongosolo lowonetsera.
Kusiyana kwake ndi:
① Mawonekedwe a matalikidwe amtundu wa B ultrasound amasinthidwa kukhala mawonekedwe owala a A ultrasound;
② Kusanthula kwakuya kwa nthawi kwa B-ultrasound kumawonjezedwa molunjika pawonetsero, ndipo njira yowunikira mutuwo ndi mtengo wamayimbidwe amafanana ndi kusanthula kolowera komwe kumawonekera;
③ Mu ulalo uliwonse wa ma echo sign processing ndi kukonza zithunzi, ambiri a B-ultrasound amagwiritsa ntchito makompyuta apadera a digito kuwongolera kusungirako ndi kukonza ma siginecha a digito ndikugwiritsa ntchito makina onse ojambulira, zomwe zimathandizira kwambiri mawonekedwe azithunzi.
Kuchuluka kwa ntchito pozindikira matenda
Mtundu wa B-real-time imager umagwiritsidwa ntchito pozindikira matenda motengera mawonekedwe a chithunzi cholakwika, makamaka kuphatikiza mawonekedwe azithunzi, kuwala, mawonekedwe amkati, echo yamalire, echo yonse, mawonekedwe akumbuyo a viscera ndi magwiridwe antchito a minofu yozungulira, ndi zina zambiri. mu mankhwala azachipatala.
1. Kuzindikirika kwa obereketsa ndi gynecology
Itha kuwonetsa mutu wa fetal, thupi la fetal, malo a fetal, mtima wa fetal, placenta, ectopic pregnancy, kubereka mwana wakufa, mole, anencephaly, fupa lachiberekero, ndi zina zotero.
2, ndondomeko ya ziwalo zamkati za thupi la munthu komanso kuzindikira kwa mkati mwake
Monga chiwindi, ndulu, ndulu, impso, kapamba, chikhodzodzo ndi mawonekedwe ena ndi mawonekedwe amkati;Kusiyanitsa chikhalidwe cha misa, monga kulowerera matenda nthawi zambiri alibe malire echo kapena m'mphepete si mpweya, ngati misa ali ndi nembanemba, malire echo ndi kuwonetsera yosalala;Itha kuwonetsanso ziwalo zosunthika, monga kuyenda kwa ma valve amtima.
3. Kuzindikira minofu m'ziwalo zowonekera
Kufufuza ndi kuyeza kuyanjanitsa kwazinthu zamkati monga maso, chithokomiro ndi bere.
