Debugging ye ultrasonic imaging diagnostic instrument
Ultrasonic imaging yakashandiswa zvakanyanya mukuongororwa kwekuvhiyiwa, moyo, oncology, gastroenterology, ophthalmology, obstetrics uye gynecology nezvimwe zvirwere.Mumakore achangopfuura, kune rumwe rutivi, kuvandudzwa kweiyo ultrasonic imaging diagnostic instrument inogara ichiongorora kiriniki yezvitsva zvitsva, kune rumwe rutivi se ultrasound imaging mukuongororwa kwechiitiko uye kunzwisisa kwekuita kwe ultrasonic imaging instrument, vanachiremba uye basa. muhutano hwe ultrasonic imaging diagnostic instrument uye inowanzoisa mberi zvakasiyana-siyana zvinodiwa uye Mazano, kuitira kuti kwete kungokurudzira ultrasonography diagnosis level inowedzera zvisingaregi, Uyezve, kushandiswa kwe ultrasonic imaging kwakadzika, uye teknolojia yekuongorora ye ultrasonic imaging yakagadzirwa. .
1. Monitor debugging
Kuti uwane mufananidzo wepamusoro wehutano hwekuongorora, mamiriro akasiyana-siyana anodiwa.Pakati pavo, iyo debugging ye ultrasonic diagnostic instrument yekutarisa yakakosha.Mushure mekunge mugadziri uye wekutarisa aiswa simba, mufananidzo wekutanga unoratidzwa pachiratidziri.Tarisa uone kana ribhoni yegrey yakwana usati wagadzirisa, uye isa post-processing mune mutsara mamiriro.Musiyano uye Chiedza chemonitor chinogona kugadziridzwa zvakanyanya sezvaunoda.Gadzirisa monikirii kuti iite yakakodzera, kunyangwe ichiratidza zvakaringana ruzivo rwakasiyana-siyana rwekuongorora rwakapihwa neanotambira, uye rinogamuchirwa nechiratidzo chemuongorori.Iyo greyscale inoshandiswa seyakajairwa panguva yekugadzirisa, kuitira kuti iyo yakaderera greyscale isingaoneki mune nhema.Iyo yepamusoro grey nhanho kuchena hunhu kupenya asi kupenya, gadzirisa kune ese grey level akapfuma uye anogona kuratidzwa.
2. Sensitivity debugging
Sensitivity inoreva kugona kweiyo ultrasound diagnostic chiridzwa kuona uye kuratidza chimiro chekuratidzira.Iyo inosanganisira kuwana kwakazara, padhuze kudzvanywa kwemunda uye kure kure muripo kana kudzika kuwana muripo (DGC).Iyo yakazara pfuma inoshandiswa kugadzirisa kukwidziridzwa kwemagetsi, ikozvino kana simba reiyo yakagamuchirwa chiratidzo cheiyo ultrasonic diagnostic chiridzwa.Chiyero chekuwana chizere chinokanganisa zvakananga kuratidzwa kwechifananidzo, uye kugadzirisa kwayo kwakakosha.Kazhinji, chiropa chevanhu vakuru chakajairika chinosarudzwa semuenzaniso wekugadzirisa, uye iyo chaiyo-nguva chifananidzo chechiropa chekurudyi chine yepakati hepatic vein uye yekurudyi hepatic vein inoratidzwa ne subcostal oblique incision, uye kuwanda kwese kunogadziriswa kuitira kuti echo kusimba kwechiropa. parenchyma iri pakati pechifananidzo (4-7cm nzvimbo) iri padyo sezvinobvira kune grey scale inoratidzwa pakati pegrey scale.Kudzika kuwana muripo (DGC) inozivikanwawo senguva yekuwana muripo (TGC), senitivity nguva yekugadzirisa (STC).Sezvo chinhambwe chechiitiko ultrasonic wave chinowedzera uye chichiderera mukupararira kwemuviri wemunhu, chiratidzo chepedyo-munda chinowanzo kusimba, nepo kure-kumunda chiratidzo chisina kusimba.Kuti uwane mufananidzo wekudzika yunifomu, pedyo nekudzvinyirira kwemunda uye kure kure muripo unofanirwa kuitwa.Rudzi rwega rwega rwechiridzwa cheultrasonic chinowanzotora marudzi maviri emuripo mafomu: zoning control type (slope control type) uye subsection control type (distance control type).Chinangwa chayo ndechekuita maungira emunda uri padyo (tishu isina kudzika) uye munda uri kure (tishu yakadzika) padyo nenzvimbo yegrey yemunda wepakati, ndiko kuti, kuwana mufananidzo wakafanana kubva pachiedza kusvika kune yakadzika grey pamwero, kuitira kufambisa kududzira uye kuongororwa kwevanachiremba.
3. Kugadziriswa kwehuwandu hwemasimba
Dynamic range (inotsanangurwa muDB) inoreva huwandu hweiyo yakaderera kusvika kune yepamusoro echo chiratidzo chinogona kukwidziridzwa neamplifier ye ultrasonic imaging diagnostic instrument.Iyo echo chiratidzo inoratidzwa pamufananidzo pazasi peiyo shoma haina kuratidzwa, uye iyo echo chiratidzo pamusoro peiyo yepamusoro haichagadziriswi.Parizvino, iyo ine simba renji yeakasimba uye yakaderera echo masiginecha mune yakajairika ultrasonic imaging diagnostic mudziyo ndeye 60dB.ACUSONSEQUOIA computerized ultrasound muchina unosvika 110dB.Chinangwa chekugadzirisa dhizaini ndeyekuwedzera zvizere echo siginecha ine yakakosha yekuongorora kukosha uye kumanikidza kana kudzima iyo isina kukosha yekuongorora chiratidzo.Iyo ine simba renji inofanirwa kuchinjika zvakasununguka zvinoenderana nezvinodiwa zvekuongorora.
Iyo yakakodzera dhizaini yakasarudzika sarudzo haifanire kungoita kuonesa kuratidzwa kweyakaderera uye isina simba echo chiratidzo mukati mechironda, asi zvakare simbisa iyo yakakurumbira yemuganho wekukuvadza uye echo yakasimba.Iyo general dynamic range inodiwa kuti abdominal ultrasound kuongororwa ndeye 50 ~ 55dB.Zvisinei, nokuda kwekuchenjerera uye kwakazara kutarisa uye kuongororwa kwehutachiona hwehutachiona, hukuru hunochinja hunogona kusarudzwa uye mutsauko wemufananidzo unogona kuderedzwa kuti upfumise ruzivo rwekuongorora runoratidzwa mumufananidzo we acoustic.
4. Kugadziriswa kwedanda rinotarisa basa
Kuongorora matishu emunhu ane yakatariswa acoustic danda kunogona kuvandudza kugadziriswa kweiyo ultrasound pane yakanaka chimiro chekutarisa nzvimbo (lesion), uye kuderedza chizvarwa cheultrasonic artifacts, nokudaro kuvandudza kunaka kwemufananidzo.Parizvino, ultrasonic focusing inonyanya kutora musanganiswa weiyo chaiyo-nguva dynamic electron focusing, variable aperture, acoustic lens uye concave crystal tekinoroji, kuitira kuti kuratidzira uye kugashira kwe ultrasonic kukwanise kuwana huwandu hwakazara hwekutarisisa zvakanyanya mukati mepedyo, pakati uye kure. minda.Kune iyo ultrasonic diagnostic instrument ine basa re segmentalized kutarisa kusarudzwa, kudzika kwekutarisa kunogona kugadziriswa nevarapi chero nguva panguva yekushanda.
