Ndedzipi Dzidziso Dzichangoburwa muMedical Imaging?

Kubva zvakavamba kuma1960 kusvika kuma1980, Magnetic Resonance Imaging (MRI), computerized tomography (CT) scans, uye positron emission tomography (PET) scans zvakafambira mberi zvikuru. Aya maturusi ekufungidzira asingasviki ekurapa akaenderera mberi nekushanduka pamwe nekubatanidzwa kwehunyanzvi hwekugadzira (AI), nzira dzakagadziridzwa dzekuunganidza data mbishi, uye yakawanda-parametric nhamba yekuongorora, iyo yose inobatsira pakuvandudza kunzwisisa uye kuongororwa kwemaitiro edu emukati.

Kuvandudzwa kwePET uye CT scans

A standard PET scan inowanzoda pakati pemaminetsi makumi mana neawa kuti ipedze uye inogona kuburitsa mifananidzo yakasiyana yekukura kwebundu mukati mehuropi, mapapu, cervix, uye mamwe matunhu emuviri. Kufambira mberi kuri kuenderera mberi kwakawedzera kushanda kweiyi nzira, kubatanidza software yekufamba blur kururamisa uye kugonesa algorithmic ongororo kutarisira nzvimbo yehuwandu mukati inofamba tishu.

Motion blur inoitika kana chikamu chinotarirwa chinofamba panguva yePET scan image kutorwa, zvichiita kuti zvinyanye kunetsa kuongorora nekuongorora misa kana matishu. Kuti uderedze kufamba panguva yePET scan, vashandi vehutano vanoshandisa gated kutora, kupatsanura kutenderera kutenderera kuita "mabhini" akawanda. Nekukamura maitiro ekuongorora kuita 8-10 mabhini, chirongwa chinogona kutarisira nzvimbo yehuwandu hunotarirwa panguva yakatarwa kana nzvimbo, zvichienderana nezvinodiwa nemushandisi. Kufembera uku kunoitwa nekutarisira nzvimbo yehuwandu mukati memabhini ega ega ekutenderera. Iyo gated yePET imaging process inonyatso kudzikisa iyo inherent motion blur mumidziyo, zvichikonzera kuvandudzwa kwechiitiko chekutarisa / yakajairwa yekuvandudza kukosha (SUV). Kana iyo PET data yakabatana neCT data, iyo yese nzira inozivikanwa se4D CT scanning.

Zvakadaro, pane kucherechedzwa kuganhurirwa kunoenderana nemaitiro aya. Kushandisa magedhi nzira dzekutorwa kwemifananidzo kunokonzeresa kuwedzera ruzha nekuda kwekutorwa kwehuwandu hwakakura hwedata. Mazano akati wandei ekugadzirisa nyaya iyi anosanganisira Q-freeze, Oncofreeze, uye nguva yekubhururuka (ToF).

Kusajeka kwemufananidzo kunogadziriswa sei mukati mePET uye CT scans

Q-freeze image-based correction, uchishandisa magedhi ekutora, inosanganisira kuunganidzwa uye kunyoreswa kwemifananidzo yese yakagadzirwa. Kunyoreswa uku kunoitika mukati menzvimbo yemufananidzo, kuunganidza nekugadzirisazve data rese rakawanikwa kubva kuPET scan kuti ribudise mufananidzo wekupedzisira une ruzha rwakaderedzwa uye kusajeka.

OncoFreeze, yegirazi software tekinoroji, inofanana neQ-chando mune dzimwe nzira, kunyangwe zvakasiyana zvachose. Kugadziriswa kwekufamba kunoitwa munzvimbo ye sinogram (raw data space). Mushure mekutora mufananidzo wekutanga, iyo inotevera yakasviba mifananidzo inofungidzirwa kumberi uye ichienzaniswa nebhenji rekuvhiya rekuvhiya data uye backproject sinogram ratios. Izvi zvinotungamira kune yekupedzisira yakagadziridzwa chifananidzo chinoenderana neyakasvibiswa gadziriso mufananidzo.

Kubata mafungu ekufema panguva yePET scans yakasanganiswa neCT scans inogona kutungamira kumhando yemufananidzo. Kurongeka kwakavandudzwa kunogona kuenzanisirwa nokutsinhiranisa masaisai ePET scans, nzira yakajairika, nemasaisai eCT scans, nzira ichangobva kugadzirwa.

Sezvatinoziva tose, kusimudzirwa kweindasitiri yekufungidzira yekurapa haiparadzaniswe kubva mukugadzirwa kweakatevedzana emidziyo yekurapa - majekiseni anosiyanisa ajenti uye ayo anotsigira anobatika - ayo anoshandiswa zvakanyanya munharaunda iyi. MuChina, iyo inozivikanwa neindasitiri yayo yekugadzira, kune vagadziri vazhinji vane mukurumbira kumba nekune dzimwe nyika kugadzirwa kwemidziyo yekufungidzira yekurapa, kusanganisira.LnkMed. Kubva payakavambwa, LnkMed yanga yakatarisana nemunda weakanyanya-kudzvanya mutsauko ajenti majekiseni. Chikwata cheinjiniya cheLnkMed chinotungamirwa nePh.D. ane makore anopfuura gumi eruzivo uye akabatanidzwa zvakanyanya mukutsvaga nekusimudzira. Mukutungamirira kwake, theCT jekiseni rimwechete remusoro, CT kaviri musoro jekiseni, MRI kusiyanisa agent injector,uyeAngiography yakakwirira-kudzvanywa mumiririri jekiseniakagadzirwa aine aya maficha: iyo yakasimba uye yakabatana muviri, yakanakira uye nehungwaru mashandiro interface, mabasa akazara, kuchengetedzwa kwepamusoro, uye dhizaini yakasimba. Tinogonawo kupa majekiseni nemachubhu anofambirana neaya majekiseni ane mukurumbira eCT,MRI,DSA majekiseni Nemafungiro avo echokwadi uye simba rehunyanzvi, vashandi vese veLnkMed vanokukoka nemwoyo wose kuti uuye kuzoongorora mimwe misika pamwe chete.
