Hlola Amathrendi Athuthukayo kubuchwepheshe be-Digital Medical imaging

Ukuthuthukiswa kobuchwepheshe besimanje bekhompiyutha kushayela inqubekelaphambili yobuchwepheshe bezithombe zedijithali zezokwelapha. I-Molecular imaging yisihloko esisha esithuthukiswe ngokuhlanganisa ibhayoloji yamangqamuzana nesithombe sesimanje sezokwelapha. Ihlukile kubuchwepheshe be-imaging bezokwelapha bakudala. Ngokuvamile, amasu e-imaging yezokwelapha zakudala abonisa imiphumela yokugcina yezinguquko zamangqamuzana emangqamuzaneni omuntu, ethola okungavamile ngemva kokwenziwa kwezinguquko ze-anatomical. Kodwa-ke, ukuthwebula izithombe kwamangqamuzana kungabona izinguquko emangqamuzaneni asekuqaleni kwesifo ngokusebenzisa izindlela ezithile zokuhlola ezikhethekile ngokusebenzisa amathuluzi amasha nama-reagents ngaphandle kokudala izinguquko ze-anatomical, ezingasiza odokotela baqonde ukukhula kwezifo zeziguli. Ngakho-ke, futhi iyithuluzi elisizayo elisebenzayo lokuhlola izidakamizwa kanye nokuxilongwa kwezifo.

1. Inqubekelaphambili yobuchwepheshe bezithombe zedijithali obujwayelekile

1.1I-Computer Radiography (CR)

Ubuchwepheshe be-CR burekhoda ama-X-ray ngebhodi lesithombe, bujabulisa ibhodi lesithombe ngelaser, buguqule isignali yokukhanya ekhishwa ibhodi lesithombe ibe ezokuxhumana ngemishini ekhethekile, futhi ekugcineni izinqubo nezithombe ngosizo lwekhompyutha. Ihlukile emithini yendabuko yokukhipha imisebe ngokuthi i-CR isebenzisa i-IP esikhundleni sefilimu njengesithwali, ngakho ubuchwepheshe be-CR budlala indima yenguquko enqubweni yenqubekelaphambili yobuchwepheshe besimanje bomuthi wemisebe.

1.2 I-Direct Radioography (DR)

Kunomehluko othile phakathi kwezithombe ze-X-ray eziqondile kanye nemishini ye-X-ray evamile. Okokuqala, indlela yokuthwebula izithombe zefilimu ithathelwa indawo ngokuguqula ukwaziswa kube isignali engabonwa yikhompyutha ngomtshina. Okwesibili, usebenzisa umsebenzi wesistimu yekhompiyutha ukucubungula izithombe zedijithali, yonke le nqubo iwukusebenza ngogesi ngokugcwele, okunikeza ukunethezeka kohlangothi lwezokwelapha.

I-linear radiography ingahlukaniswa cishe ibe yizinhlobo ezintathu ngokuya ngemitshina ehlukene eyisebenzisayo. I-imaging yedijithali eqondile, umtshina wawo uyipuleti ye-silicon e-amorphous, uma kuqhathaniswa nokuguqulwa kwamandla angaqondile DR Ekuxazululeni kwendawo kunenzuzo kakhulu; Ukuze uthole izithombe zedijithali ezingaqondile, ama-detectors avame ukusetshenziswa yilezi: i-cesium iodide, i-gadolinium oxide yesibabule, i-cesium iodide/i-Gadolinium oxide ye-sulphur + lens/fiber optical +CCD/CMOS kanye ne-cesium iodide/Gadolinium oxide yesibabule + CMOS; Isistimu yezithombe yokuqinisa isithombe Digital X,

Umtshina we-CCD manje ususetshenziswa kabanzi ohlelweni lwedijithali lwe-gastrointestinal kanye nohlelo olukhulu lwe-angiography

2. Izinkambiso zokuthuthukiswa kobuchwepheshe obukhulu bezithombe zedijithali zezokwelapha

2.1 Inqubekelaphambili yakamuva ye-CR

1) Ukuthuthukiswa kwebhodi lezithombe. Izinto ezintsha ezisetshenziswa esakhiweni sepuleti lokuthwebula izithombe kunciphisa kakhulu isenzakalo sokuhlakazeka kwe-fluorescence, futhi ukucija kwesithombe nokulungiswa kwemininingwane kuyathuthukiswa, ngakho ikhwalithi yesithombe iye yathuthukiswa kakhulu.

2) Ukuthuthukiswa kwemodi yokuskena. Ngokusebenzisa ubuchwepheshe bokuskena ngomugqa esikhundleni sobuchwepheshe bokuskena indawo endizayo nokusebenzisa i-CCD njengomqoqi wezithombe, isikhathi sokuskena ngokusobala sifushane.

I-3) Isofthiwe yokucubungula emva kokucubungula iyaqiniswa futhi ithuthukiswe. Ngokuthuthuka kobuchwepheshe bekhompyutha, abakhiqizi abaningi bethule izinhlobo ezahlukene zesoftware. Ngokusetshenziswa kwalezi zinhlelo zokusebenza, ezinye izindawo ezingaphelele zesithombe zingathuthukiswa kakhulu, noma ukulahleka kwemininingwane yesithombe kungancishiswa, ukuze kutholwe isithombe esinethoni eyengeziwe.

I-4) I-CR iyaqhubeka nokuthuthuka ekuqondeni kokuhamba komsebenzi komtholampilo okufana ne-DR. Ngokufana nokugeleza kokusebenza kwe-DR, i-CR ingafaka isifundi ekamelweni ngalinye le-radiography noma ikhonsoli yokusebenza; Ngokufana nokukhiqizwa kwesithombe okuzenzakalelayo nge-DR, inqubo yokwakhiwa kabusha kwesithombe nokuskena nge-laser iqedwa ngokuzenzakalelayo.

2.2 Inqubekelaphambili yocwaningo lwe-DR Technology

1) Inqubekelaphambili kumfanekiso wedijithali we-silicon engeyona icrystalline kanye nezitholi zephaneli ye-amorphous selenium flat. Ushintsho oluyinhloko lwenzeka esakhiweni sokuhlelwa kwe-crystal, ngokusho kocwaningo, inaliti kanye nesakhiwo sekholomu ye-silicon ye-amorphous kanye ne-amorphous selenium inganciphisa ukuhlakazeka kwe-X-ray, ukuze ubukhali nokucaca kwesithombe kuthuthukiswe.

2) Intuthuko ekucabangeni kwedijithali kwezitholi zephaneli ye-CMOS flat. Ungqimba lukalayini we-fluorescent lomtshina oyisicaba we-CM0S lungakhiqiza imigqa ye-fluorescent ehambisana ne-X-ray yesigameko, futhi isignali ye-fluorescent ithwetshulwa yi-CMOS chip futhi ekugcineni ikhuliswe futhi icutshungulwe. Ngakho-ke, ukulungiswa kwendawo komtshina wokuhlela we-M0S kuphezulu njengo-6.1LP/m, okuwumtshina onokucaca okuphezulu kakhulu. Kodwa-ke, isivinini sokuthwebula esihamba kancane sohlelo sesiphenduke ubuthakathaka bezitholi zephaneli eyisicaba ye-CMOS.

3)Isithombe sedijithali se-CCD sesenze inqubekelaphambili. Ukuthwebula kwe-CCD kokuphathekayo, isakhiwo, nokucubungula isithombe sekuthuthukisiwe, ngokusebenzisa isakhiwo senaliti esisanda kwethulwa se-X-ray scintillator material, ukucaca okuphezulu kanye nesibuko esihlangene samandla aphezulu kanye nokugcwalisa i-coefficient ye-100% CCD chip imaging sensitivity, ukucaca kwesithombe. futhi isinqumo senziwe ngcono.

4) Ukusetshenziswa komtholampilo kwe-DR Kunamathemba abanzi. Umthamo ophansi, ukulimala okuncane kwemisebe kubasebenzi bezokwelapha kanye nempilo eyandisiwe yesevisi yocingo konke kuyizinzuzo zobuchwepheshe be-DR Imaging. Ngakho-ke, i-DR Imaging inezinzuzo ekuhlolweni kwesifuba, amathambo namabele futhi isetshenziswa kakhulu. Okunye okungalungile yintengo ephezulu uma kuqhathaniswa.

3. Ubuchwepheshe obuphambili bezithombe zedijithali zezokwelapha - imaging yamangqamuzana

I-imaging yamangqamuzana ukusetshenziswa kwezindlela zokucabanga ukuqonda ama-molecule athile ezingeni lezicubu, amaselula kanye ne-subcellular, engabonisa izinguquko ezingeni lamangqamuzana esimweni esiphilayo. Ngesikhathi esifanayo, singasebenzisa futhi lobu buchwepheshe ukuhlola ulwazi lwempilo emzimbeni womuntu okungelula ukutholakala, futhi sithole ukuxilongwa nokwelashwa okuhlobene ekuqaleni kwesifo.

4. Umkhuba wokuthuthukiswa kobuchwepheshe be-imaging digital yezokwelapha

I-imaging yamangqamuzana iyisiqondiso esiyinhloko socwaningo lobuchwepheshe be-imaging yedijithali yezokwelapha, enamandla amakhulu okuba umkhuba wokuthuthukiswa kobuchwepheshe bezithombe zezokwelapha. Ngesikhathi esifanayo, ukucabangela kwe-classical njengobuchwepheshe obujwayelekile, kusenamandla amakhulu.

I-LnkMedingumkhiqizi onguchwepheshe ekuthuthukisweni nasekukhiqizweni kwama-ejenti wokuqhathanisa nomfutho ophezulu ukuze asetshenziswe nezikena ezinkulu. Ngokuthuthukiswa kwefekthri, i-LnkMed ibambisene nenqwaba yabasabalalisi bezokwelapha basekhaya nabaphesheya kwezilwandle, futhi imikhiqizo isetshenziswe kabanzi ezibhedlela ezinkulu. Imikhiqizo nezinsizakalo ze-LnkMed zizuze ukwethenjwa yimakethe. Inkampani yethu ingahlinzeka ngamamodeli ahlukahlukene adumile wezinto ezisetshenziswayo. I-LnkMed izogxila ekukhiqizweni kweI-CT injector eyodwa,I-CT double head injector,I-MRI yokuqhathanisa injector yemidiya, Umjovo wemidiya ohlukile we-Angiography high pressurekanye nezinto ezisetshenziswayo, i-LnkMed ihlale ithuthukisa ikhwalithi ukuze ifinyelele umgomo "wokufaka isandla emkhakheni wokuxilongwa kwezokwelapha, ukuthuthukisa impilo yeziguli".
