Phonononga iiTrendi eziguqukayo kwiTekhnoloji yeDigital Medical imaging

Uphuhliso lobuchwephesha bekhompyuter banamhlanje buqhuba inkqubela phambili yetekhnoloji yemifanekiso yezonyango yedijithali. I-Molecular imaging sisifundo esitsha esiphuhliswe ngokudibanisa ibhayoloji yemolekyuli nemifanekiso yezonyango yanamhlanje. Yahlukile kwi-classical imaging technology yezonyango. Ngokuqhelekileyo, ubuchule bokucinga bezonyango beklasiki bubonisa iziphumo zokuphela kweenguqu ze-molekyuli kwiiseli zomntu, ukufumanisa izinto ezingaqhelekanga emva kokuba utshintsho lwe-anatomical lwenziwe. Nangona kunjalo, i-imaging ye-molekyuli inokubona utshintsho kwiiseli kwisigaba sokuqala sesifo ngokusebenzisa iindlela zovavanyo ezikhethekileyo ngokusebenzisa izixhobo ezitsha kunye nee-reagents ngaphandle kokubangela utshintsho lwe-anatomical, olunokunceda oogqirha baqonde ukukhula kwezifo zezigulane. Ke ngoko, sisixhobo esincedisayo esisebenzayo sovavanyo kunye nokuxilongwa kwezifo.

1. Inkqubela phambili yobuchwephesha bomfanekiso wedijithali

1.1Iradiyografi yeKhompyutha (CR)

I-CR iteknoloji irekhoda i-X-rays ngebhodi yomfanekiso, ivuyisa ibhodi yomfanekiso nge-laser, iguqula isignali yokukhanya ekhutshwe yibhodi yomfanekiso kwi-telecommunications ngokusebenzisa izixhobo ezikhethekileyo, kwaye ekugqibeleni iinkqubo kunye nemifanekiso ngoncedo lwekhompyutha. Yahlukile kumayeza emveli okutshiza ngokuba i-CR isebenzisa i-IP endaweni yefilimu njengomthwali, ngoko ke itekhnoloji yeCR idlala indima yotshintsho kwinkqubo yenkqubela phambili yetekhnoloji yeyeza langoku.

1.2 IRadiyografi eNgqo (DR)

Kukho umahluko phakathi kokufota ngokuthe ngqo kweX-reyi kunye noomatshini beX-reyi besintu. Okokuqala, indlela yokwenza umfanekiso-ngqondweni wefilimu ithatyathelw’ indawo ngokuguqula ulwazi lube ngumqondiso onokubonwa yikhompyutha ngumtshina. Okwesibini, ukusebenzisa umsebenzi wenkqubo yekhompyutheni ukucubungula imifanekiso yedijithali, yonke le nkqubo isebenza ngokupheleleyo ngombane, obonelela ngokulula kwicala lezonyango.

Umgca weradiyografi unokwahlulwa ngokweendidi ezintathu ngokwezixhobo zokubona ezahlukeneyo ezisebenzisayo. I-imaging yedijithali ngokuthe ngqo, i-detector yayo yi-amorphous silicon plate, xa kuthelekiswa nokuguqulwa kwamandla angangqalanga DR Kwisisombululo sendawo kunenzuzo ngakumbi; Kwimifanekiso yedijithali engathanga ngqo, ii-detectors ezisetyenziswa ngokuqhelekileyo zezi: i-cesium iodide, i-gadolinium oxide yesulfure, i-cesium iodide / i-Gadolinium oxide yesulfure + i-lens / i-fiber optical + CCD / CMOS kunye ne-cesium iodide / i-Gadolinium oxide yesulfure + CMOS; Inkqubo yokufota yeDijithali X,

Umtshina weCCD ngoku usetyenziswa ngokubanzi kwinkqubo yedijithali yesisu kunye nenkqubo enkulu ye-angiography

2. Iindlela zophuhliso lwetekhnoloji enkulu yonyango lwedijithali

2.1 Inkqubela phambili yamva nje yeCR

1) Ukuphuculwa kwebhodi yemifanekiso. Izinto ezintsha ezisetyenziswe kwisakhiwo sepleyiti yokucinga kunciphisa kakhulu i-fluorescence yokusabalalisa isiganeko, kunye nobukhali bomfanekiso kunye nesisombululo seenkcukacha ziphuculwe, ngoko umgangatho womfanekiso uphuculwe kakhulu.

2) Ukuphuculwa kwendlela yokuskena. Ukusebenzisa itekhnoloji yokuskena umgca endaweni yokubhabha itekhnoloji yokuskena indawo kunye nokusebenzisa iCCD njengomqokeleli wemifanekiso, ixesha lokuskena ngokucacileyo lifutshane.

I-3) I-post-processing software iqiniswa kwaye iphuculwe. Ngokuphuculwa kobuchwepheshe bekhompyuter, abavelisi abaninzi baye bazisa iintlobo ngeentlobo zesoftware. Ngokusetyenziswa kwezi software, ezinye iindawo ezingafezekanga zomfanekiso zinokuphuculwa kakhulu, okanye ukulahleka kweenkcukacha zomfanekiso kungancitshiswa, ukuze kufumaneke umfanekiso onetoni.

I-4) I-CR iyaqhubeka nokuphuhlisa kwicala lokuhamba kwekliniki efana ne-DR. Ngokufana nokuhamba komsebenzi we-DR, i-CR inokufaka umfundi kwigumbi ngalinye le-radiography okanye i-console yokusebenza; Ngokufana nokuveliswa komfanekiso ngokuzenzekelayo ngu-DR, inkqubo yokwakhiwa kwakhona komfanekiso kunye ne-laser scanning igqitywe ngokuzenzekelayo.

2.2 Inkqubela yophando lweDR Technology

I-1) Inkqubela phambili kwi-imaging yedijithali ye-silicon engeyi-crystalline kunye ne-amorphous selenium flat panel detectors. Utshintsho oluphambili lwenzeka kwisakhiwo sokucwangciswa kwe-crystal, ngokutsho kophando, inaliti kunye nesakhiwo se-columnar ye-silicon ye-amorphous kunye ne-amorphous selenium inokunciphisa ukuchithwa kwe-X-ray, ukwenzela ukuba ubukhali kunye nokucaca komfanekiso kuphuculwe.

2) Ukuqhubela phambili kwi-imaging yedijithali yee-CMOS flat panel detectors. Uluhlu lomgca we-fluorescent we-CM0S i-flat detector inokuvelisa imigca ye-fluorescent ehambelana nesiganeko se-X-ray beam, kwaye isignali ye-fluorescent ibanjwe yi-chip ye-CMOS kwaye ekugqibeleni ikhuliswe kwaye iqhutywe. Ngoko ke, isisombululo sesithuba se-M0S somtshini weplani siphezulu njenge-6.1LP / m, esiyi-detector enesisombululo esiphezulu. Nangona kunjalo, isantya esicothayo somfanekiso wenkqubo iye yaba bubuthathaka beCMOS yokubona ipaneli ecaba.

3)Umfanekiso wedijithali weCCD wenze inkqubela phambili. Umfanekiso weCCD kwizinto eziphathekayo, ulwakhiwo, kunye nokulungiswa komfanekiso kuye kwaphuculwa, thina ngokusebenzisa isakhiwo senaliti esandula kuqaliswa se-X-ray scintillator imathiriyeli, ukucaca okuphezulu kunye nesipili esidityanisiweyo samandla aphezulu kunye nokuzalisa i-coefficient ye-100% ye-CCD chip yobuntununtunu, ukucaca komfanekiso. kwaye isisombululo siphuculwe.

I-4) Ukusetyenziswa kweklinikhi ye-DR Kunamathuba abanzi. Idosi ephantsi, umonakalo omncinci wotshiso lwemitha kubasebenzi bezonyango kunye nobomi benkonzo eyandisiweyo yesixhobo zonke ziluncedo zobuchwepheshe be-DR Imaging. Ngoko ke, i-DR Imaging ineenzuzo kwisifuba, ithambo kunye nokuhlolwa kwebele kwaye isetyenziswa ngokubanzi. Ezinye izinto ezingeloncedo lixabiso eliphezulu ngokwentelekiso.

3. Itekhnoloji ye-cutting-edge ye-medical imaging digital - imaging molecular

I-molecular imaging kukusetyenziswa kweendlela zokucinga ukuqonda iamolekyu ezithile kwi-tissue, i-cellular kunye ne-subcellular level, engabonisa utshintsho kwinqanaba le-molecular kwimeko ephilayo. Kwangaxeshanye, sinokusebenzisa le teknoloji ukuphonononga ulwazi lobomi kumzimba womntu ongekho lula ukufunyanwa, kwaye ufumane ukuxilongwa kunye nonyango oluhambelanayo kwinqanaba lokuqala lesi sifo.

4. Intsingiselo yophuhliso lweteknoloji yedijithali yonyango

Ukucinga ngemolekyuli lolona khokelo lophando lwetekhnoloji yonyango lwedijithali, enesakhono esikhulu sokuba yindlela yophuhliso lwetekhnoloji yemifanekiso yezonyango. Ngexesha elifanayo, ukucinga kweklasikhi njengeteknoloji eqhelekileyo, kusenamandla amakhulu.
