Kuvandudzwa kwehunyanzvi hwemakomputa hwemazuva ano kunofambisa kufambira mberi kwehunyanzvi hwekufungidzira hwedhijitari. Molecular imaging inyaya itsva yakagadzirwa nekubatanidza molecular biology nemifananidzo yemazuva ano yekurapa. Iyo yakasiyana neye classical medical imaging technology. Kazhinji, maitiro echinyakare ekurapa ekufungidzira anoratidza magumo ekuchinja kwemamolekyulu mumasero emunhu, kuona zvisizvo mushure mekuchinja kweanatomical kwaitwa. Nekudaro, kufungidzira kwemamorekuru kunogona kuona shanduko mumaseru padanho rekutanga rechirwere kuburikidza nedzimwe nzira dzekuyedza nekushandisa mamwe maturusi matsva nemareagents pasina kukonzera shanduko yeanatomical, inogona kubatsira vanachiremba kunzwisisa kukura kwezvirwere zvevarwere. Naizvozvo, iri zvakare chishandiso chinobatsira chekuongorora zvinodhaka uye kuongororwa kwechirwere.
1. Kufambira mberi kweiyo mainstream digital imaging tekinoroji
1.1Computer Radiography (CR)
CR tekinoroji inorekodha X-rays ine bhodhi remufananidzo, inonakidza bhodhi remufananidzo nelaser, inoshandura chiratidzo chechiedza chinoburitswa nebhodhi remufananidzo munharembozha kuburikidza nemidziyo yakakosha, uye pakupedzisira maitiro uye mifananidzo nerubatsiro rwekombuta. Yakasiyana nemushonga wemwaranzi wechinyakare pakuti CR inoshandisa IP pachinzvimbo chefirimu semutakuri, saka tekinoroji yeCR inoita basa rekuchinja mukufambira mberi kwehunyanzvi hwekurapa kwemwaranzi.
1.2 Direct Radiography (DR)
Pane misiyano pakati peiyo yakananga X-ray kutora mifananidzo uye yechinyakare X-ray michina. Kutanga, nzira yephotosensitive imaging yefirimu inotsiviwa nekushandura ruzivo muchiratidzo chinogona kuzivikanwa nekombiyuta ne detector. Chechipiri, kushandisa basa rekombuta yekugadzira mifananidzo yedhijitari, iyo nzira yese ndeyekuzara kwemagetsi kushanda, izvo zvinopa nyore kune yekurapa divi.
Linear radiography inogona kukamurwa kuita mhando nhatu zvichienderana neakasiyana madhijitari aanoshandisa. Yakananga dhijitari imaging, detector yayo is amorphous silicon plate, ichienzaniswa neyakajeka simba shanduko DR Mukugadzirisa kwepakati kunobatsira zvakanyanya; Nokuda kwekufungidzira kwedhijitari isina kunanga, zvigadziriswe zvinowanzoshandiswa ndezvi: cesium iodide, gadolinium oxide yesulfure, cesium iodide / Gadolinium oxide yesulfure + lens / optical fiber + CCD / CMOS uye cesium iodide / Gadolinium oxide yesulfure + CMOS; Image intensifier Digital X mafoto system,
CCD detector ikozvino inoshandiswa zvakanyanya mu digital gastrointestinal system uye hombe angiography system
2. Mafambiro ekuvandudza ezvekurapa digitaalinen imaging technologies
2.1 Kufambira mberi kweCR
1) Kuvandudzwa kwe imaging board. Zvinhu zvitsva zvinoshandiswa mukugadzirwa kweplate yekufungidzira zvinoderedza zvakanyanya fluorescence kuparadzira chiitiko, uye kupinza kwemufananidzo uye tsanangudzo yekugadzirisa kunovandudzwa, saka kunaka kwemufananidzo kwakavandudzwa zvakanyanya.
2) Kuvandudzwa kwekutarisa maitiro. Uchishandisa tekinoroji yekutarisa tekinoroji panzvimbo yekubhururuka nzvimbo yekuongorora tekinoroji uye kushandisa CCD semuunganidzi wemifananidzo, nguva yekuongorora inopfupikiswa.
3) Post-processing software inosimbiswa uye inovandudzwa. Nekuvandudzwa kwekombuta tekinoroji, vagadziri vazhinji vakaunza mhando dzakasiyana dzesoftware. Kuburikidza nekushandiswa kweiyi software, dzimwe nzvimbo dzisina kukwana dzechifananidzo dzinogona kuvandudzwa zvakanyanya, kana kurasikirwa kweiyo tsanangudzo yemufananidzo kunogona kuderedzwa, kuitira kuti uwane imwe toni mufananidzo.
4) CR inoramba ichikura munzira yekufambiswa kwekiriniki yakafanana neDR. Zvakafanana neiyo decentralized workflow yeDR, CR inogona kuisa muverengi mune yega yega radiography kamuri kana inoshanda console; Zvakafanana neiyo otomatiki mufananidzo chizvarwa neDR, maitiro ekuvakazve mufananidzo uye laser scanning inopera otomatiki.
2.2 Kufambira mberi kwekutsvagisa kweDR Technology
1) Kufambira mberi mukufungidzira kwedhijitari yesilicon isina-crystalline uye amorphous selenium flat panel detectors. Shanduko huru inoitika muchimiro chekristaro kurongeka, maererano nekutsvaga, tsono uye columnar chimiro cheamorphous silicon uye amorphous selenium inogona kuderedza X-ray kupararira, kuitira kuti kupinza uye kujeka kwechifananidzo kuvandudzwe.
2) Kufambira mberi mukufungidzira kwedhijitari yeCMOS flat panel detectors. Iyo fluorescent line layer yeCM0S flat detector inogona kugadzira mitsara yefluorescent inoenderana nechiitiko X-ray danda, uye chiratidzo chefluorescent chinotorwa neCMOS chip uye pakupedzisira inokwidziridzwa uye kugadziriswa. Nokudaro, kugadziriswa kwenzvimbo yeM0S planar detector yakakwirira se 6.1LP/m, inova detector ine sarudzo yepamusoro. Nekudaro, iyo inononoka yekufungidzira kumhanya kweiyo sisitimu yave kushaya simba kweCMOS flat panel detectors.
3) CCD digital imaging yafambira mberi. Kufungidzira kweCCD mune zvinhu, chimiro, uye kugadzirisa kwemifananidzo kwakagadziridzwa, isu kuburikidza neyakangoburitswa tsono chimiro cheX-ray scintillator zvinhu, kujeka kwepamusoro uye yakakwirira simba optical musanganiswa girazi uye kuzadza coefficient ye100% CCD chip imaging senitivity, kujeka kwemufananidzo. uye sarudzo yakagadziridzwa.
4) Kushandiswa kwekliniki yeDR Iine tarisiro yakakura. Kuderera kwedosi, kushomeka kukuvadzwa kwemwaranzi kune vashandi vekurapa uye yakawedzera hupenyu hwesevhisi yechishandiso zvese zvakanakira DR Imaging tekinoroji. Naizvozvo, DR Imaging ine zvakanakira muchipfuva, bhonzo uye mazamu kuongororwa uye inoshandiswa zvakanyanya. Zvimwe zvisingabatsiri mutengo wakaderera.
3. Iyo yekucheka-kumucheto tekinoroji yekurapa digital imaging - molecular imaging
Molecular imaging ndiko kushandiswa kwemaitiro ekufungidzira kuti anzwisise mamwe mamorekuru pamatishu, cellular uye subcellular level, iyo inogona kuratidza shanduko padanho remamorekuru munzvimbo yekurarama. Panguva imwecheteyo, isu tinogona zvakare kushandisa tekinoroji iyi kuongorora ruzivo rwehupenyu mumuviri wemunhu zvisiri nyore kuwanikwa, uye kuwana kuongororwa uye kurapwa kwakabatana mukutanga kwechirwere.
4. Kuvandudza maitiro ezvokurapa digital imaging teknolojia
Molecular imaging ndiyo huru yekutsvagisa nzira yekurapa dhijitari imaging tekinoroji, ine mukana mukuru wekuve maitiro ekusimudzira ekurapa imaging tekinoroji. Panguva imwecheteyo, classical imaging seyakanyanya tekinoroji, ichine kugona kukuru.

LnkMedmugadziri ane hunyanzvi mukuvandudza uye kugadzira majekiseni emagetsi ekusiyanisa ajenti kuti ashandiswe nema scanner mahombe. Nekuvandudzwa kwefekitari, LnkMed yakashanda pamwe nevakawanda vekuparadzira vekurapa vekumba nekumhiri kwemakungwa, uye zvigadzirwa zvakashandiswa zvakanyanya muzvipatara zvikuru. Zvigadzirwa zveLnkMed nemasevhisi akahwina kuvimba kwemusika. Kambani yedu inogonawo kupa akasiyana-siyana akakurumbira emhando dzekushandisa. LnkMed ichatarisa kugadzirwa kweCT jekiseni rimwe chete,CT kaviri musoro jekiseni,MRI inosiyanisa media injector, Angiography high pressure kusiyanisa media injectoruye zvinoshandiswa, LnkMed inogara ichivandudza hutano hwekuzadzisa chinangwa che "kubatsira mumunda wekuongororwa kwechiremba, kuvandudza hutano hwevarwere".
