Nuclear Medical Imaging Solutions
Chii chinonzi Medical imaging?
Nuclear medical imaging (inonziwo radionuclide scanning) chishandiso chekuongorora chinoshanda nekuti hachingoratidzi chimiro (chimiro) chenhengo kana chikamu chemuviri, asi kushanda kwenhengo zvakare.Iyi yekuwedzera "ruzivo runoshanda" inobvumira mushonga wenyukireya kuongorora zvimwe zvirwere uye akasiyana mamiriro ekurapa nekukurumidza kupfuura mamwe maedzo ekufungidzira ekurapa ayo anopa kunyanya anatomic (yakarongeka) ruzivo nezvenhengo kana chikamu chemuviri.Mishonga yenyukireya inogona kuve yakakosha mukutanga kuongororwa, kurapwa, uye kudzivirira kweakawanda mamiriro ekurapa uye inoramba ichikura sechishandiso chine simba chekurapa.
KUNYANYA KUNYANYA ZVINOTAURA HUTANO ZVINOpa kurapwa kwekufungidzira imaging manejimendi ayo anga ari chikamu chehupenyu hwavo hwezuva nezuva kune general radiology modalities (kureva, CT, MR, X-ray, PET, SPECT, nezvimwewo).Nekudaro, nyanzvi mumasangano aya, kubva kuvarapi, tekinoroji, nevatungamiriri, kune vashandi vePACS/IT, vanga vachinzwawo marwadzo ekushaya mhinduro dzePACS dzemhando dzakasiyana siyana.Iyo yakanyanya kusashandirwa maitiro nePACS ndiyo yenyukireya molecular imaging modalities, kusanganisira PET-CT, SPECT-CT, nuclear cardiology, uye general nuclear medicine.
Kunyangwe kufungidzira kwenyukireya kwema molecular idiki tichitarisa huwandu hwebvunzo dzinoitwa pagore, kukosha kwayo hakufanirwe kurerutswa, zvese zvekiriniki uye nemari.PET-CT yakaratidza kuti ndiyo de facto modhi kana zvasvika pakuongororwa kenza.Nuclear cardiology yanga iri nzira yesarudzo yeasina kuvavasive cardiology.General nyukireya mushonga inopa akawanda anoshanda ekufungidzira maapplication ayo hapana mamwe maitiro anogona kuenderana.Nezvemari, PET-CT uye nyukireya cardiology ichiri pakati peyepamusoro akadzoserwa maitiro ekuongorora kufungidzira.
Chii chinoita kuti nyukireya yekurapa molecular imaging isiyane neyakajairwa radiology modalities ndeyekuti yekare mifananidzo inoshanda emuviri, nepo yekupedzisira inofananidzira anatomy yemuviri.Ichi ndicho chikonzero nyukireya molecular imaging dzimwe nguva inonziwo metabolic imaging.Kuti uongorore mabasa emuviri kubva pamifananidzo yakawanikwa, zvakakosha kutarisa uye kuongorora maturusi anodiwa.Zvishandiso izvi ndizvo chaizvo zvisipo kubva kuruzhinji rwePACS nhasi.
Nezveizvi, Yakawanda uye yakawanda yekurapa imaging tekinoroji kambani inoda kuvandudza chizvarwa chitsva PET, SPECT.
Sei Kusarudza Kinheng:
1.Minimal pixel dimension iripo
2.Reduced optical crosstalk
3.Kufanana kwakanaka pakati pepixel kusvika pixel/ Array kurongwa
4.TiO2/BaSO4/ESR/E60 zvinoratidzira zviripo
5.Pixel Gap: 0.08, 0.1, 0.2, 0.3mm
6.Performance yekuongorora iripo

Mechanical dhizaini yekuunganidza:
Zvichienderana nemagumo ekushandiswa kweakaungana array, kune akawanda marudzi emakanika dhizaini kubva kuKinheng kusangana neindasitiri yekuongorora yekurapa uye yekuchengetedza.
1D Liner array inonyanya kushandiswa kuSecurity inspection industy, senge Bagger scanner, Aviation scanner, 3D scanner uye NDT.Material Kusanganisira CsI(Tl), GOS:Tb/Pr Firimu, GAGG:Ce, CdWO4 scintillator etc. Zvinowanzobatanidzwa neSilicon Photodiode line array yekuverenga kunze.
2D array anowanzo shandiswa pakufungidzira, kusanganisira Medical(SPECT, PET, PET-CT, ToF-PET), SEM, Gamma kamera.Aya 2D array anowanzo kusanganiswa neSIPM array, PMT array yekuverenga kunze.Kinheng inopa 2D array kusanganisira LYSO, CsI (Tl), LSO, GAGG, YSO, CsI (Na), BGO scintillator nezvimwe.
Pazasi pane kinheng's anowanzo dhizaini dhizaini ye1D Uye 2D array yeindasitiri.
