He aha ka Lapaʻau kiʻi?
ʻO ke kiʻi lāʻau nuklear (i kapa ʻia ʻo radionuclide scanning) he mea hana diagnostic pono no ka mea ʻaʻole ia e hōʻike wale i ke anatomy (kūkulu) o kahi okana a i ʻole ʻāpana kino, akā i ka hana o ke kino pū kekahi.ʻO kēia "ʻike hana" hou e hiki ai i ka lāʻau nuklea ke ʻike i kekahi mau maʻi a me nā ʻano olakino like ʻole ma mua o nā hoʻokolohua kiʻi lāʻau ʻē aʻe e hāʻawi ana i ka ʻike anatomic (structural) e pili ana i kahi ʻāpana a i ʻole ʻāpana kino.Hiki ke waiwai nui ka lāʻau nuklea i ka ʻike mua ʻana, ka mālama ʻana, a me ka pale ʻana i nā kūlana olakino he nui a hoʻomau i ka ulu ʻana ma ke ʻano he lāʻau lapaʻau ikaika.
NO KA NUI HANA OLA e hoʻolako ana i ka hoʻokele kiʻi diagnostic diagnostic i ʻāpana o ko lākou ola i kēlā me kēia lā no nā ʻano radiology maʻamau (ie, CT, MR, X-ray, PET, SPECT, etc.).Eia nō naʻe, ʻo ka poʻe ʻoihana i kēia mau keʻena, mai nā kauka, nā ʻenehana, a me nā luna hoʻomalu, i nā limahana PACS/IT, ua ʻike pū i ka ʻeha o ka loaʻa ʻole ʻana o nā hoʻonā PACS kūpono no nā ʻano hana like ʻole.ʻO nā ʻano hana ʻoi loa i lawelawe ʻia e PACS ʻo ia nā ʻano hana kiʻi nuklear molecular imaging, me ka PET-CT, SPECT-CT, nuclear cardiology, a me ka lāʻau nuklea maʻamau.
ʻOiai he liʻiliʻi liʻiliʻi ke kiʻi ʻoniʻoni nuklea e noʻonoʻo ana i ka nui o nā hoʻokolohua i hana ʻia i kēlā me kēia makahiki, ʻaʻole e hoʻohaʻahaʻa ʻia kona koʻikoʻi, ma ke kino a me ke kālā.Ua hōʻike ʻia ʻo PET-CT i ka de facto modality i ka wā e pili ana i ka maʻi kanesa.ʻO ka cardiology nuklear ke ʻano o ke koho no ka cardiology noninvasive.Hāʻawi ka lāʻau lapaʻau nuklea nui i nā noi kiʻi hana ʻaʻole hiki ke hoʻohālikelike i nā ʻano hana ʻē aʻe.Ma ke kālā, ʻo PET-CT a me ka cardiology nuklea aia nō i waena o nā kaʻina hana kiʻekiʻe i uku ʻia i ka diagnostic imaging.
He aha ka mea e ʻokoʻa ai ke kiʻi lāʻau lapaʻau nuklear mai nā ʻano radiology maʻamau ʻo ia nā kiʻi mua i nā hana o ke kino, ʻoiai nā kiʻi hope i ke anatomy o ke kino.ʻO ia ke kumu i kapa ʻia ai ke kiʻi mole nuklear i kekahi manawa he metabolic imaging.No ka hoʻopaʻa ʻana i nā hana o ke kino mai nā kiʻi i loaʻa, pono ke nānā pono a me nā mea hana loiloi.ʻO kēia mau mea hana ka mea i nalowale mai ka hapa nui o ka PACS i kēia lā.
E pili ana i kēia, ʻoi aku ka nui o ka ʻoihana ʻenehana imaging e makemake e hoʻomohala i ka hanauna hou PET, SPECT.
No ke aha e koho ai iā Kinheng:
1. Loaʻa ka nui pixel liʻiliʻi
2.Reduced optical crosstalk
3.Maikaʻi like ʻole ma waena o ka pixel i ka pixel / Array i ka array
4.TiO2/BaSO4/ESR/E60 reflectors loaʻa
5.Pixel Gap: 0.08, 0.1, 0.2, 0.3mm
Loaʻa ka hoʻokolohua 6.Performance

Hoʻolālā mīkini no ka hui ʻana:
Ma muli o ka hoʻohana hope ʻana o ka hui pū ʻana, nui nā ʻano hoʻolālā mechanic mai Kinheng e hālāwai me ka ʻoihana nānā olakino a palekana.
Hoʻohana nui ʻia ka 1D Liner array no Security inspection industy, e like me Bagger scanner, Aviation scanner, 3D scanner a me NDT.Mea Me CsI(Tl), GOS:Tb/Pr Film, GAGG:Ce, CdWO4 scintillator etc. Ua hui pinepine ia me ka laina laina Silicon Photodiode no ka heluhelu ana.
Hoʻohana maʻamau ʻia nā ʻano 2D no ke kiʻi kiʻi, me ka Lapaʻau (SPECT, PET, PET-CT, ToF-PET), SEM, kāmele Gamma.Hoʻohui pinepine ʻia kēia mau 2D me ka SIPM array, PMT array no ka heluhelu ʻana.Hāʻawi ʻo Kinheng i nā ʻāpana 2D me LYSO, CsI (Tl), LSO, GAGG, YSO, CsI (Na), BGO scintillator etc.
Aia ma lalo ke kiʻi hoʻolālā maʻamau a kinheng no 1D a me 2D array no ka ʻoihana.
