Hika Whakamarama – Moatai-Tautua LSO(Ce) Tioata mo te Whakanuia te Tairongo Turanga
Te whakauru o te pouaka angiangi
Ko ta tatou tioata LSO(Ce) e tohu ana i te tihi o te hangarau whakangao, he tino mahi i roto i te tini o nga tono. He mea hanga ma te tino tika me te tohungatanga, ka whakakiia tenei karaihe ki te cerium (Ce) hei whakarei ake i te pai o te whakaputanga marama me te whakautu hihiko.
Ko te karaihe LSO(Ce) e whakanui ana i te taumira o te kaha me nga ahuatanga o te waa, he mea tino pai mo te positron emission tomography (PET), gamma-ray spectroscopy, me etahi atu whakaahua rongoa me nga tono rapunga hihi. Ko te nui o te marama me te tere o te wa pirau ka whakarite kia tika, kia pono hoki te kitenga o nga hihi gamma me etahi atu iraruke katote.
Na tana mahi tino pai me te pono, ka whakatakotohia e to tatou karaihe LSO(Ce) he paerewa hou mo nga rawa scintillation, e taea ai te ahu whakamua i roto i te rangahau pūtaiao, te tātari rongoa, me te haumarutanga whenua. Ka wheako i te tairongo me te tino tika me to tatou karaihe LSO(Ce), e akiaki ana i nga mahi auaha me te kitenga i nga momo mara.
