Hoʻolauna Huahana
ʻO ka LSO:Ce scintillator he LSO crystal doped me nā ion cerium (Ce).ʻO ka hoʻohui ʻana o ka cerium e hoʻomaikaʻi i nā waiwai scintillation o LSO, e lilo ia i mea ʻike maikaʻi loa o ka radiation ionizing.LSO:Ce scintillators ua hoʻohana nui ʻia i ka Positron Emission Tomography (PET) scanners, he mea hana kiʻi lāʻau lapaʻau i hoʻohana ʻia e ʻike a mālama i nā maʻi like ʻole e like me ka maʻi kanesa, Alzheimer a me nā maʻi neurological ʻē aʻe.I loko o ka PET scanners, LSO:Ce scintillators hoʻohana ʻia e ʻike i nā kiʻi i hoʻopuka ʻia e nā radiotracers-emitting positron (e like me F-18) i hoʻokomo ʻia i loko o ka mea maʻi.Loaʻa kēia mau radiotracers i ka palaho beta, e hoʻokuʻu ana i ʻelua kiʻi ma nā ʻaoʻao ʻē aʻe.Hoʻopaʻa nā Photons i ka ikehu i loko o ka LSO:Ce crystal, e hana ana i ke kukui scintillation i hopu ʻia a ʻike ʻia e ka pahu photomultiplier (PMT).Heluhelu ka PMT i ka hōʻailona scintillation a hoʻololi iā ia i ka ʻikepili kikohoʻe, i hana ʻia e hana i kahi kiʻi o ka hāʻawi ʻana i ka radiotracer i ke kino.LSO: Hoʻohana pū ʻia nā scintillators Ce i nā noi ʻē aʻe e koi ana i nā mea ʻike scintillation hana kiʻekiʻe, e like me ke kiʻi kiʻi X-ray, physics nuklea, kiʻekiʻe-energy physics, a me radiation dosimetry.
ʻO LSO, a i ʻole ke alakaʻi scintillation oxide, he mea maʻamau i hoʻohana ʻia i ka ʻike radiation a me nā noi kiʻi.He aniani scintillation ia e ʻā ana i ka wā e ʻike ʻia ai i ka radiation ionizing e like me nā kukuna gamma a i ʻole nā kukui X.A laila ʻike ʻia ke kukui a hoʻololi ʻia i mau hōʻailona uila, hiki ke hoʻohana ʻia e hana i nā kiʻi a ʻike paha i ka hele ʻana o ka radiation.He ʻoi aku ka maikaʻi o ka LSO ma mua o nā mea scintillation ʻē aʻe, ʻo ia hoʻi ka puka māmā kiʻekiʻe, ʻoi aku ka wikiwiki o ka manawa palaho, ka hoʻonā ikehu maikaʻi, haʻahaʻa haʻahaʻa, a me ke kiʻekiʻe kiʻekiʻe.ʻO ka hopena, hoʻohana maʻamau ʻia nā kristal LSO i nā lako kiʻi lāʻau lapaʻau e like me ka PET scanners, a me nā noi palekana a me ka nānā ʻana i ke kaiapuni.
