Karaihe Whetu
(Whakairo Reihana Mata-iti)
Ngā pūoko e hangai ana ki te kanapa, mā te whakamahi i ngā kaitahuri tioata kore-ora kua whakapūmautia,e whakamahia whānuitia ana mō te kimi matūriki me te irahiko, tae atu ki roto ingā matawai tomography tukunga positron (PET).
Mā te tāpiri i ngā āhuatanga ārahi-mārama ki te karaihe, ka taea te whakatau i te taumira ā-wāhi o te pūokoka taea te whakapai ake ki te tauine mirimita, kia pai ake ai te taumira whānui o te tomograph.
Heoi, ko te tikanga tuku iho ote whakapiko-tinana i ngā pikako ngā tioata hehe tukanga uaua, utu nui, ā, he uaua hoki. Hei tāpiri, ko te wāhanga tākai me te aro o te pūokoka taea te whakararurarunā te meangā rauemi whakaata kāore e kanapa kua whakamahia.

Te Whakairo Reihana o raro i te Mata mōKaraihe Whetu
Ko tētahi atu huarahi ko te whakamahi ingā tikanga whakairo taiaho o raro i te mata (SSLE)mō ngā tioata scintillator.
Mā te arotahi i te laser ki roto i te karaihe, ka puta te weraka taea te waihanga i tētahi tauira whakahaere o ngā kapiti moroititērāmahi hei hanganga whakaata, te waihanga whai huangā pika ārahi māramame te kore e hiahiatia he wehenga tinana.
1. Kāore e hiahiatia he whakaahua ā-tinana o te karaihe,te whakaiti i te uauatanga me te utu.
2. Ka taea te whakamahi i ngā āhuatanga whatu me te āhua o ngā hanganga whakaatate whakahaere tika, e āhei ai te hoahoa i ngā āhua me ngā rahi pika ritenga.
3. Te hoahoa pānui me te pūokoka noho tonu ki te rite ki ngā rarangi pika paerewa.

Karaihe Whakairo Reiti o raro i te Mata?
Ngā Kitenga mō te SSLE Scintillation Crystal
1. Te Whakapai Ake i te Putanga o te Mārama
Mauī: Tirohanga Whānui o te Whakaata Mata Kore-ōrite o te Mata kua Whakairohia.
Matau: Te Ture Nekehanga Pika.
Te whakataurite i ngā pāorooro i waenga ingā rarangi whakairo taiaho o raro i te mata (SSLE)mengā rarangi tikangae whakaatu ana i tētahihe pai ake te putanga mārama mō te SSLE.
Tērā pea nā tete kore o ngā whakaata kirihoui waenga i ngā pika, ka hua ake te kore ōrite o te tirohanga whatu me te ngaronga o te photon.
Ko te tikanga o te whakapiki ake i te hua o te māramatangahe nui ake te mārama mō ngā pāorooro pūngao ōrite, te mea e hiahiatia ana te SSLE.
2. Te Whakarei Ake i te Wā Whakatakoto
He Pikitia o te Kiriata Whetu
He roa te karaihete pānga kino ki te wā, he mea tino nui mō ngā tono Positron Emission Tomography (PET).
Heoi, ko teteitei ake te aro o ngā tioata SSLEe āhei ai te whakamahi ingā tioata poto ake, e taea aiwhakapai ake i te whanonga o te pūnaha i te wā tika.
Kua whakaarohia hoki e ngā whakatauira he rerekē ngā āhua pika, pērā i te hexagonal, te dodecagonal rānei, ka taeaka pai ake te mahi ārahi mārama me te mahi wā, he rite ki ngā mātāpono o ngā muka whatu.
3. Ngā Painga Whai Hua
He Pikitia o te Kiriata Scintillator
Ki te whakatauritea ki ngā poraka monolithic, ko te utu o ngā tioata SSLEka taea te iti iho i tekotahi hautoruo te utuo te huinga pika e rite ana, i runga i ngā rahinga pika.
Hei tāpiritanga, ko teteitei ake te aro o ngā tioata SSLEe āhei aite whakamahi i ngā tioata poto ake, te whakaiti anō i te utu whānui.
He iti ake te mana o te taiaho e hiahiatia ana e te tikanga SSLE ki te whakataurite ki te tapahi taiaho, e taea ai tengā pūnaha SSLE iti ake te utuki te whakarite ki ngā whare rewa, tapahi rānei mā te taiaho.
Tete haumitanga tuatahi ki ngā hanganga me ngā whakangunguhe iti iho hoki te SSLEi te utu mō te whakawhanake i tētahi taputapu kite PET.
4. Ngāwari o te Hoahoa me te Whakaritenga
Ko te tukanga o te whakairo i ngā tioata SSLE kokāore e pau te wā, me te āhua tata15 menetie hiahiatia ana hei whakairo i tētahi whakarārangi karaihe-3, 12.8x12.8x12 mm.
Teāhua ngāwari, whai huatanga utu, mete ngāwari o te whakarite i ngā tioata SSLE, me ā rātouwāhanga tākai pai ake, hei utu mō tehe iti ake te taumira ā-wāhiki te whakataurite ki ngā rarangi pika paerewa.
Ngā Āhuatanga Pika Kore-Tuturu
Mā te SSLE ka taea te tūhura ingā āhuahanga pika kore-tikanga, e āhei ai ngā pika kanapa kiahe mea tino ōrite ki ngā whakaritenga motuhake o ia tono, pērā i ngā collimator, i ngā inenga rānei o ngā pika whakarea whakaahua silicon.
Te Tiritiri Mārama Whakahaeretia
Ka taea te whakatutuki i te tiritiri mārama whakahaere mā te whakahaere tika i ngā āhuatanga whatu o ngā mata whakairo,hei āwhina i te whakaitiiti ake i ngā pūoko gamma.
Ngā Hoahoa Tauhou
Ngā hoahoa tauhou, pērā i ngā Voronoi tessellations, ka taeahe ngawari te whakairo i roto i ngā tioata monolithic. Hei tāpiri atu, mā te tohatoha matapōkere o ngā rahi pika ka taea te whakauru i ngā tikanga pūoko kōpeke, me te whakamahi i te tohatoha whānui o te māramatanga.
Ngā Mīhini mō te Whakairo Taiaho o raro i te Mata
Ko te ngako o te hanga i te Subsurface Laser kei roto i te mīhini whakairo laser. Ka whakamahia e ēnei mīhinihe taiaho matomato kaha teitei, i hangaia mōwhakairo taiaho o raro i te mata i roto i te karaihe.
