Kilikole Scintillation
(Ke kālai ʻia ʻana ma lalo o ka honua)
Scintillation-based detectors, me ka hoʻohana ʻana i nā scintillator kristal inorganic pixelatedhoʻohana nui ʻia no ka ʻike ʻana i ka ʻāpana a me ka radiation, komo ilokopositron emission tomography (PET) scanners.
Ma ka hoʻohui ʻana i nā hiʻohiʻona alakaʻi māmā i ke aniani, ka hoʻonā spatial o ka mea ʻikehiki ke hoʻomaikaʻi ʻia i ka unahi millimeter, hoʻonui i ka hoʻonā holoʻokoʻa o ka tomograph.
Eia naʻe, ke ʻano kuʻuna opikela kinoʻo nā kristal he apaʻakikī, pipiʻi, a hana hana. Eia kekahi, ʻo ka hakina packing a me ka naʻau o ka mea ʻikehiki ke hoʻololima muli o kahoʻohana ʻia nā mea hoʻonaninani non-scintillating.

Ke kālai ʻia ʻana ma lalo o ka honua noKilikole Scintillation
ʻO kahi ala ʻē aʻe ka hoʻohana ʻana inā ʻenehana laser engraving (SSLE).no nā kristal scintillator.
Ma ka nānā ʻana i kahi laser i loko o ke aniani, ua hana ka welahiki ke hana i kahi ʻano hoʻomalu o microcrackskēlāhana e like me ka noonoo ana, hana pononā pika alakaʻi māmāme ka pono ole o ke kaawale kino.
1. ʻAʻole koi ʻia ka pixelation kino o ke aniani,e hōʻemi ana i ka paʻakikī a me ke kumukūʻai.
2. ʻO nā hiʻohiʻona optical a me ka geometry o nā hale hoʻohālike hiki kekaohi pono ia, hiki ke hoʻolālā i nā ʻano pixel maʻamau a me nā nui.
3. Heluhelu a me ka mea ike makae hoʻomau like me nā pūʻulu pixelated maʻamau.
Ke Kaʻina Hoʻokalakala Laser (SSLE) no ka Crystal Scintillator
ʻO ke kaʻina hana engraving SSLEnā ʻanuʻu:
1. Ka manao:
Simulation a me ka hoʻolālā o kai makemake ʻia ʻo pixel architecture, meana anaanā hiʻohiʻona optical.
2. ʻO ke kumu hoʻohālike CAD:
Ka hana ʻana o akŘkohu CAD kiko'īo ka puunaue microcrack,ma muli o nā hopena hoʻohālikeanā kikoʻī engraving laser.
3. E hoʻomaka i ke kahakaha ʻana:
ʻO ke kahakaha maoli ʻana o ka kristal LYSO me ka hoʻohana ʻana i ka ʻōnaehana laser,alakaʻi ʻia e ke kumu hoʻohālike CAD.
Ke Kaʻina Hana Hoʻomohala SSLE: (A) Ke Ana Hoʻohālike, (B) Ke Ana Hoʻohālike CAD, (C) LYSO i kahakaha ʻia, (D) Ke kiʻi kiʻi o ka wai.
4. Ka Loiloi Hua:
Ka loiloi ʻana i ka hana a ke aniani i kahakaha ʻia me ka hoʻohana ʻana i akiʻi kahua waikaheaʻO Gaussian kūponoe loiloi i ka maikaʻi o ka pixel a me ka hoʻonā spatial.
Ua wehewehe ʻia ke kahakaha ʻana ma lalo o ka honua i 2 mau minuke
ʻO kaʻenehana kālai laser ma lalo o ka ʻāinano ka mea, hāʻawi nā kristal scintillator ahoʻololi hoʻololii ka pixelation o keia mau mea.
Ma ka hāʻawi ʻana i ka mana pololei ma luna o nā hiʻohiʻona optical a me ka geometry o nā hale hoʻohālikelike, kēia ʻanohiki i ka hoʻomohala ʻana i nā hale kiʻi ʻike maka houmehoʻonui i ka hoʻonā spatial a me ka hana, nā mea a paume ka ʻoleka pono no ka paʻakikī a me ke kumu kūʻai pixelation kino.
Makemake ʻoe e ʻike hou aku e pili ana i:
Ke kālai ʻia ʻana o ka ʻili uila ma lalo o ka honua?
Nā ʻike no SSLE Scintillation Crystal
1. Hoʻomaikaʻi ʻia ka hua māmā
Hema: Nānā Manaʻo DoI i kālai ʻia i ka Surface Reflectivity Asymmetry.
ʻĀkau: Pixel Displacement DoI.
ʻO ka hoʻohālikelike o nā pulu ma waenanā pūʻulu laser i kālai ʻia i lalo (SSLE).anā papa hana maʻamauhōʻike aʻoi aku ka maikaʻi o ka māmā māmā no SSLE.
ʻO kēia paha ma muli o kaka nele o nā mea hoʻonani plastikma waena o nā pika, hiki ke hoʻohālikelike i ka optical mismatching a me ka poho photon.
ʻO ka hoʻonui ʻia ʻana o ka māmāʻoi aku ka māmā no nā puʻupuʻu ikehu like, e hana ana i ka SSLE i mea makemake.
2. Hoʻonui ʻia ka hana manawa
He Kiʻi o Scintillation Crystal
He ahopena pōʻino i ka manawa, he mea koʻikoʻi ia no nā noi Positron Emission Tomography (PET).
Eia naʻe, ʻo kaʻoi aku ka naʻau o nā kristal SSLEhiki ke hoohana inā kristal pōkole, ka mea hikihoʻomaikaʻi i ka hana manawa o ka ʻōnaehana.
Ua ʻōlelo pū ʻia nā simulation e hiki i nā ʻano pixel like ʻole, e like me hexagonal a dodecagonal pahaalakaʻi i ka alakaʻi māmā a me ka hana manawa, e like me nā loina o nā fiber optical.
3. Pono ke kumu kūʻai
He Kiʻi o Scintillator Crystal
Ke hoʻohālikelike ʻia i nā poloka monolithic, ke kumukūʻai o nā kristal SSLEhiki e like me ka haahaahoʻokahi hapakoluo ke kumukuaio ka huina pixelated e pili ana, ma muli o ka nui o ka pixel.
Eia hou, kaʻoi aku ka naʻau o nā kristal SSLEhiki noka hoʻohana ʻana i nā kristal pōkole, e hoemi hou ana i ke kumukuai holookoa.
Pono ka ʻenehana SSLE i ka mana laser haʻahaʻa i hoʻohālikelike ʻia me ka ʻoki ʻana i ka laser, ʻaenā ʻōnaehana SSLE liʻiliʻihoʻohālikelike ʻia me ka hoʻoheheʻe ʻana i ka laser a i ʻole nā mea ʻoki.
ʻO kahoʻokomo mua i ka ʻoihana a me ke aʻo ʻanano ka mea, he haʻahaʻa loa ka SSLEma mua o ke kumukūʻai o ka hoʻomohala ʻana i kahi mea ʻike PET.
4. Hoʻolālā hoʻololi a me ka hoʻopilikino
ʻO ke kaʻina o ke kahakaha ʻana i nā kristal SSLEʻaʻole hoʻopau manawa, me kahi kokoke15 minukepono e kaha i ka 12.8x12.8x12 mm, 3-crystal array.
ʻO kaʻano maʻalahi, kumu kūʻai, amaʻalahi o ka hoʻomākaukau ʻana i nā kristal SSLE, me ko lakouhakina paʻi kiʻekiʻe, uku no kahaʻahaʻa haʻahaʻa haʻahaʻai hoʻohālikelike ʻia me nā ʻāpana pixelated maʻamau.
Nā Geometry Pixel Kuʻuna ʻole
Hiki iā SSLE ke ʻimi i nānā geometries pixel maʻamau, hiki i ka scintillating pixels ke lilopili pono i nā koi kūikawā o kēlā me kēia noi, e like me nā collimators a i ʻole nā ana o nā kiʻi hoʻonui kiʻi silika.
Kaʻana Māmā Māmā
Hiki ke hoʻokō ʻia ka māhele māmā ʻana ma o ka hoʻoponopono pololei ʻana i nā hiʻohiʻona optical o nā ʻili i kālai ʻia,hoʻomaʻamaʻa hou i ka miniaturization o nā mea ʻike gamma.
Nā Hoʻolālā Kūʻē
Nā hoʻolālā exotic, e like me Voronoi tessellations, hiki kemaʻalahi i kālai ʻia i loko o nā kristal monolithic. Eia kekahi, hiki i ka hoʻohele like ʻole o nā nui pixel ke hiki ke hoʻokomo i nā ʻenehana sensing compressed, me ka hoʻohana ʻana i ka māhele māmā ākea.
Nā Mīkini no ke kahakaha ʻana i lalo o ka honua
Aia ka puʻuwai o Subsurface Laser i ka mīkini kalai laser. Hoʻohana kēia mau mīkinihe laser ʻōmaʻomaʻo kiʻekiʻe, i hoʻolālā ʻia nokalai laser ma lalo o ka honua i loko o ke aniani.
