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.

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.

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

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.
