Kuzindikira zodetsa ndiye njira yoyamba yowunikira ma X-ray popanga zakudya ndi mankhwala, ndipo ndikofunikira kuwonetsetsa kuti zoyipitsidwa zonse zimachotsedwa mosasamala kanthu za kagwiritsidwe ntchito ndi mtundu wake kuti zitsimikizire chitetezo cha chakudya.
Machitidwe a X-ray amakono ndi apadera kwambiri, ogwira ntchito komanso otsogola, ndipo amagwiritsidwa ntchito m'mafakitale osiyanasiyana kuti awonedwe, kuphatikizapo kufufuza zachipatala, kufufuza zakudya ndi mankhwala, zomangamanga (zomangamanga, migodi ndi zomangamanga), ndi chitetezo. M'munda wachitetezo, amagwiritsidwa ntchito "kuwona" mkati mwa katundu kapena phukusi. Opanga zakudya ndi mankhwala amadaliranso makina a X-ray kuti azindikire ndi kuchotsa zinthu zowonongeka kuchokera ku mizere yopanga kuti ateteze ogula, kuchepetsa chiopsezo cha kukumbukira mankhwala ndi kusunga malonda awo.
Koma makina a X-ray amazindikira bwanji zowononga? Nkhaniyi ikufotokoza zomwe X-rays ndi momwe makina oyendera ma X-ray amagwirira ntchito.
1. Kodi ma X-ray ndi chiyani?
Ma X-ray ndi amodzi mwa ma radiation angapo omwe amapezeka mwachilengedwe ndipo ndi mawonekedwe osawoneka a ma radiation a electromagnetic, monga mafunde a wailesi. Mitundu yonse ya ma radiation a electromagnetic ndi njira imodzi yokha yopitilira mu mawonekedwe a electromagnetic, yokonzedwa molingana ndi ma frequency ndi kutalika kwa mafunde. Imayamba ndi mafunde a wailesi (utali wavelength) ndipo imathera ndi kuwala kwa gamma (ufupi wavelength). Kutalika kwaufupi kwa X-ray kumawalola kulowa m'zinthu zomwe zimakhala zosawoneka bwino mpaka kuwala kowoneka bwino, koma sizimalola m'zinthu zonse. Kutumiza kwa chinthu kumagwirizana kwambiri ndi kachulukidwe kake - kuchulukira komwe kuli, ma X-ray ochepa omwe amatumiza. Zoyipa zobisika, kuphatikiza magalasi, mafupa owerengetsera ndi chitsulo, zimawonekera chifukwa zimayamwa ma X-ray ambiri kuposa mankhwala ozungulira.
2. Mfundo Zoyendera X-ray Mfundo zazikuluzikulu
Mwachidule, makina a X-ray amagwiritsa ntchito jenereta ya X-ray kuti apangire mtengo wochepa wa mphamvu ya X-ray pa sensa kapena detector. Chogulitsa kapena phukusi limadutsa pamtengo wa X-ray ndikufika pa chowunikira. Kuchuluka kwa mphamvu za X-ray zomwe zimatengedwa ndi chinthucho zimagwirizana ndi makulidwe, kachulukidwe ndi nambala ya atomiki ya chinthucho. Pamene mankhwalawa akudutsa pamtengo wa X-ray, mphamvu yotsalira yokha imafika pa chowunikira. Kuyeza kusiyana kwa kuyamwa pakati pa chinthucho ndi choyipitsidwa ndi maziko ozindikira thupi lakunja pakuwunika kwa X-ray.
