Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso chitukuko chaukadaulo wazachipatala, mwayi woti anthu azitha kujambulidwa ndi X-ray akapita kuchipatala nawonso wakula kwambiri.Aliyense amadziwa kuti chifuwa X-ray, CT, mtundu ultrasound ndi X-ray makina akhoza kutulutsa X-ray kulowa thupi la munthu kuona matenda.Amadziwanso kuti ma X-ray amatulutsa ma radiation, koma ndi anthu angati omwe amamvetsetsa makina a X-ray.Nanga bwanji cheza chotuluka?
Choyamba, ma X-rays amapangidwa bwanjiX-ray makinakupangidwa?Zomwe zimafunikira kuti pakhale ma X-ray omwe amagwiritsidwa ntchito pachipatala ndi awa: 1. X-ray chubu: chubu lagalasi la vacuum lomwe lili ndi maelekitirodi awiri, cathode ndi anode;2. Mbale ya Tungsten: Tungsten yachitsulo yokhala ndi nambala yayikulu ya atomiki ingagwiritsidwe ntchito kupanga machubu a X-ray Anode ndiye chandamale cholandirira bomba la ma elekitironi;3. Ma electron akuyenda mothamanga kwambiri: gwiritsani ntchito magetsi okwera kumapeto onse a X-ray chubu kuti ma electron aziyenda mofulumira.Ma transfoma apadera amakweza mphamvu yamagetsi kuti ikhale yokwera kwambiri.Mbale ya tungsten ikagundidwa ndi ma elekitironi omwe akuyenda mothamanga kwambiri, maatomu a tungsten amatha kulowetsedwa kukhala ma elekitironi kupanga ma X-ray.
Kachiwiri, X-ray iyi ndi yotani, ndipo chifukwa chiyani ingagwiritsidwe ntchito kuyang'ana momwe zilili pambuyo polowa m'thupi la munthu?Izi ndichifukwa cha mawonekedwe a X-ray, omwe ali ndi zinthu zitatu zazikulu:
1. Kulowa: Kulowera kumatanthauza kuthekera kwa X-ray kudutsa muzinthu popanda kutengeka.Ma X-ray amatha kuloŵa zinthu zomwe kuwala kwamba sikungathe.Kuwala kowoneka kumakhala ndi utali wautali, ndipo ma photon ali ndi mphamvu zochepa kwambiri.Ikagunda chinthu, mbali yake imawonekera, yambiri imatengedwa ndi chinthu, ndipo sichingadutse chinthucho;pomwe ma X-ray sali, chifukwa cha kutalika kwawo kwaufupi, mphamvu Ikamawala pazinthu, gawo limodzi lokha limatengedwa ndi zinthuzo, ndipo zambiri zimafalikira kudzera mumpata wa atomiki, kuwonetsa mphamvu yolowera mwamphamvu.Kuthekera kwa ma X-ray kulowa m'zinthu kumagwirizana ndi mphamvu ya X-ray photon.Kufupikitsa kwa kutalika kwa mafunde a X-ray, mphamvu ya ma photon imachulukirachulukira komanso mphamvu yolowera kwambiri.Mphamvu yolowera ya X-ray imagwirizananso ndi kachulukidwe ka zinthuzo.Zinthu zowuma zimatenga ma X-ray ambiri ndikutumiza pang'ono;zinthu zonenepa zimatenga pang'ono ndikufalitsa zambiri.Pogwiritsa ntchito mayamwidwe osiyanitsa, minofu yofewa monga mafupa, minofu, ndi mafuta omwe ali ndi makulidwe osiyanasiyana amatha kusiyanitsa.Ichi ndiye maziko akuthupi a X-ray fluoroscopy ndi kujambula.
2. Ionization: Chinthu chikayatsidwa ndi X-ray, ma elekitironi a extranuclear amachotsedwa munjira ya atomiki.Izi zimatchedwa ionization.Mu ndondomeko ya photoelectric zotsatira ndi kubalalitsidwa, njira imene photoelectrons ndi recoil ma elekitironi amasiyanitsidwa ndi maatomu awo amatchedwa pulayimale ionization.Ma electron awa kapena ma electron amawombana ndi ma atomu ena pamene akuyenda, kotero kuti ma elekitironi ochokera ku ma atomu ogunda amatchedwa ionization yachiwiri.mu zolimba ndi zamadzimadzi.The ionized zabwino ndi zoipa ions adzalumikizana mwamsanga ndipo si zophweka kusonkhanitsa.Komabe, mtengo wa ionized mu mpweya ndi wosavuta kusonkhanitsa, ndipo kuchuluka kwa ionized charge kungagwiritsidwe ntchito kudziwa kuchuluka kwa X-ray: zida zoyezera X-ray zimapangidwa motengera mfundo iyi.Chifukwa cha ionization, mpweya ukhoza kuyendetsa magetsi;zinthu zina zimatha kukhudzidwa ndi kusintha kwamankhwala;zotsatira zosiyanasiyana zamoyo zitha kupangika mwa zamoyo.Ionization ndiye maziko a kuwonongeka kwa X-ray ndi chithandizo.
3. Fluorescence: Chifukwa cha kutalika kwafupipafupi kwa X-ray, ndi yosaoneka.Komabe, pamene watsitsidwa kuzinthu zina monga phosphorous, platinamu cyanide, zinki cadmium sulfide, calcium tungstate, ndi zina zotero, maatomu amakhala okondwa chifukwa cha ionization kapena chisangalalo, ndipo maatomu amabwerera ku nthaka pansi pa ndondomekoyi. , chifukwa cha kusintha kwa msinkhu wa mphamvu ya ma electron a valence.Imatulutsa kuwala kowoneka kapena ultraviolet, komwe ndi fluorescence.Zotsatira za X-ray zomwe zimapangitsa kuti zinthu ziwonongeke zimatchedwa fluorescence.Kuchuluka kwa fluorescence kumayenderana ndi kuchuluka kwa X-ray.Izi ndi maziko a ntchito X-ray kuti fluoroscopy.Mu ntchito yowunikira ma X-ray, mtundu uwu wa fluorescence ungagwiritsidwe ntchito kupanga chophimba cha fulorosenti, chophimba chowonjezera, chophimba cholowera muzowonjezera chithunzi ndi zina zotero.Chophimba cha fulorosenti chimagwiritsidwa ntchito poyang'ana zithunzi za X-ray zikudutsa mu minofu ya anthu panthawi ya fluoroscopy, ndipo chophimba chowonjezera chimagwiritsidwa ntchito kuti filimuyo ikhale yomveka panthawi yojambula.Zomwe zili pamwambazi ndizofotokozera zambiri za X-ray.
