Kodi anode yozungulira ndi chiyani? Funso ili nthawi zambiri limabwera pokambirana zaukadaulo wa machubu a X-ray. M'nkhaniyi, tifufuza mozama za lingaliro lamachubu a X-ray ozungulira anodendi kufufuza tanthauzo lake mu kujambula zithunzi zachipatala.
Kujambula zithunzi za X-ray kwasintha kwambiri ntchito ya zamankhwala mwa kulola madokotala kuona kapangidwe ka mkati mwa thupi popanda kuchita opaleshoni yowononga. Machubu a X-ray ndi ofunika kwambiri pa ukadaulo ndipo amapanga ma X-ray amphamvu kwambiri ofunikira pa njira yojambula zithunzi yosawononga. Anode yozungulira ndi gawo lofunika kwambiri la machubu a X-ray awa, zomwe zimawonjezera mphamvu zawo komanso moyo wawo wautali.
Ndiye, kodi anode yozungulira ndi chiyani kwenikweni? Mwachidule, ndi cholinga chooneka ngati diski chopangidwa ndi zinthu zambiri za atomiki monga tungsten kapena molybdenum. Cholingacho chimazungulira mofulumira panthawi yopanga X-ray, zomwe zimathandiza kuti kutentha kutayike bwino komanso kuti X-ray ituluke kwambiri.
Cholinga chachikulu cha ma anode ozungulira ndikuthana ndi zofooka za ma anode okhazikika. Mu machubu a X-ray okhazikika, kutentha komwe kumachitika panthawi yopanga X-ray kumakhala kochepa pa anode. Kutentha kowonjezereka kumeneku kumawononga anode mwachangu, kuchepetsa mphamvu ndi nthawi yotulutsa X-ray. Ma anode ozungulira amathetsa vutoli pofalitsa kutentha pamalo akuluakulu, motero amachepetsa kuwonongeka kwa anode ndikuwonjezera moyo wa chubu.
Kapangidwe ka ma anode ozungulira kamakhala ndi uinjiniya wovuta. Anode nthawi zambiri imapangidwa ndi tungsten chifukwa imakhala ndi malo osungunuka kwambiri ndipo imatha kupirira kutentha kwakukulu komwe kumapangidwa pamene ma X-ray akupangidwa. Kuphatikiza apo, anode imakutidwa ndi zinthu zopyapyala zotsutsa, monga graphite kapena molybdenum, kuti iwonjezere kutentha kwake.
Kuzungulira kwa anode kumachitika pogwiritsa ntchito rotor ndi ma bearing. Rotor yoyendetsedwa ndi mota yamagetsi imazungulira anode pa liwiro lalikulu, nthawi zambiri pafupifupi ma revolutions 3,000 mpaka 10,000 pamphindi. Ma bearing amatsimikizira kuzungulira kosalala komanso kokhazikika, kusalinganika kulikonse kapena kugwedezeka kungawononge khalidwe la chithunzi.
Ubwino wa machubu a X-ray ozungulira anode ndi ambiri. Choyamba, anode yozungulira ili ndi malo akuluakulu omwe amatha kuyeretsa kutentha bwino, motero nthawi yowonekera imawonjezeka ndikuwonjezera kutulutsa kwa X-ray. Izi zikutanthauza nthawi yochepa yoyezetsa komanso chitonthozo chachikulu cha wodwala. Kuphatikiza apo, kulimba kwa anode yozungulira kumalola chubu cha X-ray kupirira kugwiritsidwa ntchito mobwerezabwereza komanso kwa nthawi yayitali, zomwe zimapangitsa kuti ikhale yoyenera kuzipatala zambiri.
Kuphatikiza apo, kuthekera koyang'ana kuwala kwa X-ray pamalo ang'onoang'ono a anode kumawonjezera kumveka bwino kwa zithunzi zomwe zatuluka. Izi ndizofunikira kwambiri pakujambula zithunzi, komwe kuwona bwino kapangidwe ka thupi ndikofunikira. Kuthekera kowonjezera kutentha kwa anode yozungulira kumathandiza kujambula kosalekeza popanda kusokoneza kuziziritsa, zomwe zimapangitsa kuti ntchito igwire bwino ntchito.
Powombetsa mkota,machubu a X-ray ozungulira anode yasintha kwambiri gawo la kujambula zithunzi zachipatala. Chifukwa cha uinjiniya wawo wapamwamba komanso mphamvu zake zabwino zochotsera kutentha, machubu awa amapereka zabwino zambiri kuposa machubu achikhalidwe okhazikika a anode. Kuyambira kuwonjezeka kwa kutulutsa kwa X-ray ndi moyo wautali wa machubu mpaka kukongola kwa chithunzi, machubu a X-ray ozungulira anode akhala chida chofunikira kwambiri pazachipatala chamakono.
