Li-tubes tsa X-ray tsa cathode tse potolohang (Rotating Anode X-Ray Tubes) ke mohloli oa X-ray o nepahetseng haholo bakeng sa litšoantšo tsa bongaka le tsa indasteri.Joalokaha lebitso la eona le bontša, e na le cathode e potolohang 'me ke e' ngoe ea likarolo tsa bohlokoa tsa thepa ea X-ray.
Leqhubu la X-ray la cathode le potolohang le na le cathode, anode, rotor le stator.Cathode ke molamu oa tšepe o hlahisang li-electrone thermoelectrically, 'me anode e khahlanong le eona' me e potoloha ho e potoloha.Anode e entsoe ka thepa e phahameng ea mocheso oa mocheso 'me e na le likanale tsa metsi bakeng sa ho pholisa.Hangata anode e entsoe ka tšepe e refractory e kang tungsten, molybdenum, kapa platinum, e hanyetsanang le mocheso le tšenyo ea mahlaseli a mahlaseli a matla a X-rays.
Ha sefate sa elektronike se otla holim'a cathode, lielektrone lia futhumala ebe lia lokolloa.Li-electrone tsena li potlakisa ho ea ho anode, moo li fokotsehang le ho hasana, li hlahisa mahlaseli a X-ray a matla haholo.Anode e potolohang e arolelana mocheso o hlahisitsoeng sebakeng sohle sa anode, 'me e o pholisa ka mocha oa metsi ho netefatsa botsitso le botšepehi ba tšebeliso ea nako e telele.
Li-tubes tse potolohang tsa X-ray tsa cathode li na le melemo e mengata, ho kenyelletsa matla a phahameng, mahlaseli a X-ray a matla haholo, hona joale ho tsepamisitse maikutlo holimo, tekanyo e phahameng ea pontšo-ho lerata, bokhoni ba ho ikamahanya le litlhoko tse fapaneng tsa litšoantšo, le bophelo bo bolelele ba tšebeletso.Ka hona, ke mohloli oa khetho ea X-ray mafapheng a kang litšoantšo tsa bongaka, ho lemoha liphoso tsa CT tsa indasteri, le tlhahlobo e sa senyeheng.
Ka kakaretso, tube ea X-ray ea cathode e potolohang ke mohloli o matla, o tsitsitseng le o ka tšeptjoang oa X-ray o fanang ka litšoantšo tsa X-ray tse nepahetseng, tsa boleng bo phahameng le tse phahameng bakeng sa mefuta e mengata e fapaneng ea likopo tsa litšoantšo.
