ʻO ka rotating cathode X-ray tubes (Rotating Anode X-Ray Tubes) he kumu X-ray kiʻekiʻe no ka lāʻau lapaʻau a me ka ʻoihana kiʻi.E like me ka hōʻike ʻana o kona inoa, aia kahi cathode rotating a ʻo ia kekahi o nā mea nui o nā lako X-ray.
ʻO ka pahu pahu X-ray cathode rotating he cathode, he anode, he rotor a me kahi stator.ʻO ka cathode he koʻokoʻo metala e hoʻokuʻu ana i nā electrons thermoelectrically, a ʻo ke anode ke kū'ē iā ia a hoʻololi a puni ia.Hana ʻia ka anode me nā mea hoʻoheheʻe wela kiʻekiʻe a loaʻa nā ala wai no ka hoʻoilo.Hana ʻia ka anode me ka metala refractory e like me ka tungsten, molybdenum, a i ʻole platinum, ka mea kūʻē i ka wela a me ka pōʻino o ka radiation mai nā kukui X-ikaika.
Ke pā ka uila uila i ka ʻili o ka cathode, hoʻomehana ʻia nā electron a hoʻokuʻu ʻia.Hoʻonui ʻia kēia mau electrons i ka anode, kahi e hoʻoemi ʻia ai lākou a hoʻopuehu ʻia, e hana ana i ka radiation X-ray kiʻekiʻe.Hāʻawi like ka anode rotating i ka wela i hana ʻia i ka ʻili anode holoʻokoʻa, a hoʻomaha iā ia ma o ke kahawai wai e hōʻoia i ka paʻa a me ka hilinaʻi o ka hoʻohana lōʻihi.
ʻO ka rotating cathode X-ray tubes he nui nā pono, me ka mana kiʻekiʻe, kiʻekiʻe-intensity X-ray radiation, kiʻekiʻe ka nānā ʻana i kēia manawa, kiʻekiʻe signal-to-noise ratio, hiki ke hoʻololi i nā koi kiʻi like ʻole, a me ke ola lawelawe lōʻihi.No laila, ʻo ia ke kumu X-ray i koho ʻia ma nā kahua e like me ke kiʻi lāʻau lapaʻau, ka ʻike ʻana i ka flaw CT ʻoihana, a me ka hoʻāʻo ʻole luku.
ʻO ka hōʻuluʻulu manaʻo, ʻo kahi pahu X-ray cathode rotating he kumu mana kiʻekiʻe, kūpaʻa a hilinaʻi hoʻi e hāʻawi ana i nā kiʻi X-ray pololei, kiʻekiʻe a me ka hoʻonā kiʻekiʻe no nā ʻano noi kiʻi like ʻole.
