Machubu a X-Ray a Anode Ozungulira

Machubu a X-ray ozungulira (Rotating Anode X-Ray Tubes) ndi gwero la X-ray lolondola kwambiri la kujambula zithunzi zachipatala ndi mafakitale. Monga momwe dzina lake likusonyezera, lili ndi cathode yozungulira ndipo ndi chimodzi mwa zinthu zofunika kwambiri pa zida za X-ray.

Chubu cha X-ray chozungulira cha cathode chimakhala ndi cathode, anode, rotor ndi stator. Cathode ndi ndodo yachitsulo yomwe imatulutsa ma elekitironi mothandizidwa ndi thermoelectric, ndipo anode ili moyang'anizana nayo ndipo imazungulira mozungulira. Anode imapangidwa ndi zinthu zotenthetsera kutentha kwambiri ndipo ili ndi njira zamadzi zoziziritsira. Anode nthawi zambiri imapangidwa ndi chitsulo chosasunthika monga tungsten, molybdenum, kapena platinamu, chomwe chimalimbana ndi kutentha ndi kuwonongeka kwa ma radiation kuchokera ku ma X-ray amphamvu kwambiri.

Pamene kuwala kwa ma elekitironi kukafika pamwamba pa cathode, ma elekitironiwo amatenthedwa ndi kutulutsidwa. Ma elekitironi amenewa amafulumizitsidwa kupita ku anode, komwe amachepetsedwa mphamvu ndi kufalikira, zomwe zimapangitsa kuti X-ray ikhale yowala kwambiri. Anode yozungulira imagawa mofanana kutentha komwe kumapangidwa pamwamba pa anode yonse, ndikuziziritsa kudzera mu ngalande yamadzi kuti zitsimikizire kuti kugwiritsidwa ntchito kwa nthawi yayitali kuli kokhazikika komanso kodalirika.

Machubu a X-ray ozungulira a cathode ali ndi zabwino zambiri, kuphatikizapo mphamvu yayikulu, kuwala kwa X-ray kwamphamvu kwambiri, mphamvu yayikulu yowunikira, chiŵerengero chapamwamba cha chizindikiro-ku-phokoso, kuthekera kosintha malinga ndi zofunikira zosiyanasiyana zojambula, komanso moyo wautali wautumiki. Chifukwa chake, ndi gwero losankhidwa la X-ray m'magawo monga kujambula zamankhwala, kuzindikira zolakwika za CT zamafakitale, komanso kuyesa kosawononga.

Mwachidule, chubu chozungulira cha cathode X-ray ndi gwero lamphamvu kwambiri, lokhazikika komanso lodalirika la X-ray lomwe limapereka zithunzi zolondola, zapamwamba komanso zapamwamba za X-ray zamitundu yosiyanasiyana ya zithunzi.
