Muminda yekufungidzira kwekurapa uye kuongororwa, tekinoroji yeX-ray yakaita basa rakakosha kwemakumi emakore. Pakati pezvinhu zvakasiyana-siyana zvinogadzira X-ray muchina, iyo inotemerwa anode X-ray chubhu yava chinhu chakakosha chemidziyo. Aya machubhu haangopi radiation inodiwa pakufungidzira, asi zvakare inoona kunaka uye kugona kweiyo X-ray system yese. Mune ino blog, isu tichaongorora mafambiro mune yakagadziriswa anode X-ray machubhu uye kuti kufambira mberi kwetekinoroji kuri kushandura sei chikamu chakakosha ichi.
Kubva pakutanga kusvika pakuzvarwa kwemazuva ano:
Stationary anode X-ray machubhuvane nhoroondo refu kubva pakatanga kuwanikwa maX-rays naWilhelm Conrad Roentgen mukutanga kwezana ramakore rechi20. Pakutanga, machubhu aive akareruka girazi akavharirwa inogara iyo cathode uye anode. Nekuda kwekunyungudika kwayo kwakakwira, anode inowanzogadzirwa ne tungsten, iyo inogona kuoneswa kuyerera kwema electrons kwenguva yakareba pasina kukuvara.
Nekufamba kwenguva, sezvo kudiwa kwekufungidzira kwakanyanya uye kwakaringana kwakakura, kufambira mberi kukuru kwakaitwa mukugadzira nekuvaka kwemachubhu anode X-ray akamira. Kuunzwa kwemachubhu anotenderedza anode uye kugadzirwa kwezvinhu zvakasimba zvinobvumira kuwedzera kupisa kwekupisa uye kubuda kwesimba repamusoro. Nekudaro, iyo mutengo uye kuomarara kwekutenderera anode machubhu kwakaganhurira kutorwa kwavo kwakapararira, zvichiita kuti stationary anode tubes ive sarudzo huru yekufungidzira kwekurapa.
Zvichangoburwa maitiro mune yakagadziriswa anode X-ray machubhu:
Munguva pfupi yapfuura, zvakakosha kuvandudzwa kwetekinoroji zvakakonzera kutangazve mukuzivikanwa kweiyo fixed-anode X-ray machubhu. Kufambira mberi uku kunogonesa hunyanzvi hwekufungidzira, simba repamusoro, uye hukuru hwekupisa kupisa, zvichiita kuti dzive dzakavimbika uye dzishande kupfuura nakare kose.
Chiratidzo chinocherechedzwa ndechekushandiswa kwesimbi dzinoramba dzakadai se molybdenum uye tungsten-rhenium alloys seanode zvinhu. Masimbi aya ane hunyanzvi hwekupisa kupisa, achibvumira machubhu kuti akwanise kumirisana nemazinga emagetsi epamusoro uye nguva refu yekuratidzwa. Iyi budiriro yakabatsira zvikuru mukuvandudzwa kwemhando yemifananidzo uye kuderedzwa kwekufungidzira nguva muchirongwa chekuongorora.
Pamusoro pezvo, imwe nzira yekutonhora yekudziya yakaunzwa kuti iverenge kupisa kunoitwa panguva yeX-ray emission. Nekuwedzerwa kwesimbi yemvura kana yakanyatsogadzirirwa anode holders, kupisa kwekupisa kweiyo yakagadziriswa anode tubes kunowedzerwa zvakanyanya, kuderedza njodzi yekupisa uye kuwedzera hupenyu hwese hwemachubhu.
Imwe nzira inonakidza ndeyekubatanidzwa kweazvino matekinoroji ekufungidzira akadai sedhijitari madhijitari uye mifananidzo yekugadzirisa algorithms ine yakagadziriswa anode X-ray machubhu. Kubatanidzwa uku kunobvumira kushandiswa kwemhando yepamusoro yekutora mifananidzo yakadai sedhijitari tomosynthesis uye cone beam computed tomography (CBCT), zvichiita kuti pave nekuwedzera kwakaringana 3D kuvakazve uye kuvandudzwa kwekuongorora.
mukupedzisa:
Mukupedzisa, maitiro akanangastationary anode X-ray tubes iri kuramba ichishanduka kuti ienderane nezvinodiwa zvemazuva ano ekurapa mifananidzo. Kufambira mberi kwezvinhu, nzira dzekutonhodza, uye kubatanidzwa kweanocheka-kumucheto ekufungidzira matekinoroji akashandura ichi chakakosha chikamu cheX-ray masisitimu. Nekuda kweizvozvo, vashandi vehutano vanogona ikozvino kupa varwere mufananidzo uri nani, kushomeka kwemwaranzi uye ruzivo rwakanyanya rwekuongorora. Zviri pachena kuti yakagadziriswa anode X-ray tubes icharamba ichiita basa rinokosha mukufungidzira kwezvokurapa, kutyaira hutsva uye kugovera kuvandudza kutarisirwa kwevarwere.
