Nekufambira mberi kwesainzi uye tekinoroji uye nekuvandudzwa kwehunyanzvi hwekurapa, mikana yevanhu iri kuvhenekerwa ne-x-rays kana vachienda kuchipatara vakawedzerawo. Wese munhu anoziva kuti chipfuva X-rays, ct, ruvara ruzha uye x-ray michina inogona kuburitsa x-rays yekupinda mumuviri wemunhu kuti uchengete chirwere ichi. Vanozivawo kuti X-RAYS EMAR Radiation, asi vangani vanhu vanonyatsonzwisisa X-ray michina. Zvakadiniko nezvezvakabuda marara?
Kutanga, sei x-rays muneX-Ray MachineYakagadzirwa? Mamiriro acho anodiwa pakugadzirwa kwe x-rays anoshandiswa mumushonga ari seinotevera: 1 2. 3 Inyanzvi yekushandura inoshandura inokwirisa voltage mupenyu kune iyo inodiwa kwazvo voltage. Mushure mekunge tungsten ndiro iri kurohwa nemagetsi zvinofamba nekumhanya kwakanyanya, maatomu e tungsten anogona ionised mune electrons kuumba X-rays.
Kechipiri, chii chimiro cheiyi x-ray, uye nei zvichigona kushandiswa kucherechedza mamiriro acho mushure mekupinda mumuviri wemunhu? Izvi zvese zvese nekuda kwezvivakwa zve x-ray, ayo ane matatu makuru epamhepo:
1. PENTERATION: PENETRINE inoreva kugona kweiyo X-rays kuti ipfuure kuburikidza nechinhu pasina kunyudzwa. X-rays dzinogona kupinza zvinhu zvinowanzoitika mwenje unooneka haugone. Chiedza chinooneka chine refu wavelength, uye mafoto ane simba shoma kwazvo. Kana ichirova chinhu, chikamu chayo chinoratidzwa, yakawanda yacho inodhonzwa nezvinhu, uye haigoni kupfuura nechinhu; Nepo X-Rays isiri, nekuda kweiyo pfupi yekucheka, simba parinopenya pane izvo zvinyorwa, chikamu chakabatanidzwa nezvinhu, uye zvakawanda zvacho zvinotapurirana neatomu, zvichiratidza kugona kwakasimba. Iko kugona kwe x-rays yekupinza nyaya ine chekuita nesimba re x-ray mafoto. Iyo ipfupi iyo wavelength ye x-rays, iyo yakakura simba remapikicha uye yakasimba simba rinopinda. Simba rinopinza re x-ray rine hukama nehuremu hwezvinyorwa. Iyo denser yezvinhu inotora yakawanda x-rays uye inoburitsa zvishoma; Iyo denser yezvinhu inotora zvishoma uye inoburitsa zvimwe. Uchishandisa nzvimbo iyi yekunyoroveswa kusiyanisa, matishu akapfava senge mapfupa, mhasuru, uye mafuta ane densiti dzakasiyana dzinogona kusiyaniswa. Iyi ndiyo nheyo yemuviri ye x-ray fluoroscopy uye kutora mifananidzo.
2. Ionization: Kana chinhu chacho chakatsikwa ne x-rays, iyo magetsi emagetsi emagetsi anobviswa kubva paatomic orb. Maitiro aya anonzi ionization. Mukuita kweThepertictric mhedzisiro uye kupaza, maitiro ayo mafanelelectrons emahara uye exial Electrons ari kupatsanurwa kubva kumaatomu avo anonzi Prinary ionization ionization ionization. Aya mafoto emota kana kudzokorora Electrons anofambidzana nemamwe maatomu achifamba, zvekuti maairau emagetsi anobva maatomu akanzi wechipiri wonization ionization. mune solids uye zvinwiwa. Iyo ionized yakanaka uye isina kunaka ion ichatsiva nekukurumidza uye haisi nyore kuunganidza. Nekudaro, iyo yakashongedzwa mutero mugesi iri nyore kuunganidza, uye huwandu hweionized kubhadharisa kunogona kushandiswa kuona huwandu hweX-ray kuratidzwa: zviridzwa zveXy-ray zvinogadzirwa zvichienderana neiyi nheyo. Nekuda kweionization, magasi anogona kuitisa magetsi; zvimwe zvinhu zvinogona kuitika kumakemikari maitiro; Mhedzisiro dzakasiyana siyana dzinogona kukonzerwa nezvisikwa. Ionization ndiyo hwaro hwe x-ray kukuvara uye kurapwa.
3. Fluorescence: Nekuda kweiyo pfupi wavelength ye x-rays, hazvionekwe. Nekudaro, kana zvadzingwa kune dzimwe mishonga yakadai senge phosphorus, platin cyanide, calcium tungstate, etchcuum turment Iyo inoburitsa pachena kana kuti Ultravioler mwenje, iyo iri fluorescence. Mhedzisiro ye x-rays inokonzeresa zvinhu kuFluoleryce inonzi fluorescence. Kukura kweFluorescence kwakaunganidzwa kune huwandu hwe x-rays. Iyi mhedzisiro ndiyo hwaro hwekushandisa kwe x-rangi kune fluoroscopy. MuX-Ray Daagnostic basa, urwu rudzi rweferescence inogona kushandiswa kugadzira fluorescent skrini, kuwedzera skrini, yekuisa screen mune inopisa uye zvichingodaro. Iyo fluorescent skrini inoshandiswa kucherechedza mifananidzo ye x-rays ichipfuura nemumato emunhu panguva yeFluoroscopy, uye iyo skrini yekuwedzera inoshandiswa kusimudzira kunzwa kweiyo firimu panguva yekutora mifananidzo. Iyo iri pamusoro ndeye general sumo kune x-rays.
Isu tinoiftang newheek Electronic tekinoroji co., Ltd. Mugadziri anogadzira nyanzvi mukugadzirwa uye kutengesa kweX-Ray michina. Kana iwe uine chero mibvunzo nezve ichi chigadzirwa, unogona kubata nesu. Tel: +8617616362243!
