Hauv kev cuam tshuam hluav taws xob (tseem hu ua IR), cov kws kho mob siv cov duab kho mob los coj cov txheej txheem phais mob me me uas kuaj xyuas, kho, thiab kho ntau yam mob. Kev siv cov duab thaij duab suav nrog fluoroscopy, MRI, CT, thiab ultrasound.
Cov txheej txheem dab tsi cuam tshuam txog hluav taws xob ua haujlwm?
Piv txwv ntawm cov kev kho mob uas tswj hwm los ntawm kev cuam tshuam hluav taws xob muaj xws li angioplasty, stenting, thrombolysis, embolization, radiofrequency ablation, thiab biopsies. Cov kev kho mob me me no tuaj yeem kho lossis txo cov tsos mob ntawm cov kab mob vascular, mob stroke, uterine fibroids, lossis mob qog noj ntshav.
Puas kuaj mob hluav taws xob cuam tshuam?
Los ntawm X-rays thiab MRIs mus rau ultrasounds thiab CT scans, kuaj kab mob kis tau kws kho mob tsis muaj kev cuam tshuamsaib seb muaj dab tsi tshwm sim hauv lub cev.
Kev cuam tshuam hluav taws xob yog dab tsi muab piv txwv?
"Interventional Radiology" (IR) yog hais txog ntau yam txuj ci uas tso siab rau kev siv cov duab hluav taws xob qhia (X-ray fluoroscopy, ultrasound, xam tomography [CT] lossis Sib nqus resonance imaging [MRI]) kom meej lub hom phiaj kho.
Puas yog Interventional Radiology txiav txim siab phais?
Tsis zoo li kev phais ib txwm, kev cuam tshuam hluav taws xob xav tau tsuas yog qhov kev txiav me me qhov loj ntawm tus pinhole. Qhov ntawd txhais tau hais tias mob tsawg dua rau cov neeg mob-thiab kev rov qab sai dua. Feem ntau cov txheej txheem cuam tshuam hluav taws xob tuaj yeem ua tauua tiav hauv qhov chaw kho mob sab nraud, tso cai rau ntau tus neeg mob mus tsev tib hnub lawv tau txais kev kho mob.

Hauv cov khoom siv hluav taws xob tsim hluav taws xob?
Nyob hauv cov khoom siv hluav taws xob tsim hluav taws xob, xws li hlau, hluav taws xob rhaub, boiler, toaster thiab lwm yam, ib qho hlau xws li Nichrome Nichrome Nichrome (tseem hu ua NiCr, nickel-chromium lossis chromium-nickel) yog ib tsev neeg ntawm cov alloys ntawm npib tsib xee, chromium, thiab feem ntau hlau (thiab tejzaum nws muaj lwm yam) feem ntau siv raws li cov hlau tsis kam, cov khoom cua sov hauv cov khoom xws li toasters thiab qhov chaw tso cua sov, hauv qee qhov
Puas yog hluav taws xob hluav taws xob muaj ob qhov xwm txheej?
EM hluav taws xob yog lub npe vim nws muaj hluav taws xob thiab sib nqus teb uas ib txhij oscillate hauv cov dav hlau sib koom ua ke rau ib leeg thiab rau kev taw qhia ntawm kev nthuav tawm los ntawm qhov chaw. ✓ Electromagnetic tawg muaj ob qhov xwm txheej:
Puas hluav taws xob hluav taws xob puas tsim hluav taws xob?
Coal feem ntau siv roj los tsim hluav taws xobhauv Tebchaws Meskas. Hauv cov chaw tsim hluav taws xob hluav taws xob hluav taws xob, cov hluav taws xob bituminous, subbituminous thee, lossis lignite raug hlawv. Cov cua kub uas tsim los ntawm kev sib xyaw ntawm cov thee yog siv los hloov cov dej mus rau hauv qhov chaw siab zog, uas tsav lub turbine, uas tsim hluav taws xob.
Cov txheej txheem vuam twg siv cov khoom siv hluav taws xob?
Cov txheej txheem hlau inert gas (MIG)siv cov khoom siv hluav taws xob, uas feem ntau yog nyob rau hauv daim ntawv ntawm tooj liab-coated coiled hlau. Argon yog siv los tiv thaiv cov vuam, thiab ncaj qha tam sim no nrog cov electrode yog qhov zoo los tsim kom muaj cua sov ntau rau melting.
Lub tshuab hluav taws xob hluav taws xob tsim hluav taws xob li cas?
Piav seb lub twj hluav taws xob hluav taws xob tsim hluav taws xob hla lub membrane li cas. Los ntawm pum electrons hla lub membrane, sab uas cov electrons raug tshem tawm muaj qhov zoo dua, thaum sab tau txais cov hluav taws xob ntau muaj qhov tsis zoo.
