Radiography ntawm lub ntsws pab kom kawm cov ntsws nrog kev pab X-rays. Cov duab nrov tshaj plaws yog fluorography . Nws muaj cov txheej txheem nyob rau hauv cov txheej txheem ntawm tus txheej txheem, vim tias tus neeg mob tau txais ib koob me ntsis ntawm hluav taws xob, thaum qhov kev kuaj ntawd yog pheej yig. Tsis tas li ntawd, qhov kev tshwm sim ntawm qhov tshwm sim yog li cas, yog li, fluorography muaj nyob rau hauv daim ntawv teev txhua xyoo kev xeem. Tab sis xav txog lwm yam, ntau tshaj qhia, hom mob ntsws X-rays.
Radiography ntawm lub ntsws nrog tsawg koob tshuaj
Thawj hom kab mob ntsws raum tau hu ua low-dose lossis CCD-detector. Nws npo yog them nrog phosphor, yog li pom nws zoo li lub TV hauv lub 80s. Qhov kev nyeem ntawv yog ua siv ib lub laser infrared uas nkoos rau phosphor.
Txij li thaum lub caij no tau tsim ntau tshaj peb caug xyoo dhau los lawm, nws muaj nws cov teeb meem:
- nce nyob rau sijhawm;
- fuzziness thiab artifacts, feem ntau nyob ib ncig ntawm cov duab ntawm cov duab, uas yog vim li cas qhov kev lag luam no tsis tau suav hais tias yog loj heev rau ib lub sij hawm ntev;
- tsis meej daws teeb meem.
Cov kev tsis haum no cuam tshuam rau cov lus nug ntawm qhov kev tshawb fawb, vim nws tsis yog ib txwm ua tau los txheeb xyuas cov kab mob ntawm cov theem pib ntawm kev loj hlob. Tias yog vim li cas lub cuab yeej tau zoo tag nrho, vim li ntawd, ib qho digital apparatus rau X-hluav taws xob ntawm lub ntsws tau tsim.
Cov xov tooj cua ntawm lub ntsws
Lub digital apparatus rau radiography ntawm lub ntsws muaj undeniable zoo, ntawm uas yog ib tug yooj yim version ntawm daim duab, uas excludes kev tsim ntawm daim duab, thaum nws yog khaws cia nyob rau hauv lub computer lub cim xeeb thiab tseem muaj ntev txaus.
Ib qho tseem ceeb ntawm cov cuab yeej niaj hnub tseem ceeb tshaj plaws ntawm daim duab, tsis muaj teeb meem thiab qhov muag plooj, tab txawm nyob ntawm tus ntug. Vim muaj qhov tseeb ntawm txoj kev tshawb fawb, tus kws kho mob tuaj yeem pom cov kev hloov hauv lub ntsws, yog li ntawd qhov kev kho mob yuav tshwm sim ntau dua.
Muaj coob tus ntshai tias cov khoom siv digital irradiates ntau ntau tshaj li nws cov thawj ntawm. Qhov no yog ib qho kev xav tsis sib xws, vim muaj ntau yam khoom siv niaj hnub no tsis tsuas yog tsis pub dhau qib ntawm irradiation, tab sis kuj tau tawm me ntsis ntawm koob tshuaj tawg. Yog li ntawd, hnub no nyiam muab rau cov qauv tshiab ntawm cov tshuab xoo hluav taws xob.
Nyob rau hauv cov ntaub ntawv dab tsi yog ntsuam xyuas mob ntsws?
Kev kuaj xoo hluav taws xob ntawm lub ntsws yog ua rau mob ntsws, xws li:
- tuberculosis ;
- mob ntsws o;
- ntau hom mob ntsws;
- qog;
- cov kev mob ntsws ntawm kev lag luam ntawm ib qho txawv.
Radiography ntawm lub ntsws nrog tus kab mob pneumonia qhia tau tias yog lub ntsej muag qis focal. Yog hais tias muaj kab noj hniav hauv lub ntsws, ces peb tuaj yeem xav tias muaj tuberculosis los yog lub plab ntawm lub qog.
