Ob leeg intraoral thiab panoramicX-ray tshuabmuaj cov nram qab no raug cov yam ntxwv tswj: milliamps (mA), kilovolts (kVp), thiab lub sij hawm.Qhov sib txawv tseem ceeb ntawm ob lub tshuab yog kev tswj hwm qhov tsis raug.Feem ntau, intraoral X-ray cov cuab yeej feem ntau muaj kev ruaj ntseg mA thiab kVp tswj, thaum muaj qhov sib txawv los ntawm kev kho lub sij hawm ntawm qhov tshwj xeeb intraoral projections.Qhov raug ntawm panoramic X-ray chav tsev yog tswj los ntawm kev kho cov kev tsis sib xws;Lub sij hawm raug raug kho, thaum lub kVp thiab mA raug kho raws li tus neeg mob qhov loj, qhov siab, thiab pob txha ceev.Thaum lub hauv paus ntsiab lus ntawm kev ua haujlwm yog tib yam, cov qauv ntawm kev tiv thaiv kev tiv thaiv raug ntau dua.
Milliampere (mA) Tswj - Tswj cov khoom siv hluav taws xob tsawg-voltage los ntawm kev kho cov khoom siv hluav taws xob uas ntws hauv Circuit Court.Hloov qhov chaw mA cuam tshuam rau cov X-rays tsim thiab cov duab ntom ntom lossis tsaus.Qhov tseem ceeb hloov cov duab ceev yuav tsum muaj 20% sib txawv.
Kilovolt (kVp) Tswj - tswj cov hluav taws xob hluav taws xob siab los ntawm kev kho qhov sib txawv ntawm cov electrodes.Hloov qhov chaw kV tuaj yeem cuam tshuam qhov zoo lossis nkag mus ntawm X-rays tsim thiab qhov sib txawv ntawm cov duab sib piv lossis qhov ntom ntom.Txhawm rau hloov cov duab ntom ntom, qhov sib txawv ntawm 5% yog xav tau.
Lub Sijhawm Tswjhwm - Tswj lub sijhawm uas cov electrons tawm ntawm lub cathode.Hloov lub sijhawm teeb tsa cuam tshuam rau tus naj npawb ntawm X-rays thiab cov duab ntom ntom lossis tsaus ntuj hauv intraoral radiography.Lub sij hawm raug rau hauv cov duab panoramic yog tsau rau ib chav tsev tshwj xeeb, thiab qhov ntev ntawm tag nrho lub sij hawm raug yog nyob nruab nrab ntawm 16 thiab 20 vib nas this.
Automatic Exposure Control (AEC) yog qhov tshwj xeeb ntawm qee qhov panoramicX-ray tshuabuas ntsuas tus nqi hluav taws xob mus txog cov duab receiver thiab txiav tawm ib qho preset thaum tus txais tau txais qhov xav tau hluav taws xob siv hluav taws xob los tsim cov duab pom tau zoo.AEC yog siv los kho tus nqi hluav taws xob xa mus rau tus neeg mob thiab txhawm rau txhim kho cov duab zoo sib xws thiab qhov ntom ntom.
