Zombini intraoral kunye panoramicoomatshini beX-reyibabe nolu lawulo lulandelayo lwe-exposure factor: i-milliamps (mA), ii-kilovolts (kVp), kunye nexesha.Umahluko omkhulu phakathi koomatshini ababini kulawulo lweeparamitha zokuvezwa.Ngokuqhelekileyo, izixhobo ze-X-reyi ze-intraoral zihlala zine-mA kunye nolawulo lwe-kVp olusisigxina, ngelixa ukuvezwa kuyahluka ngokuhlengahlengisa ixesha loqikelelo oluthile lwe-intraoral.Ukuvezwa kweyunithi ye-X-ray yepanoramic ilawulwa ngokulungelelanisa iiparamitha ezincedisayo;ixesha lokuvezwa lilungisiwe, ngelixa i-kVp kunye ne-mA zihlengahlengiswa ngokobungakanani besigulane, ukuphakama, kunye nokuxinana kwamathambo.Ngelixa umgaqo wokusebenza ufana, ifomathi yepaneli yolawulo lokuvezwa inzima kakhulu.
IMilliampere (mA) Ulawulo – Ilawula unikezelo lwamandla ombane ophantsi ngokulungelelanisa ubungakanani bee-electron eziqukuqelayo kwisekethe.Ukutshintsha i-mA setting ichaphazela inani lee-X-reyi eziveliswayo kunye noxinaniso lomfanekiso okanye ubumnyama.Ukutshintsha ngokuphawulekayo ukuxinana komfanekiso kufuna umahluko we-20%.
Ulawulo lweKilovolt (kVp) – Ilawula iisekethe zamandla ombane aphezulu ngokulungelelanisa umahluko onokubakho phakathi kwee-electrode.Ukutshintsha isethingi ye-kV kunokuchaphazela umgangatho okanye ukungena kwee-X-rays eziveliswayo kunye nokwahlukana kwemifanekiso okanye ukuxinana.Ukutshintsha kakhulu ubuninzi bomfanekiso, umahluko we-5% uyafuneka.
Ulawulo lwexesha - Ulawula ixesha apho ii-electron zikhutshwa kwi-cathode.Ukutshintsha ukusetwa kwexesha kuchaphazela inani le-X-reyi kunye noxinaniso lomfanekiso okanye ubumnyama kwi-radiography ye-intraoral.Ixesha lokuvezwa kwi-imaging ye-panoramic lilungiselelwe iyunithi ethile, kwaye ubude bexesha lonke lokuvezwa liphakathi kwe-16 kunye ne-20 imizuzwana.
Ulawulo oluzenzekelayo lokuSebenza (AEC) luphawu lwepanoramaoomatshini beX-reyielinganisa ubungakanani bemitha yemitha efikelela kumamkeli womfanekiso kwaye inqande ukusetwa kwangaphambili xa umamkeli efumana ubushushu obufunekayo bemitha ukuvelisa ukutyhileka komfanekiso okwamkelekileyo.I-AEC isetyenziselwa ukulungelelanisa ubungakanani bemitha ehanjiswa kwisigulane kunye nokwandisa ukuchasana komfanekiso kunye nobuninzi.
