Kokubili i-intraoral ne-panoramicImishini ye-X-rayibe nalezi zilawuli zesici sokuchayeka ezilandelayo: ama-milliamps (mA), ama-kilovolts (kVp), nesikhathi.Umehluko omkhulu phakathi kwemishini emibili ukulawula imingcele yokuchayeka.Ngokuvamile, amadivaysi e-X-ray e-intraoral ngokuvamile anezilawuli ezigxilile ze-mA ne-kVp, kuyilapho ukuchayeka kuyahlukahluka ngokulungisa isikhathi sokuqagela kwe-intraoral ethile.Ukuvezwa kweyunithi ye-X-ray ye-panoramic kulawulwa ngokulungisa amapharamitha ahambisanayo;isikhathi sokuchayeka sinqunyiwe, kuyilapho i-kVp ne-mA zilungiswa ngokuya ngosayizi wesiguli, ubude, kanye nokuminyana kwamathambo.Nakuba isimiso sokusebenza sifana, ifomethi yephaneli yokulawula ukuchayeka iyinkimbinkimbi kakhulu.
I-Milliampere (mA) Control – Ilawula ukunikezwa kwamandla kagesi aphansi ngokulungisa inani lama-electron agelezayo kusekethe.Ukushintsha ukulungiselelwa kwe-mA kuthinta inani lama-X-reyi akhiqizwayo kanye nokuminyana kwesithombe noma ubumnyama.Ukushintsha ngokuphawulekayo ukuminyana kwesithombe kudinga umehluko ongu-20%.
I-Kilovolt (kVp) Control – Ilawula amasekhethi kagesi aphezulu ngokulungisa umehluko ongaba khona phakathi kwama-electrode.Ukushintsha isethingi ye-kV kungase kuthinte ikhwalithi noma ukungena kwama-X-reyi akhiqizwayo kanye nomehluko ekuhlukeni kwesithombe noma ukuminyana.Ukushintsha kakhulu ukuminyana kwesithombe, umehluko ongu-5% uyadingeka.
Ukulawula Isikhathi - Kulawula isikhathi lapho ama-electron akhululwa ku-cathode.Ukushintsha isilungiselelo sesikhathi kuthinta inombolo ye-X ray kanye nokuminyana kwesithombe noma ubumnyama ku-intraoral radiography.Isikhathi sokuchayeka emfanekisweni we-panoramic simiselwe iyunithi ethile, futhi ubude baso sonke isikhathi sokuchayeka buphakathi kwamasekhondi ayi-16 kuya kwangu-20.
I-Automatic Exposure Control (AEC) isici se-panoramic ethileImishini ye-X-rayekala inani lemisebe efinyelela kumamukeli wesithombe futhi inqamule ukusetha ngaphambilini lapho umamukeli ethola amandla emisebe adingekayo ukuze akhiqize ukuchayeka kwesithombe sokuxilonga okwamukelekayo.I-AEC isetshenziselwa ukulungisa inani lemisebe elethwa esigulini kanye nokuthuthukisa ukugqama kwesithombe nokuminyana.
