Imishini ye-X-rayhave the following exposure factor controls: milliamps (mA), kilovolts (kVp), and time. Umehluko omkhulu phakathi kwale mishini emibili ukuphathwa kwamapharamitha wokuvezwa. Imvamisa, amadivayisi we-Intraoural x-ray ngokuvamile anezilawuli ze-MA ne-KVP, ngenkathi ukuvezwa kuhlukahluka ngokulungisa isikhathi sokuqagelwa okuqondile kwe-Intraouse. The exposure of the panoramic X-ray unit is controlled by adjusting complementary parameters; the exposure time is fixed, while the kVp and mA are adjusted according to the patient's size, height, and bone density. While the principle of operation is the same, the format of the exposure control panel is more complex.
Imishini ye-X-rayLokho kukala inani lemisebe lifinyelela isitholi sesithombe futhi liphelelwa isethathi lapho owemukelayo ethola ukuvezwa kwemisebe edingekayo ukukhiqiza ukuvezwa kwezithombe okwamukelekayo. AEC is used to adjust the amount of radiation delivered to the patient and to optimize image contrast and density.
