Zvese zviri zviviri intraoral uye panoramicX-ray michinaiva neanotevera exposure factor controls: milliamps (mA), kilovolts (kVp), uye nguva.Musiyano mukuru pakati pemichina miviri ndeye kutonga kweiyo exposure parameters.Kazhinji, intraoral X-ray zvishandiso zvinowanzove zvakagadziriswa maA uye kVp zvidzoreso, nepo kuratidzwa kunosiyana nekugadzirisa nguva yeakananga intraoral fungidziro.Kuratidzwa kwepanoramic X-ray unit inodzorwa nekugadzirisa complementary parameters;nguva yekuratidzira yakagadziriswa, nepo kVp uye mA inogadziriswa maererano nekukura kwemurwere, kureba, uye mapfupa emapfupa.Nepo musimboti wekushanda wakafanana, chimiro cheiyo exposure control panel yakanyanya kuoma.
Milliampere (mA) Kudzora - Inogadzirisa yakaderera-voltage magetsi nekugadzirisa huwandu hwemaerekitironi anoyerera mudunhu.Kuchinja maA kurongedza kunokanganisa huwandu hweX-rays inogadzirwa uye density yemufananidzo kana rima.Kuchinja zvakanyanya kuwanda kwemufananidzo kunoda mutsauko we20%.
Kilovolt (kVp) Kudzora - Inogadzirisa yakakwira voltage maseketi nekugadzirisa mutsauko ungangoita pakati pemagetsi.Kushandura kV kuseta kunogona kukanganisa kunaka kana kupinda kweX-rays inogadzirwa uye mutsauko mukusiyana kwemufananidzo kana density.Kuti uchinje zvakanyanya kuwanda kwemufananidzo, mutsauko we5% unodiwa.
Kudzora Nguva - Inoronga nguva iyo maerekitironi anoburitswa kubva mucathode.Kuchinja nguva yekumisikidza kunokanganisa huwandu hweX-ray uye density yemufananidzo kana rima mune intraoral radiography.Iyo nguva yekuratidzwa mupanoramic imaging yakagadziriswa kune chaiyo unit, uye kureba kwenguva yese yekuratidzwa iri pakati pegumi nematanhatu ne20 masekonzi.
Automatic Exposure Control (AEC) chinhu cheimwe panoramicX-ray michinaiyo inoyera huwandu hwemwaranzi inosvika kune inogamuchira mufananidzo uye inogumisa preset apo mugamuchiri anogashira inodiwa mwaranzi kusimba kuti ibudise inogamuchirika yekuongorora mufananidzo kuratidzwa.AEC inoshandiswa kugadzirisa huwandu hwemwaranzi inounzwa kumurwere uye kukwenenzvera kusiyanisa kwemifananidzo uye kuwanda.
