Muchimanjemanje digital dentistry,intraoral mazino X-ray sensorszvave zvakakosha pakuongorora, kuronga kurapwa, uye kutaurirana kwevarwere. Kungave kuona kwekutanga caries, kuongorora midzi canal marapirwo, kana kuongorora mamiriro emapfupa, mhando yemufananidzo inokanganisa zvakananga kukiriniki.

Vazhinji vashandi vemazino vanobvunza mibvunzo yakafanana:

• Sensor yemazino inoshanda sei?
• Ndeupi musiyano uripo pakati peCCD neCMOS sensors?
• Sensor yemazino inofanira kugara kwenguva yakareba sei?
• Ndeipi nguva yekutsiva sensor yekuchembera?

Ichi chinyorwa chinotsanangura iyo inoshanda musimboti wemazino sensors, inofananidza CCD neCMOS tekinoroji, uye inopa nhungamiro inoshanda pane sensor lifespan uye kutsiva.

Iyo Dental X-ray Sensor Inoshanda Sei?

Kunyangwe akasiyana masensa tekinoroji aripo, anenge esemazuva ano mazino intraoral sensorstevera maitiro akafanana ekufungidzira.

Danho 1. X-rays Inopfuura NemuZino

Panguva yekuongorora, X-ray danda rinopinda mumazino omurwere uye pfupa rakapoteredza. Matishu akasiyana anotora huwandu hwakasiyana hwemwaranzi, achigadzira akasiyana eX-ray intensity.

Danho 2. Iyo Scintillator Inoshandura X-rays kuita Chiedza Chinooneka

Yekutanga layer mukati me sensor ndiyoscintillator (fluorescent layer).

Basa rayo nderekushandura maX-rays asingaonekwe kuita mwenje unooneka unogona kuona chip yekufungidzira.

Iyi nhanho ndeimwe yeakanyanya kukoshesa zvikamu zve sensor yese nekuti inonyanya kutarisisa kupenya kwemufananidzo, kupinza, uye musiyano.

Nhanho 3. Iyo CMOS Imaging Chip Inobata Chiedza

Chiedza chinooneka chinosvika mamirioni emapikseli emicroscopic paCMOS imaging chip.

Pixel yega yega inoshandura mwenje kuita yekuchaja yemagetsi.

Danho 4. Digital Processing Inogadzira Mufananidzo

Zviratidzo zvemagetsi zvinogadziriswa nemagetsi uye zvinoendeswa kune software yekufungidzira.

Mumasekondi mashoma, murapi anogashira mufananidzo wemazino we grayscale unogona kuratidza:

• Dental caries
• Periapical maronda
• Root canal anatomy
• Periodontal bone kurasikirwa
• Trabecular bone structure
• Mazino akabatwa

CCD vs CMOS: Ndeupi Musiyano?

Makore apfuura, mazino sensors ainyanya kushandiswa cheroCCD (Charge-Coupled Device)kanaCMOS (Complementary Metal-Oxide Semiconductor)teknolojia.

Sezvineiwo,matekinoroji ese ari maviri anoburitsa mifananidzo achishandisa iyo chaiyo X-ray yekushandura maitiro. Musiyano mukuru chete ndewekuti machaji emagetsi anoverengwa sei kubva kune sensor.

Nei CMOS Yave Iyo Indasitiri Standard?

Makore makumi maviri apfuura, CCD yakapa mhando yemhando yepamusoro.

Zvisinei, kufambira mberikumashure-yakavhenekerwa (BSI) CMOS tekinorojivakavandudza maitiro zvinoshamisa.

Nhasi CMOS sensors inopa:

• Higher imaging speed
• Kuderedza simba rekushandisa
• Zvirinani kugadzira kuenderana
• Yakaderedzwa mari yekugadzira
• Yakanakisa mufananidzo mhando
• Kunyanya kusimba

Semagumo,dzinenge dzese dzemazuva ano intraoral sensors dzinoshandisa tekinoroji yeCMOS.

CCD tekinoroji inoramba iri muhunyanzvi hwekutsvagisa kwesainzi uye mamwe epamusoro-ekupedzisira maindasitiri ekufungidzira masisitimu.

Chii chinosarudza Hupenyu hweMeno Sensor?

Vanhu vazhinji vanofungidzira kuti CMOS chip inopedzisira yapera.

Chokwadi,iyo imaging chip haiwanzo chikamu chekutanga kutadza.

Iyo Scintillator Inosarudza Sensor Hupenyu

Thescintillator layerine mhosva yezvinenge80% yehurefu hwemhando yemifananidzo.

Kwemakore ekushandiswa kwezuva nezuva, zvinhu zvakati wandei zvishoma nezvishoma zvinoderedza kuita kwayo.

1. Kuenderera mberi kweX-ray Exposure

Kudzokororwa X-ray kuratidzwa zvishoma nezvishoma kuchembera zvinhu zvephosphor.

Sezvo simba rekushandura chiedza richiderera, mifananidzo inova:

• Zvishoma kupenya
• Kudzika mukusiyana
• Zvakaoma kududzira

2. Chemical Disinfection

Kucheneswa nguva nenguva uye kuuraya hutachiona kunogona kukanganisa zvishoma nezvishoma nzvimbo yekudzivirira ye sensor.

Nokufamba kwenguva, ma disinfectants anogona kubatsira kune:

• Localized cloudiness
• Image haze
• Permanent rima mavara

Kudzivirirwa kwakaringana nedziviriro uye nekugadzira-inokurudzirwa nzira dzekuchenesa dzinogona kubatsira kuderedza njodzi iyi.

3. Mechanical Stress

Mazino emazino anonzwa kushushikana kwakanyanya kwemuviri panguva yekushandiswa kwezuva nezuva.

Kudzokororwa kuruma kudzvinyirirwa, kudonha netsaona, kana kukanganisa kunogona kukuvadza zvachose scintillator layer, zvichitungamira ku:

• Fixed image artifacts
• Nzvimbo dzakafa
• Permanent dark marks

Iyo CMOS Chip Inopera Here?

Mumamiriro ezvinhu ekiriniki,CMOS machipisi akasimba zvakanyanya.

Izvo zvikamu zvemagetsi zvinowanzo kwanisa kushanda8-10 makore kana kupfuuravasati vaona kuparara kwemagetsi kunooneka.

Kazhinji, kunaka kwemufananidzo kunodererazvakanaka pamberi chip pachayo kusvika kumagumo ehupenyu hwayo, kunyanya nekuti scintillator layer inotanga kushatisa.
