Ndezvipi zvikamu zve panoramic x-ray?

 

1) Sisitimu yekugadzira X-ray

Chiteshi cheX-ray chemazino chinoonekwa panoramic (semuenzaniso, TOSHIBA D-051)

Chubhu iyi ndiyo moyo wehurongwa. Inoshandura simba remagetsi kuita X-ray ichishandisa:

• Cathode/filamentkuburitsa maerekitironi
• Anode/chinangwakugadzira maX-ray kana maerekitironi akarova
• Dzimba dzemachubhunekudzivirira nemafuta ekudzivirira kupisa uye kudzora kupisa

Mumabasa epanoramic, chubhu inofanira kutsigira kubuda kwakagadzikana panguva yekuratidzwa kakawanda. Panyaya yekiriniki, kugadzikana kunokanganisa kuwanda kwemufananidzo uye kusiyana kwawo; mukushanda kwayo, kunokanganisa mwero wekutorwazve kwemifananidzo uye hupenyu hwechubhu.

Zvinonyanya kutariswa nevatengi muChiteshi cheX-ray chemazino chinoonekwa panoramic(kusanganisira mamodheru akaita seTOSHIBA D-051) zvinosanganisira:

• Kugadzikana kwenzvimbo yekutarisa(inobatsira kuchengetedza kupinza)
• Kushanda kwekupisa(kushanda kwakavimbika mumakiriniki ane vanhu vakawanda)
• Kuenderananejenareta uye simbi yemuchina ye panoramic unit

Kunyangwe kuvandudzwa kudiki mukugadzikana kwemachubhu kunogona kuderedza kudzokorora kwekutorwa kwechubhu. Semuenzaniso, kuderedza kudzokorora kwekutorwa kwechubhu kubva pa5% kusvika ku2% mukiriniki ine huwandu hwakawanda kunovandudza zvakananga kufambisa kwechubhu uye kunoderedza kuratidzwa kwemwaranzi nevarwere.

Jenareta yeHigh-Voltage

Iyi module inopa:

• kV (voltage yechubhu): inodzora simba remwaranzi uye kupinda mukati
• mA (chubhu yemagetsi)uye nguva yekuratidzwa: inodzora huwandu hwemufananidzo uye kuwanda kwemifananidzo

Masisitimu mazhinji epanoramic anoshanda munzvimbo dzakadai se60–90 kVuye2–10 mAzvichienderana nehukuru hwemurwere uye nzira yekutora mifananidzo. Kubuda kwejenareta nguva dzose kwakakosha; kusvetuka kana kusvetuka kunogona kuoneka sekupenya kusingaenderane kana ruzha.

2) Kugadzira Matanda uye Kudzora Dose

Collimator uye Filtration

• Collimatorinotetepa danda kusvika padanho rejometri rinodiwa (kazhinji kacho kanotsemuka katete kuti pave nekufamba kwepanoramic).
• Kusefa(yakawedzerwa aruminiyamu yakaenzana) inobvisa ma photon ane simba shoma anowedzera dose pasina kuvandudza kunaka kwemufananidzo.

Zvakanakira: kusefa nekusanganisa zviri nani zvinogona kuderedza kuratidzwa kwechirwere zvisina kufanira ukuwo zvichichengetedza ruzivo rwekuongorora chirwere—zvakakosha pakutevedzera mitemo uye kuva nechivimbo chemurwere.

Kudzora Kuonekwa / AEC (kana yakagadzirirwa)

Mamwe mayuniti ane zvinhu zvinongoerekana zvaonekwa zvinogadzirisa zvinobuda zvichienderana nehukuru hwemurwere, zvichivandudza kugara zvakanaka uye zvichibatsira kuderedza kudzokorora kwezviratidzo.

3) Sisitimu Yekufamba Kwemakanika

Panoramic unit haisi X-ray isingachinji. Mufananidzo wacho unoumbwa uku tubehead ne detector zvichitenderera murwere.

Zvikamu zvikuru:

• Ruoko runotenderera / gantry
• Mota, mabhandi/magiya, uye ma encoders
• Mhete dzinotsvedza kana sisitimu yekugadzirisa tambo

Ma encoders uye calibration yekufamba zvakakosha zvikuru nekuti panoramic sharpness inoenderana nekufamba kwakabatana. Kana nzira yekufamba isina kushanda, unogona kuona kukanganiswa, zvikanganiso zvekuwedzera, kana kusanzwisisika kwemaumbirwo emuviri—matambudziko anowanzo fungidzirwa zvisirizvo nechubhu kana chikonzero chiri che mechanical alignment.

4) Sisitimu yekugamuchira mifananidzo

Zvichienderana nekugadzirwa kwemidziyo:

• Masensa edhijitari(CCD/CMOS/flat-panel) ndiyo inonyanya kushandisa masisitimu emazuva ano
• Masisitimu ekare anogona kushandisaMaplate ePSPkana kuti zvinogamuchira zvakagadzirwa nefirimu

Zvinhu zvinotariswa nevatengi nezvekushanda zvakanaka:

• Kugadziriswa kwenzvimbo(kuonekwa kwakadzama)
• Kuita ruzha(kukwanisa kushandisa mushonga wakaderera)
• Rudzi rwekuchinja-chinja(inobata huwandu hwakasiyana hwemaronda eshaya)

Masisitimu edhijitari anogona kuvandudza mashandiro ebasa nekupfupisa nguva yekuwana-ku-kuona kuita masekonzi, inova mukana unoyerwa wekubudirira mumabasa evane zvigaro zvakawanda.
