Mifananidzo yemapapu inobatsira kudzidza mapapu nemubatsiro we X-rays. Rudzi rwakakurumbira zvikuru rwemafirimu inonzi fluorography . Iyo inowanikwa mune nzira yekugadzirisa, nekuda kwokuti murwere anogamuchira chirwere chiduku chemazuva, asi kuedza kunodhura. Mukuwedzera, nekukurumidza kwechigumisiro, saka, fluorography inowanikwa mune urongwa hwekuongorora kwegore negore. Asi chimbofunga imwe, inodzidzisa, mapoka emapapu X-rays.
Mifananidzo yemapapu ane mazai emvura mashoma
Mhando yekutanga yepapu X-ray machine yakanzi ine-pasi-dose kana CCD-detector. Chivigiro chake chakafukidzwa ne phosphor, saka zviri pachena kuti inoratidzika se terevhizheni muma80s. Kuverenga kunoitwa kuburikidza neirasi inonzi infrared inokurudzira phosphor.
Sezvo iri sangano rakagadzirwa makore anopfuura makumi matatu adarika, rine zvinetso zvaro:
- kuwedzera munguva yekutsvaga;
- fuzziness uye mashizha, kunyanya kumativi ose emifananidzo, ndicho chikonzero kukanganisa uku kwakanga kusingatorerwi kwenguva yakareba;
- pasi yakasarudzwa chisarudzo.
Izvo zvinokanganisa zvinokonzera mugumisiro wekuongororwa, sezvo zvisiri nguva dzose kugona kuziva zvirwere pamatunhu ekutanga ekusimbiswa. Ndicho chikonzero chigadzirwa chacho chakazadzikiswa, somugumisiro, zvigadzirwa zve digital zve X-ray yemapapu zvakagadzirwa.
Digital radiography yemapapupa
Izvozvi zvigadzirwa zvejeri zvehuwandu hwemapapu zvine zvinyorwa zvisingaverengeki, pakati payo ndiyo shanduro yakareruka yemufananidzo, iyo isingabatanidzi kukura kwechifananidzo, kana ichichengetwa mumakombiyuta ekuyeuka uye inoramba iripo kwenguva yakakwana.
Imwe nzira inokosha inoshandiswa yemichina yemazuva ano inhu hwakanaka hwechifananidzo, isina zvisikwa zvose uye zvinoputika, kunyange pamiganhu. Nokuda kwechikonzero chakajeka chekudzidza, chiremba anogona kuona chero shanduko mumapapu, saka chiitiko chekurapa chinowedzera.
Vakawanda vanotya kuti zvigadzirwa zvemagetsi zvinosvibisa zvakawanda kupfuura zvakatangira. Iko mafungiro asina kukanganisa, sezvo zvigadzirwa zvemazuva ano zvisingaiti hazvo chete zvinopfuura kudarika kwemajekiseni, asiwo zvinobudisa emitambo shoma shoma. Nokudaro, nhasi zvinoshandiswa zvinopiwa kune mhando itsva yemichina ye-X-ray.
Mune zviitiko zvipi mapapu radiography anoongororwa?
X-ray kuongorora mapapu kunoitwa nechirwere chekufema, kureva:
- tuberculosis ;
- pneumonia;
- marudzi akasiyana-siyana ebronchitis;
- ronda;
- zvirwere zvemapapu emabasa ekusiyana kwakasiyana.
Mifananidzo yemapapu ane pneumonia inoratidzira shallow focal shading. Kana pane chivharo mumapapu, zvino tinokwanisa kutarisa kuvapo kwechirwere chetachiona kana kuparadzaniswa kwechirwere.
