Nyanzvi dzinoti mifananidzo yechinyakare yekurapa, inoshandiswa kuongorora, kuongorora kana kurapa zvimwe zvirwere, yagara ichinetsa kuwana mifananidzo yakajeka yevarwere vane ganda dema.
Vaongorori vakazivisa kuti vakawana nzira yekuvandudza mifananidzo yezvekurapa, zvichibvumira vanachiremba kuona mukati memuviri, zvisinei neruvara rweganda.
Zvakawanikwa zvitsva zvakaburitswa mumagazini yePhotoacoustics yaGumiguru. Boka revaongorori rakaita bvunzo pamaoko evanhu gumi nevasere, kusanganisira vanhu vane mavara akasiyana-siyana eganda. Zvakawanikwa zvavo zvakaratidza hukama huripo pakati pehuwandu hwezvinhu zvakasanganiswa, kukanganiswa kwechiratidzo chephotoacoustic chinokanganisa kujeka kwemifananidzo, uye rima reganda.
"Ganda rinoshanda senzira yekutumira ruzha, asi haritumire ruzha rwakafanana rwunowanikwa mu ultrasound. Pane kudaro, ruzha runopararira mukati mese uye runokonzera kuvhiringidzika kukuru," akadaro Bell. "Nekuda kweizvozvo, kupararira kweruzha nekuda kwekutorwa kwe melanin kunowedzera kuva dambudziko sezvo huwandu hwe melanin huchikwira."
Kuchinja maitiro
Tsvagiridzo iyi, yakaitwa pamwe chete nevaongorori vekuBrazil avo vaive neruzivo rwekare neimwe yemaalgorithms aBell, yakaratidza kuti chiyero chesignal-to-noise, chiyero chesainzi chekuenzanisa simba resignal neruzha rwekumashure, chakawedzerwa pamhando dzese dzeganda apo vaongorori vakashandisa nzira inozivikanwa se "short-lag spatial coherence beamforming" panguva yemifananidzo yekurapa. Iyi nzira, yakatanga yakagadzirirwa ultrasound imaging, ine mukana wekuti ishandiswe mumifananidzo ye photoacoustic.
Nzira iyi inosanganisa matekinoroji echiedza neultrasound kugadzira nzira itsva yekufungidzira mifananidzo yezvekurapa, sezvakatsanangurwa naTheo Pavan, uyo anoshanda nedhipatimendi refizikisi paYunivhesiti yeSão Paulo muBrazil. Sekureva kwaPavan, tsvakiridzo yavo yakasimbisa kuti nzira iyi itsva hainyanyi kukanganiswa neruvara rweganda, zvichikonzera kunaka kwemufananidzo zvichienzaniswa nenzira dzechinyakare dzinoshandiswa mumunda uyu.
Vaongorori vakaona kuti chidzidzo chavo ndicho chekutanga chekuongorora ganda nenzira kwayo uye kupa humbowo hwemhando yepamusoro uye hwehuwandu hunoratidza kuti chiratidzo cheganda chine simba uye zvinhu zvisina kurongeka zvinowedzerwa sezvo huwandu hwe melanin muganda huchiwedzera.
Kufunga patsva kwakakura muhutano
Zvakawanikwa nevaongorori zvinogona kuva nemigumisiro yakakura mukusimudzira kuenzana kwehutano pamwero wakakura. Dr. Camara Jones, chiremba wemhuri, nyanzvi yezvirwere, uye aimbova purezidhendi weAmerican Public Health Association, uyo asina kubatanidzwa muchidzidzo ichi, akaratidza rusaruro mu tekinoroji yesainzi pakusarudza zvigadzirwa zvinoshanda zvakanyanya kune vanhu vane ganda rakajeka. Jones akasimbisa kuti kushandisa rudzi sechinhu chinokonzera njodzi kuhutano inyaya yakakosha, sezvo iri magariro evanhu akavakirwa padudziro dzechitarisiko chemuviri kwete zvinhu zvehupenyu. Akataura nezvekushaikwa kwemajini emhando yerudzi mu genome remunhu sehumbowo hwekutsigira izvi. Tsvagiridzo yekare yakaratidzawo rusaruro muganda mu tekinoroji yekurapa, nekuwana kwakaratidza kuti michina yekurapa inoshandisa infrared sensing inogona kusashanda zvakanaka paganda rakasviba nekuda kwekukanganiswa nekuratidzwa kwechiedza.
Bell akaratidza tariro yekuti tsvakiridzo yake inogona kuvhura mukana wekubvisa rusaruro muhutano uye kukurudzira vamwe kugadzira tekinoroji inobatsira vanhu vese, zvisinei neruvara rweganda ravo.
"Ndinotenda izvozvo nekukwanisa kuratidza kuti tinogona kugadzira nekuvandudza tekinoroji - izvo hazvingoshandi kune boka diki revanhu chete asi zvinoshanda kune vanhu vakawanda. Izvi zvinokurudzira zvikuru kwete boka rangu chete, asiwo mapoka pasi rose kuti atange kufunga nenzira iyi pakugadzira tekinoroji. Zvinobatsira vanhu vakawanda here?" Bell akadaro.

Sezvatinoziva tese, kukura kweindasitiri yemifananidzo yezvokurapa hakuparadzaniswi nekugadzirwa kwemidziyo yekurapa yakatevedzana - majekiseni ekudzivirira emhando dzakasiyana-siyana uye zvinodyiwa zvinotsigira - zvinoshandiswa zvakanyanya mundima iyi.
