Impuguke zivuga ko amashusho gakondo y’ubuvuzi, akoreshwa mu gusuzuma, gukurikirana cyangwa kuvura indwara zimwe na zimwe, amaze igihe kinini agorwa no kubona amashusho asobanutse neza y’abarwayi bafite uruhu rwijimye.
Abashakashatsi batangaje ko bavumbuye uburyo bwo kunoza amashusho y’ubuvuzi, butuma abaganga bashobora kwitegereza imbere mu mubiri, hatitawe ku ibara ry’uruhu.
Ibyavumbuwe vuba aha byasohotse mu kinyamakuru Photoacoustics cyo mu Ukwakira. Itsinda ry'abashakashatsi ryakoze ibizamini ku maboko y'abakorerabushake 18, bikubiyemo abantu bafite uruhu rutandukanye. Ibyo bavumbuye byagaragaje isano iri hagati y'urwego rw'akajagari, kugoreka ikimenyetso cy'amajwi y'amajwi bigira ingaruka ku buryo amashusho agaragara neza, n'umwijima w'uruhu.
Bell yagize ati: “Uruhu rukora nk'igikoresho cyo kohereza amajwi, ariko ntirwohereza ubwoko bumwe bw'amajwi agaragara muri ultrasound. Ahubwo, amajwi arakwirakwira hose kandi agatera urujijo rukomeye. Kubera iyo mpamvu, gukwirakwira kw'amajwi bitewe no kwinjiza melanin birushaho kuba ikibazo uko umubare wa melanin wiyongera.”
Guhindura tekiniki
Ubushakashatsi bwakozwe ku bufatanye n'abashakashatsi bo muri Brezili bari bafite ubunararibonye mbere muri imwe muri algorithms za Bell, bwagaragaje ko igipimo cy'urusaku hagati y'ibimenyetso n'urusaku, igipimo cya siyansi cyo kugereranya imbaraga z'ibimenyetso n'urusaku rw'inyuma, cyariyongereye ku ruhu rwose ubwo abashakashatsi bakoresheje uburyo buzwi nka "short-lag spatial coherence beamforming" mu gihe cyo gufata amashusho y'ubuvuzi. Ubu buryo, bwabanje gukoreshwa mu gufata amashusho ya ultrasound, bufite ubushobozi bwo gukoreshwa mu gufata amashusho y'amajwi n'amajwi.
Ubu buryo buhuza ikoranabuhanga ry’urumuri na ultrasound kugira ngo habeho uburyo bushya bwo gufata amashusho mu buvuzi, nk’uko byasobanuwe na Theo Pavan, ukorera mu ishami rya fiziki muri Kaminuza ya São Paulo muri Brezili. Nk’uko Pavan abivuga, ubushakashatsi bwabo bwemeje ko ubu buryo bushya budahinduka cyane n’ibara ry’uruhu, bigatuma ishusho iba nziza ugereranyije n’uburyo busanzwe bukoreshwa muri urwo rwego.
Abashakashatsi bavuze ko ubushakashatsi bwabo ari bwo bwa mbere bwo gusuzuma imiterere y'uruhu mu buryo buboneye no gutanga ibimenyetso by'imiterere n'imibare bigaragaza ko ikimenyetso cy'amajwi y'uruhu n'ibintu bidafite aho bihuriye n'imiterere y'uruhu byiyongera uko ingano ya melanin mu gice cy'imbere cy'uruhu yiyongera.
Gusubiramo ibitekerezo mu buvuzi
Ibyo abashakashatsi bavumbuye bishobora kugira ingaruka zikomeye mu guteza imbere uburinganire mu buvuzi ku rwego rwagutse. Dr. Camara Jones, umuganga w’umuryango, inzobere mu by’indwara z’ibyorezo, akaba n’uwahoze ari perezida w’ishyirahamwe ry’ubuvuzi rusange rya Amerika, utari muri ubu bushakashatsi, yagaragaje ko ivangura rishingiye ku ikoranabuhanga rya siyansi rikoreshwa mu gushakira abantu ibintu bifitiye akamaro abantu bafite uruhu rwerurutse. Jones yashimangiye ko gukoresha ubwoko nk'ikintu gishobora guteza akaga ku buzima ari ikibazo gikomeye, kuko ari imiterere y’imibereho ishingiye ku buryo sosiyete isobanura imiterere y’umubiri aho kuba ibintu by’ibinyabuzima. Yagaragaje ko nta shingiro rya genetiki rishingiye ku bwoko bw’umuntu mu ngirabuzimafatizo nk'ibimenyetso bishyigikira iki gitekerezo. Ubushakashatsi bwakozwe mbere bwagaragaje ko ivangura rishingiye ku ruhu mu ikoranabuhanga ry’ubuvuzi, aho ibyavumbuwe bigaragaza ko ibikoresho by’ubuvuzi bikoresha infrared sensing bishobora kudakora neza ku ruhu rwijimye bitewe n’uko bishobora kubangamira urumuri.
Bell yagaragaje icyizere ko ubushakashatsi bwe bushobora gufungura amarembo yo kurandura ivangura mu buvuzi no gushishikariza abandi guhanga ikoranabuhanga rifitiye akamaro abantu bose, hatitawe ku ibara ry'uruhu rwabo.
“Ndizera ko hamwe n’ubushobozi bwo kugaragaza ko dushobora guhanga no guteza imbere ikoranabuhanga — ibyo ntibikorera itsinda rito ry’abaturage gusa ahubwo bikorera n’abaturage benshi. Ibi ni ibintu bitera imbaraga cyane, atari itsinda ryanjye gusa, ahubwo no ku matsinda yo hirya no hino ku isi, gutangira gutekereza kuri iki cyerekezo mu gihe cyo gushushanya ikoranabuhanga. Ese rifasha abaturage benshi?” Bell yagize ati.

Nkuko twese tubizi, iterambere ry’inganda zikora amashusho y’ubuvuzi ntaho ritandukaniye n’iterambere ry’ibikoresho bitandukanye by’ubuvuzi - injectors zikoresha ikoranabuhanga ritandukanye n’ibindi bikoresho bizifasha - bikoreshwa cyane muri uru rwego. Mu Bushinwa, buzwiho inganda zikora, hari inganda nyinshi zizwi cyane mu gihugu no mu mahanga mu gukora ibikoresho by’ubuvuzi, harimoLnkMedKuva yashingwa, LnkMed yibanda ku bijyanye n'injection zikoresha umuvuduko mwinshi. Itsinda ry'abahanga rya LnkMed riyobowe n'impamyabumenyi y'ikirenga (PhD) ifite uburambe bw'imyaka irenga icumi kandi ikora cyane mu bushakashatsi no mu iterambere. Iyobowe na we,Inshinge ya CT imwe mu mutwe,Inshinge ya CT ifite imitwe ibiri,Inshinge zo mu bwoko bwa MRI, naInshinge zikoresha umuvuduko mwinshi wa angiographybyakozwe hamwe n'ibi bintu: umubiri ukomeye kandi muto, uburyo bworoshye bwo gukora kandi bufite ubwenge, imikorere yuzuye, umutekano mwinshi, n'igishushanyo mbonera kirambye. Dushobora kandi gutanga seringe na tubes bihuye n'ibyo bicuruzwa bizwi cyane bya CT, MRI, DSA injectors Kubera imyumvire yabo ivuye ku mutima n'imbaraga zabo z'umwuga, abakozi bose ba LnkMed baragutumiye rwose kuza gusura andi masoko hamwe.
