Isuzuma rya X-ray computed tomography (CT) ryahinduye cyane uburyo bwo gufata amashusho mu buvuzi, ritanga amashusho arambuye y’umubiri w’umuntu. Icy’ingenzi mu mikorere ya sisitemu ya X-ray CT ni umuyoboro wa X-ray, utanga imiyoboro ya X-ray ikenewe mu gufata amashusho. Iterambere riheruka ry’ikoranabuhanga ryashyizeho uburyo bwo gupima intera ihindagurika (VFDDs) muri sisitemu ya X-ray CT, bunoza ubwiza bw’ishusho n’ubushobozi bwo gusuzuma. Iyi nkuru irasuzuma ibyiza bya VFDD muri sisitemu ya X-ray CT n’uburyo ikorana n’imiyoboro ya X-ray kugira ngo irusheho kunoza umusaruro w’abarwayi.
Gusobanukirwa intera ihindagurika ry'igipimo cy'ibanga
Uburyo bwo gupima ibintu buhinduka (variable focus detector) busobanura ubushobozi bwa sisitemu ya X-ray CT mu guhindura intera iri hagati y’umuyoboro wa X-ray na detector. Ubusanzwe sisitemu za CT zikoresha uburyo bwo gupima ibintu buhoraho, bugabanya ubushobozi n’ubwiza bw’ishusho. Binyuze mu gushyigikira uburyo bwo gupima ibintu buhinduka (variable focus), sisitemu za CT zigezweho zishobora kunoza uburyo bwo gufata amashusho hashingiwe ku bisabwa byihariye bya buri scan.
Ongera ireme ry'ishusho
Imwe mu nyungu z'ingenzi za VFDD muri sisitemu ya X-ray CT ni uko ishusho irushaho kuba nziza cyane. Mu guhindura uburebure bw'inyuma, sisitemu ishobora kongera ubushobozi bwo kureba no gutandukanya ibintu, bigatuma habaho amashusho asobanutse neza kandi arambuye. Ibi ni ingirakamaro cyane cyane mu bice bigoye by'umubiri, aho amashusho nyayo ari ingenzi kugira ngo hamenyekane neza. Umuyoboro wa X-ray ugira uruhare runini muri iki gikorwa, kuko ushobora gupimwa hashingiwe ku burebure bw'inyuma bwahinduwe kugira ngo haboneke urugero rwiza rw'imirasire, bigatuma isura y'ishusho ikomeza kumera neza nta kibazo.
Kongera ubushobozi bwo gukoresha igipimo
Indi nyungu yo kubona intera ihindagurika ry’aho umuntu anyura ni uko ingano y’umuti ikoreshwa neza. Muri sisitemu zisanzwe zikoreshwa mu gupima, urugero rw’imirasire rukunze kuba rumwe uko imiterere y’agace gafata amashusho ingana kose. Ibi bishobora gutuma habaho imiterere idakenewe mu bice bimwe na bimwe no kudakoresha neza mu bindi. Hamwe na VFDD, umuyoboro wa X-ray ushobora guhindura imiterere y’imirasire bitewe n’intera iri hagati y’aho umuntu anyura, bigatuma imiterere y’umuti itangwa neza. Ibi ntibigabanya gusa imiterere y’imirasire y’umurwayi ahubwo binanoza umutekano w’uburyo bwo gufata amashusho.
Uburyo bworoshye bwo gufata amashusho
Gukoresha VFDD bituma habaho uburyo bworoshye bwo gukoresha porogaramu zo gufata amashusho. Abaganga bashobora guhindura uburebure bw'umurwayi bitewe n'ibyo umurwayi akeneye n'aho ahuriye n'ibyo akunda. Urugero, uburebure burebure bw'umurwayi bushobora kuba ingirakamaro cyane mu gufata amashusho y'ibice binini by'umubiri, mu gihe uburebure bugufi bw'umurwayi bushobora kuba bwiza ku nyubako nto kandi zigoye. Ubu buryo bwo guhuza ibintu butuma sisitemu za X-ray CT zishobora guhinduka bitewe n'imiterere itandukanye y'ubuvuzi, bigatuma ziba igikoresho cyiza cyo gufata amashusho.
Ivugurura rya 3D ryakozwe neza
Ibyuma bipima ibintu bitandukanye kandi bigira uruhare mu kunoza ubushobozi bwo kongera gukora amashusho mu buryo butatu (3D). Mu gufata amashusho ku ntera zitandukanye, sisitemu ishobora gukora ibishushanyo mbonera bya 3D by’imiterere y’umubiri neza. Ibi ni ingirakamaro cyane mu gutegura kubaga no gusuzuma uburyo bwo kuvura, aho amashusho ya 3D nyayo ari ingenzi kugira ngo habeho umusaruro mwiza. Kwizerwa kw’ibi byubakwa byongera ubushobozi bw’umuyoboro wa X-ray bwo gutanga amashusho ahoraho kandi meza ku ntera zitandukanye.
mu gusoza
Muri make, guhuza ibikoresho bipima intera ihindagurika (VFDDs) muri sisitemu ya X-ray CT bigaragaza iterambere rikomeye mu ikoranabuhanga ryo gufata amashusho mu buvuzi. Mu kunoza umubano uri hagati y’umuyoboro wa X-ray n’ibikoresho bipima, VFDDs yongera ireme ry’ishusho, yongera imikorere myiza y’ibipimo, kandi itanga uburyo bworoshye bwo gufata amashusho. Uko ishami rya radiyoloji rikomeza gutera imbere, ubu bushya nta gushidikanya buzatuma habaho ubushobozi bukomeye bwo gusuzuma no kunoza ubuvuzi bw’abarwayi. Ahazaza h’ibipimo bya X-ray CT ni heza, kandi VFDDs zizategura inzira yo gutanga ibisubizo by’amashusho binoze kandi binoze.
