CT z elektronskim snopom (EBCT)

Štrukelj, Mojca (author), Medič, Mojca (author)

Tehnologija 5. generacije CT-jev, je bila izumljena predvsem z namenom prikazovanja utripajočega srca, ki je veliko let predstavljala hudo omejitev pri uporabi CT-ja. Hitro pridobivanje slik nam omogoči odsotnost mehanskega gibanja rentgenske cevi in detektorjev, ki je bila potrebna pri prejšnjih generacijah računalniške tomografije. EBCT je zaradi svoje visoke časovne ločljivosti odličen za prikazovanje srca. Zaradi izjemne hitrosti slikanja ni potrebno uporabiti beta blokatorjev, ki so lahko nevarni pri pacientih s slabotnim srcem. Pri EBCT preiskavi je lahko dozna obremenitev do desetkrat nižja v primerjavi z MDCT tehnologijo. Poleg tega je edini tomograf, ki ga je odobrila FDA (angl. Food and Drug Administration).

Abstract

Primary purpose of invention of the fifth generation CT system technology was to display a beating heart, which had been a great restriction in the use of the CT system for many years. Fast imaging enables absence of mechanical movement of the x-ray tube and of the detectors, which was inevitable with the previous generations of computed tomography. Due to its high time resolution, EBCT is excellent for displaying the heart. It offers an exceptional imaging speed, therefore the use of the beta blockers, which can present a risk in weak-heart patients, is not required. In case of the EBCT examination the dose can be up to ten times lower, compared to the MDCT technology. In addition, this is the only tomograph approved by FDA.
