Aortic regurgitation: assessment with 64-section CT.
PURPOSE To prospectively evaluate diagnostic accuracy of 64-section computed tomography (CT) for evaluation of aortic regurgitation (AR), with transthoracic echocardiography (TTE) as reference. MATERIALS AND METHODS The institutional review board approved this study; written informed consent was obtained. Thirty patients (23 men, seven women; mean age, 56.6 years) with AR underwent TTE and re...

Fuzzy control techniques are of interest for practical applications. Hence, it is important to understand their features. In this paper some results of computer-experimental analysis of behavior of a fuzzy controller for the cart-ball variant of inverted pendulum system are given. The impacts of changes in uncertainty in the controller are analyzed experimentally: it has been found that the per...
متن کاملPregled metoda za raspoznavanje lica
Sažetak – Prepoznavanje lica jedno je o najuspješnijih primjena analize slike i kao takvo si je priskrbilo dosta pažnje i proučavanja zadnjih godina. Razlog tome su razne komercijalne i policijske primjene kao i raspoloživost upotrebljivih tehnologija. Iako su današnji sustavi za prepoznavanje lica dosegli odreñenu zrelost postoji još otvorenih problema. Prepoznavanje u nekontroliranim uvjetima...
متن کاملWhole brain perfusion CT imaging and CT angiography with a 64-channel CT system
Due to the development of new computed tomography (CT) techniques over the last 30 years, there are a vast amount of new diagnostic options available today. When Sir G.N. Hounsfi eld invented CT [1] (based on the preliminary works of A. MacLeod Cormack), the acquisition of a single slice took more time than CT-angiography of the complete supraaortic circulation today. And, of course, the image ...
متن کاملEvaluation of MRI-based Polymer Gel Dosimetry for Measurement of CT Dose Index (CTDI) on 64 slices CT Scanners
Introduction: Computed tomography (CT) has numerous applications in clinical procedures but its main problem is its high radiation dose to the patients compared to other imaging modalities using x-ray. CT delivers approximately high doses to the nearby tissues due to the scattering effect, fan beam (beam divergence) and limited collimator efficiency. The radiation dose from multi-slice scanners...
