Evaluation of patient exposure with Flat Panel Detector (FPD) in X-ray TV system
The use of flat-panel detector (FPD) systems in TV equipment for gastrointestinal tract examination is increasing. The use of FPD systems is believed to reduce the exposure dose. When our institution changed its TV equipment from an image intensifier (GE;MS90Tj) system to an FPD (Shimadzu;SONIALVISION safire DAR-3500) system, we measured the doses produced and carried out a comparative examinat...
متن کاملA propensity score-based comparison of flat panel digital detector fluoroscopy versus digital cinefluoroscopy for coronary artery calcium detection.
INTRODUCTION Detection of coronary artery calcification (CAC) allows for a refined prediction of cardiovascular risk beyond global risk assessment algorithms. Newer-generation, high-resolution, flat-panel digital detector (FPDD) fluoroscopic systems may provide higher CAC detection rates compared with older fluoroscopic devices. METHODS We compared the CAC detection rates of two fluoroscopic ...
متن کاملAssessment of X-Ray Crosstalk in a Computed Tomography Scanner with Small Detector Elements Using Monte Carlo Method
Introduction: Crosstalk is a leakage of X-ray or light produced in a matrix of X-ray detectors or array of photodiodes in one element to other elements affecting on image contrast and spatial resolution. In this study, we assessed X-ray crosstalk in a computed tomography (CT) scanner with small detector elements to estimate the effect of various parameters such as X-ray tube voltage, detector e...
متن کاملThe design and imaging characteristics of dynamic, solid-state, flat-panel x-ray image detectors for digital fluoroscopy and fluorography.
Dynamic, flat-panel, solid-state, x-ray image detectors for use in digital fluoroscopy and fluorography emerged at the turn of the millennium. This new generation of dynamic detectors utilize a thin layer of x-ray absorptive material superimposed upon an electronic active matrix array fabricated in a film of hydrogenated amorphous silicon (a-Si:H). Dynamic solid-state detectors come in two basi...
متن کاملClinical Utility of Angiographic CT with a Flat-detector Angiographic System during Endovascular Procedure
OBJECTIVE We evaluated the feasibility of angiographic computed tomography (ACT) for visualizing stent material in patients who underwent intracranial or extracranial stent placement to treat atherosclerotic lesions or stent assisted coil embolization. MATERIALS AND METHODS We performed intrarterial and intravenous ACT on biplane angiography system equipped with flat panel detectors (Axiom Ar...
