Wall shear stress (WSS) plays an important role in the formation, growth, and rupture of atherosclerotic plaques arteries. This study measured WSS diseased carotid artery phantoms with degrees stenosis varying from 0 to 60% both steady pulsatile flow. Experiments were performed using silico real flow phantoms. Blood velocities estimated plane wave (PW) vector Doppler. was then velocity gradient...
PURPOSE The goal of this work was to develop phantoms for the optimization of pre-operative computed tomography (CT) scans of the prostate artery, which are used for embolization planning. METHODS Acrylonitrile butadiene styrene (ABS) pellets were doped with barium sulfate and extruded into filaments suitable for 3D printing on a fused deposition modeling (FDM) printer. Cylinder phantoms were...
UNLABELLED Currently, 2 types of phantoms (physical and computer generated) are used for testing and comparing tomographic reconstruction methods. Data from physical phantoms include all physical effects associated with the detection of radiation. However, with physical phantoms it is difficult to control the number of detected counts, simulate the dynamics of uptake and washout, or create mult...
