Webphysiologically improved NCAT (PINCAT) phantom in which the signal intensities were modified for MRI application to validate a dynamic MR imaging scheme in real - time cardiac MRI. In [16 ], a moving phantom was generated by segmenting cardiac images from an in -vivo acquisition by using a random affine transformation to simu-late motion.
WebJan 1, 2007 · Using the phantom we simulate a realistic CMR scenario. Because the exact anatomy and physiological functions of the phantom are known, this provides a gold standard by which to evaluate the imaging technique and compare it to other methods. The paper is organized as follows. Section 2 introduces the proposed PINCAT phantom.
Web1) PINCAT data . We numerically simulate the acquisition of myocardial perfusion MRI data from a single short axis slice of the PINCAT phantom , . We set the phantom parameters to obtain realistic cardiac perfusion dynamics and contrast variations due to bolus passage, while accounting for respiration with variability in breathing motion. fennec shand brickheadzWebFig. 1.
