Abstract
The use of intravascular MRI imaging of vessels will provide high quality
images for improved diagnosis and treatment. An intravascular MR receive coil provides
high SNR because of proximity to the tissue but respiratory and cardiovascular motion
may affect the quality of acquired images. Parallel MRI provides a framework to reduce
the scan time using multiple coils. This article presents a novel design of a Phased Array
MR receive coil for intravascular imaging which can implement Parallel MRI. Cartesian
and Radial GRAPPA are used as the main reconstruction algorithms. We demonstrate
that Moving Segment Radial GRAPPA provides good image reconstruction with minimum
artifacts when data is under-sampled by a factor of 16.
