Abstract

7T MRI is a promising candidate for detecting carotid plaques prematurely. Specialized antenna are required for imaging of different body parts, along with coilformers to hold the antenna close to the desired body area. A fractionated dipole antenna is simulated and fabricated, in order to test the performance of the antenna and coilformer, in imaging the carotid region. 7T MRI test showed a 86% magnetic field strength reduction in a makeshift phantom, at approximate carotids depth, compared to the magnetic field at the skin of the phantom.
