Study of B1 and SAR Field Distribution for loop coil with different bending angles at 3T.
The aim is to investigate the RF field behavior of flexing loop coils as resonant elements in flexible RF arrays. Numerical modeling and simulation of a mechanically flexible single channel RF coil at different bending angles for 3T MRI are implemented to determine the best bending angle that will generate highest B1 magnetic field inside imaging area with least flux cancellation at center. Results include B1 magnetic and SAR field distribution of the coronal, sagittal and transverse planes of phantom at 9 bent angles. It also includes the comparative quantitative analysis of magnetic field at different biological samples.
