Transmit-Receive Array For High Field MRI

摘要

A multi-element MRI head coil is formed in the shape of a helmet that fits over the head of a subject to be imaged. The coil elements are separately driven by rf transmit channels during an MR scan to shape the rf fields produced in the region of interest. The head coil can be used in the transmit only phase of the scan, or it can be used in both the transmit and receive phases.
