A size-adaptive RF coil for MRI of the pediatric human brain at 7 T.

ABSTRACT:

Purpose

The purpose of this work was to design and build a size-adaptive pediatric RF head coil for 7 T neuroimaging. The coil can be safely applied for imaging children 4-9 years old.

Methods

The pediatric head coil incorporates eight, transmit dipole elements for operation in parallel transmit (pTx) mode. The receive architecture is comprised of a 32-channel conformal, size-adaptive receive array. Receive elements were arranged into five sections of a mechanically adjustable 3D printed head former, allowing adjustment of the receive array according to child head size. The transmit coil was carefully simulated to calculate specific absorption rate (SAR) and B₁ ⁺ efficiency. Coil performance was then evaluated with a pediatric head phantom at both the l
