A semiflexible 64-channel receive-only phased array for pediatric body MRI at 3T.

ABSTRACT:

Purpose

To design, construct, and validate a semiflexible 64-channel receive-only phased array for pediatric body MRI at 3T.

Methods

A 64-channel receive-only phased array was developed and constructed. The designed flexible coil can easily conform to different patient sizes with nonoverlapping coil elements in the transverse plane. It can cover a field of view of up to 44 × 28 cm(2) and removes the need for coil repositioning for body MRI patients with multiple clinical concerns. The 64-channel coil was compared with a 32-channel standard coil for signal-to-noise ratio and parallel imaging performances on different phantoms. With IRB approval and informed consent/assent, the designed coil was validated on 21 consecutive pediatric patients.

Results

The pediatric coil
