A 32-channel receive array coil for bilateral breast imaging and spectroscopy at 7T.

ABSTRACT:

Purpose

This work describes the construction and evaluation of a bilateral 32-channel receive array for breast imaging at 7T.

Methods

The receive array consisted of 32 receive coils, placed on two 3D-printed hemispherical formers. Each side of the receive array consisted of 16 receive loops, each loop having a corresponding detachable board with match/tune capacitors, active detuning circuitry, and a balun. Coil performance was evaluated on homogeneous canola oil phantoms using a Philips Achieva 7T system. Array coil performance was compared with a bilateral forced current excitation volume coil in transmit/receive mode and with a previously reported 16-channel unilateral coil with a similar design.

Results

The 32-channel array had an increase in average SNR throughou
