We present a 19-channel, 2D coil array for large in vitro studies of human brain tissue, such as whole brain slices at 7 T. The sample is to be placed in a separate container horizontally between two of these arrays. The channels are amplified and decoupled from their neighbours by home-made low impedance low noise amplifiers. All adjacent elements show an isolation of > 26 dB, the circuit Q of an uloaded single element is on average 100.
