Knee-foot coil with improved homogeneity

摘要

A knee-foot coil provides side coils covering both a side of a tubular foot support and a side of an attached toe chamber. Homogeneity in the signals from these loops is provided by a shunt, separating these side coils into portions with different sensitivities. Upper and lower coils provide for vertical sensitivity, the upper coil optionally surrounding the toe chamber.
