Patent ID: 11163025

Abstract:
A telescoping magnetic resonance coil for a magnetic resonance imaging apparatus has a first coil half in a first coil housing, having a first coil support and a number of first coil units on the first coil support. The telescoping coil also has a second coil half in a second coil housing, having a second coil support and a number of second coil units on the second coil support. One end of the first coil housing is opposite to and slidable relative to one end of the second coil housing, and one end of the first coil support is opposite to and slidable relative to one end of the second coil support. The first coil units at the one end of the first coil support have connections to which sliding contacts of the second coil units at the one end of the second coil support are electrically connectable. The connections are slidable on the sliding contacts, and each of the sliding contacts is provided with a frequency compensation element that maintains a magnetic resonance frequency of the coil at a constant value.
