1. A local coil matrix for a magnetic resonance tomograph, the local coil matrix comprising:

  • a first coil having two detachable coil segments; and

    a tuning device having a tuning element and a position detector,wherein the two detachable coil segments have electrical connecting elements configured to produce an electrical connection between the two detachable coil segments in different relative positions of the two detachable coil segments to each other,wherein the tuning device is configured to tune a resonance circuit, which the first coil has in different relative positions of the two detachable coil segments of the first coil, to a predetermined resonance frequency,wherein the position detector of the tuning device is configured to determine a relative position of the two detachable coil segments to each other, andwherein the tuning device is configured to alter a parameter of the tuning element as a function of the relative position such that the resonance circuit is tuned to the predetermined resonance frequency.
