Title: ELASTIC RADIO FREQUENCY COIL
Abstract:
This specification describes RF coils using an elastic substrate that can be stretched and/or wrapped around the target anatomy. In some examples, a system includes an RF coil array including at least one elastic and conductive loop, the elastic and conductive loop having a length and being elastic in that, in response to a stress, the length stretches from a first length to a second length greater than the first length and returns to the first length after removal of the stress. The elastic and conductive loop is configurable to surround at least a portion of a magnetic resonance imaging subject's body for magnetic resonance imaging of the portion of the subject's body. The system includes an RF circuit coupled to the RF coil array and configured to cause a voltage to be induced through the elastic and conductive loop.
