1. An arrangement for magnetic resonance imaging, the arrangement comprising:
a base structure having a variable shape,
a radio frequency (RF) coil arranged on or in the base structure,
an actuator coupled to the base structure such that the base structure is deformable along and/or about at least one axis in response to driving the actuator,
a position detecting sensor adapted to detect a current position of at least a portion of a subject to be examined relative to the RF coil, and
a controller coupled to the position detecting sensor and the actuator,
wherein the controller is adapted to adjust the variable shape of the base structure to maintain a contact of an outer surface of the base structure and/or the RF coil with at least the portion of the subject by driving the actuator in response to a detected change of the current position of the portion of the subject to be examined relative to the RF coil, compared with a previous position of the portion of the subject to be examined relative to the RF coil,
wherein the position detecting sensor is adapted to operate in a sampling rate to detect an organ displacement of the subject, wherein detection of the organ displacement controls the actuator.
