A table for an MRI system includes a top surface for supporting a patient being imaged and a motion sensor for sensing motion of the patient. The motion sensor is located below the top surface and includes a self-resonant spiral (SRS) coil and a coupling loop. The coupling loop generates a drive RF signal to excite the SRS coil to radiate a magnetic field having a predefined resonant frequency. The coupling loop also receives a reflection RF signal from the SRS coil. The motion sensor is located such that at least a portion of a torso of the patient being imaged is within the magnetic field. A controller is configured to detect patient motion based on the reflection RF signal.

The present disclosure provides a system and method for motion field generation and image correction. The method may include obtaining a plurality of first sets of magnetic resonance (MR) image data of an object generated based on a plurality of first sets of imaging sequences. The method may include obtaining a motion curve of the object. The method may include obtaining position emission tomography (PET) image data of the object generated in a scanning time period. The method may include generating one or more target motion fields corresponding to the scanning time period based on the plurality of first sets of MR image data and the motion curve. The method may include generating one or more corrected PET images by correcting, based on the one or more target motion fields, the PET image data.

A base for supporting a piezoelectric sensor comprising: a generally planar support frame having an upper side, a lower side, and an opening defined between the upper side and lower side; and a housing mounted in the opening, the housing including an upper portion and a lower portion, the upper portion including a sensor disposed therein and the lower portion includes a biasing member in contact with the sensor, wherein the sensor is biased by the biasing force of the biasing member against the upper portion of the housing, whereby the upper portion is in turn biased by the biasing force against a floor of a cage positioned on the upper side of the support frame.
