9. A medical imaging system, comprising:
a medical imaging apparatus configured to perform a scan to acquire image data of a body part of the patient; and
an apparatus for repositioning a body part of a patient when using a medical imaging system to perform a scan, comprising:
a memory that stores a plurality of instructions; and
processor circuitry that couples to the memory and is configured to execute the plurality of instructions to:
obtain a first signal indicative of positional information of the body part of the patient that is being imaged in an imaging pose position;
determine a critical range based on a machine setting of the medical imaging system using a pre-trained machine-learning model, within which a motion artefact is correctable with the medical imaging system;
detect a change in the obtained first signal indicating a body motion of the patient;
determine whether a deviation of a position of the body part from the imaging pose position of the body part exceeds the determined critical range around the imaging pose position; and
transmit a control signal to the medical imaging apparatus to cause the medical imaging apparatus to perform an action in dependence upon a determination result.
 
14. A method for repositioning a body part of a patient when using a medical imaging system that comprises a medical imaging apparatus to perform a scan, comprising:
