Motion detection associated with a body part

A method for determining a motion associated with a body part of a patient, the method comprising:

• obtaining, from a color image sensor installed inside a medical scanner, a first color image of the patient inside the medical scanner and a second color image of the patient inside the medical scanner, wherein the first color image depicts the patient in a first state and the second color image depicts the patient in a second state;
• identifying, using a first machine learning (ML) model, a first area in the first color image that corresponds to the body part of the patient;
• identifying, using the first ML model, a second area in the second color image that corresponds to the body part of the patient;
• extracting a first plurality of features from the first area of the first color image and a second plurality of features from the second area of the second color image;
• determining a preliminary motion of the body part of the patient based on the first plurality of features and the second plurality of features;
• calculating a movement of the medical scanner between a time when the patient is in the first state and a time when the patient is in the second state;
• and
• determining the motion of the body part of the patient by subtracting the calculated movement of the medical scanner from the preliminary motion of the body part.
