Determining couch frame shift

An apparatus, comprising:

• an interface configured to receive an indication of a weight on a moveable support of a couch assembly, wherein the moveable support is moveable relative to a couch frame of the couch assembly;
• and
• at least one processor communicatively coupled to the interface and configured to execute a plurality of instructions to:
• receive the indication of the weight;
• receive an indication of an expected position for the moveable support to move to a modified position relative to the couch frame to provide the moveable support at a specified position relative to the imaging apparatus;
• and
• determine, for the expected position, a horizontal shift of the couch frame relative to an imaging apparatus associated with the couch assembly based on a shift model indicative of the horizontal shift as a function of:
• the weight on the moveable support;
• and
• a horizontal position of the moveable support relative to the couch frame.
