Methods and systems for adjusting subject table behaviors

A method for controlling a manually driven subject table, comprising:

• receiving a user input to the manually driven subject table;
• receiving a strength and a direction of a magnetic field detected in real-time using a passive sensor implemented in a manually driven subject table;
• accessing a field map representing a spatial distribution of the magnetic field and identifying a position and an orientation of the manually driven subject table based on the strength and the direction, respectively, of the magnetic field;
• and
• augmenting transmission of the user input to one or more actuators of the manually driven subject table based on the position and the orientation of the manually driven subject table.

A medical imaging system, comprising:

• a magnet configured to selectively generate a magnetic field;
• a manually driven subject table having at least one passive sensor configured to detect in real-time a strength and/or a direction of the magnetic field, one or more undriven wheels, a drive wheel, a docking system, a table control panel (TCP), and a controller communicably coupled to the passive sensor and configured with instructions stored on non-transitory memory that, when executed, cause the controller to:
• compare the strength and/or the direction of the magnetic field identified by the passive sensor to a field map representing a spatial distribution of the magnetic field to identify a position and an orientation, respectively, of the manually driven subject table with respect to the magnet;
• determine a desired behavior of the manually driven subject table based on the position and the orientation of the manually driven subject table;
• and
• add, remove, and/or augment operating parameters of the manually driven subject table to augment transmission of a user input received by the controller to one or more actuators of the manually driven subject table based on the strength or the direction of the magnetic field as detected by the passive sensor.
