1. A guidance system for guiding insertion of a pediatric feeding tube into a pediatric patient, comprising:
an electromagnetic field generator configured to be positioned externally to the patient's torso, the electromagnetic field generator configured to generate an electromagnetic field covering a treatment area on the patient's torso;
a pediatric feeding tube comprising a sensor assembly removably positioned therein, the sensor assembly comprising an electromagnetic sensor at a distal tip thereof; wherein an outer diameter of the pediatric feeding tube is 2 mm or less;
a registration sensor configured to mark at least a first and a second anatomic location relative to the reference coordinate system; and
a processing circuitry configured to:
operate said field generator,
read signals obtained from the registration sensor,
generate and/or display a 3D anatomic map representing the torso of the subject and the first anatomic location and a second anatomic location, and
visualize, on the 3D anatomic map, a position and/or path of the enteral tube with respect to the first and second anatomic locations.
