A gastroenteral tube positioning guidance system comprising: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; wherein said electromagnetic field generator is external to the subject; a registration sensor configured to mark at least three anatomic locations on the subject's torso, the anatomical locations comprising the xiphoid process and the left and right claviculae of the subject ; a gastroenteral tube comprising a tip sensor configured to be tracked within the treatment area relative to the electromagnetic field generator; a reference sensor configured to be positioned, within the treatment area, on the subject's torso, and to define the reference coordinate system representing the position and orientation of the subject's torso relative to said field generator ; and a processing circuitry configured to: calculate an orientation of the subject relative to the field generator based on a marking of the xiphoid process and a marking the left and right claviculae of the subject by the registration sensor ; derive from the marking of the left and right claviculae of the subject, a location corresponding to the suprasternal notch ; load a predefined anatomical map representing a torso; align the map based on the locations corresponding to the xiphoid process and the suprasternal notch, and show on the map a path of the gastroenteral tube insertion; wherein the path is generated according to changes in the strength of the electromagnetic field sensed by the tip sensor's during the insertion of the gastroenteral tube. an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; wherein said electromagnetic field generator is external to the subject; a registration sensor configured to mark at least three anatomic locations on the subject's torso, the anatomical locations comprising the xiphoid process and the left and right claviculae of the subject ; a gastroenteral tube comprising a tip sensor configured to be tracked within the treatment area relative to the electromagnetic field generator; a reference sensor configured to be positioned, within the treatment area, on the subject's torso, and to define the reference coordinate system representing the position and orientation of the subject's torso relative to said field generator ; and a processing circuitry configured to: calculate an orientation of the subject relative to the field generator based on a marking of the xiphoid process and a marking the left and right claviculae of the subject by the registration sensor ; derive from the marking of the left and right claviculae of the subject, a location corresponding to the suprasternal notch ; load a predefined anatomical map representing a torso; align the map based on the locations corresponding to the xiphoid process and the suprasternal notch, and show on the map a path of the gastroenteral tube insertion; wherein the path is generated according to changes in the strength of the electromagnetic field sensed by the tip sensor's during the insertion of the gastroenteral tube. calculate an orientation of the subject relative to the field generator based on a marking of the xiphoid process and a marking the left and right claviculae of the subject by the registration sensor ; derive from the marking of the left and right claviculae of the subject, a location corresponding to the suprasternal notch ; load a predefined anatomical map representing a torso; align the map based on the locations corresponding to the xiphoid process and the suprasternal notch, and show on the map a path of the gastroenteral tube insertion; wherein the path is generated according to changes in the strength of the electromagnetic field sensed by the tip sensor's during the insertion of the gastroenteral tube. <EOS>
