Abstract

There is provided herein a guidance system for positioning an insertion device comprising: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area, an insertion device comprising an electromagnetic sensor, the electromagnetic sensor configured to receive signals indicative of the electromagnetic field, and a processing circuitry configured to: load an X-ray, CT, ultrasound or MRI image of the subject's chest, mark a location of a first and a second anatomic landmarks on the subject's torso using a registration sensor and obtaining a subject coordinate system based thereon, identify the location of the first and the second anatomic landmarks on the loaded X-ray, CT, ultrasound or MRI image of the subject's chest; aligning the subject coordinate system with the loaded X-ray, CT, ultrasound or MRI image, and display, on the image, a path of the insertion device insertion with respect to the first and the second anatomic locations; 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 insertion device.

Abstract

There is provided herein a system and a method for an insertion device positioning guidance system comprising: an electromagnetic field generator configured to generate an electromagnetic field covering a treatment area; a reference sensor configured to be positioned, within the treatment area, on the subject's torso, the reference sensor is configured to define a reference coordinate system representing the position and orientation of the subject's torso relative to the field generator; a registration sensor configured to mark at least a first and a second anatomic locations relative to the reference coordinate system; and a processor configured to operate the field generator, read signals obtained from the reference sensor and the registration sensor, calculate a position and orientation thereof relative to the field generator, generate a 3D anatomic map representing the torso of the subject and the first and second anatomic locations, the processor is further configured to facilitate visualization on the 3D anatomic map of a position, orientation and/or path of a tip sensor, located in a distal tip section of the insertion device, with respect to the first and second anatomic locations, independent of the subject's movement and independent of deviations in the position and/or orientation of the field generator, thus determination of a successful medical procedure is facilitated.
