Abstract
An electromagnetic tracking system including a patient support element and an electromagnetic field generator. The patient support element is superposed relative to the electromagnetic field generator, and the electromagnetic field generator is selectively moveable relative to the patient support element.
Claims40
An electromagnetic tracking system comprising:
- a patient support table having a longitudinal axis, a transverse axis, and a patient contact surface, the transverse axis of the patient support table being substantially perpendicular to the longitudinal axis of the patient support table;
- and
- an electromagnetic field generator operatively coupled to the patient support table, the electromagnetic field generator being selectively moveable along at least one of the longitudinal axis and the transverse axis of the patient support table, wherein the electromagnetic field generator has a lower surface and an upper surface, and wherein the electromagnetic field generator defines a central opening through the lower surface and the upper surface,
- wherein the patient contact surface of the patient support table is superposed relative to at least a portion of the electromagnetic field generator.
