Abstract
An improved electromagnetic field generating antenna is compatible with fluoroscopic imaging and can be placed under, above or anywhere around the patient. The antenna includes one or more antenna elements laid out on a single or multi-layer PCB with current conducting metal traces used for creating electromagnetic fields for tracking sensors. An antenna enclosure is made with a polymer or other non-conductive material. The antenna does not have to be moved for allowing medical imaging during various procedures. An X-ray filter may be made out of similar sub-components as a full antenna assembly with the sole purpose of reducing the radiation dose to the patient during medical procedures without negatively affecting the image quality.
