Abstract
Some medical procedures may be assisted by an electromagnetic fiducial element assembly that is affixed to the body of a patient. The electromagnetic fiducial element assembly has a flexible substrate and an affixation mechanism such as an adhesive arranged to removably affix the electromagnetic fiducial element assembly to the body of a patient. The assembly also includes a housing coupled to the flexible substrate that partially or fully contains a first trackable electromagnetic element. A medically imagable structure is integrated with the electromagnetic fiducial element assembly. In the medical procedures, a medical image of a portion of the patient's body is captured, and a representation of the medically imagable structure is visually apparent in the medical image. When a medical device having a second trackable electromagnetic element is advanced into the body of the patient, the medical device, the first and second trackable electromagnetic elements are tracked with a sensor device and an image representing the medical device is formed in the captured medical image.
