Abstract
The invention comprises an integrated skin-mountable multifunction device for use with a computer assisted or image guided surgical system and methods of using the same, wherein the multifunction device includes a patient mountable portion that has at least one position indicating element and at least one imageable pattern whose geometry is known in a coordinate system of the at least one position indicating element, wherein the imageable pattern is visible on an imaging modality. The multifunction device may also include a monitoring device capable of measuring a physiological parameter of a patient for use in gating image or position signals or for other purposes.

13. An integrated skin-mountable multifunction device for use with an image guided surgical system, the device comprising:
-
a patient mountable portion comprising a base layer and a cover layer, wherein the base layer is removably attachable to a skin surface of a patient;
a circuit board attached to the patient mountable portion having at least one position indicating element attached thereto; and
at least one imageable pattern attached to the patient mountable portion whose geometry is known in a coordinate system of the at least one position indicating element, wherein the at least one imageable pattern is visible via an imaging modality.

14. A method for imaging a surgical instrument within a patient during a surgical intervention performed on the patient using a multifunction device, wherein the surgical instrument is equipped with one or more surgical position indicating elements, wherein the multifunction device includes one or more imageable patterns and one or more external position indicating elements, wherein the position and orientation of the surgical and external position indicating elements may be obtained using a tracking device, the method comprising:
-
placing the multifunction device onto the patient;
obtaining one or more images of the patient, wherein the one or more imageable patterns are visible on the one or more images;
receiving image-space data regarding the geometry of the one or more imageable patterns in the coordinate system of the one or more images;
receiving patient-space data regarding position information of the one or more external position indicating elements in the coordinate system of the tracking device;
registering the patient-space data in the coordinate system of the tracking device to the image-space data in the coordinate system of the images; and
measuring at least one physiological parameter of the patient using the multifunction device, displaying the location of the one or more surgical position indicating elements on the one or more images relative to the location of the one or more external position indicating elements, wherein the display is gated by the at least one physiological parameter. - View Dependent Claims (15, 16)
