System and method for radio-frequency imaging, registration, and localization
First Claim
1. A system for performing a medical procedure with at least one instrument on a patient comprising:
- an imaging head defining a field of view relative to the patient, the imaging head including;
at least one radio-frequency transmitter that emits a least one signal in the field of view;
at least one radio-frequency receiver that receives a plurality of reflected radio frequency signals based on at least one electrical property of at least one material in the field of view and the at least one instrument;
a workstation having a control module that determines, based on the plurality of reflected radio frequency signals received by the at least one radio-frequency receiver, a location of at least one boundary of the at least one material within the field of view and a location of the at least one instrument in relation to the patient in the field of view;
wherein the workstation is configured to determine a type of material associated with the at least one instrument based upon the reflected radio frequency signals associated with the at least one instrument and a signal produced by the at least one radio-frequency transmitter; and
a display that displays an image of the location of the at least one boundary, and renders an icon of the at least one instrument on the image.

Abstract
A system for performing a medical procedure on a patient is provided. The system can include an imaging head defining a field of view relative to the patient. The imaging head can include at least one transmitter that emits at least one signal in the field of view, and at least one receiver that receives at least one reflected signal from the field of view. The at least one reflected signal received can be based on at least one electrical property of at least one material in the field of view. The system can further include a workstation, which can determine, based on the at least one reflected signal received by the at least one receiver, a location of at least one boundary of the material within the field of view. The system can include a display that displays an image of the location of the at least one boundary.

13. A system for performing a medical procedure on a patient comprising:
-
at least one tracking device; a tracking system that tracks the at least one tracking device; an imaging head having an imaging system that transmits at least one imaging radio-frequency signal within a field of view and receives at least one reflected imaging radio-frequency signal within the field of view for forming an image, the imaging head having at least one transmitter that emits the at least one imaging radio-frequency signal in the field of view, wherein the imaging head has at least one receiver that receives the at least one reflected imaging radio-frequency signal; and a navigation system that determines, based on the tracking of the tracking device and RF image data formed from the at least one reflected imaging radio-frequency signal, a location of the imaging head, the at least one tracking device and the patient during registration and navigation, within the field of view. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for performing a medical procedure on a patient comprising:
-
positioning at least one imaging head relative to a patient to define a field of view; positioning at least one surgical instrument relative to a patient in the field of view; emitting at least one radio-frequency signal from the imaging head into the field of view; receiving a plurality of reflected radio-frequency signals from the field of view with the imaging head; determining, based on the plurality of reflected radio-frequency signals received from the field of view, at least one electrical property associated with at least one material and the at least one instrument within the field of view; determining, based on the at least one electrical property and the plurality of reflected radio-frequency signals received from the field of view, a location of a boundary associated with the at least one material within the field of view and the location of the at least one surgical instrument; and determining a type of instrument associated with the at least one instrument based upon a material associated with the at least one instrument and the plurality of reflected radio-frequency signals. - View Dependent Claims (25, 26, 27, 28, 29, 30)
