Surgical Navigation System

Abstract

The present disclosure is directed to a surgical navigation system. The navigation system includes an ultrasound device configured to obtain an ultrasound image in a scan plane The ultrasound device has a fiducial pattern disposed thereon. A surgical device having an image capture device configured to capture a fiducial image of the fiducial pattern is also provided. The system also includes a controller configured to receive the ultrasound image and the fiducial image, wherein the controller determines a position of the surgical device in relation to the scan plane based on the fiducial image. A display is configured to display the ultrasound image and a virtual image of the surgical device based on the position of the surgical device in relation to the scan plane.

1 - 8 . (canceled) 
     
     
         9 . A navigation system, comprising:
 an electromagnetic field generator configured to generate an electromagnetic field;   a surgical device;   an image capture device configured to obtain an image of a target;   a display; and   a controller configured to cause the navigation system to:
 generate the electromagnetic field; 
 detect a location of the surgical device in the electromagnetic field; 
 obtain the image of the target, the image defining a scan plane; 
 determine a spatial relationship between the surgical device and the scan plane; and 
 display a representation of the surgical device with respect to the target in the scan plane. 
   
     
     
         10 . The navigation system of  claim 9 , wherein the controller is further configured to cause the navigation system to display a position of the surgical device in relation to the scan plane. 
     
     
         11 . The navigation system of  claim 9 , wherein the spatial relationship between the surgical device and the scan plane defines a relative position and a relative angle of the surgical device to the scan plane. 
     
     
         12 . The navigation system of  claim 11 , wherein the controller is further configured to cause the navigation system to display a trajectory of the surgical device with respect to the image. 
     
     
         13 . The navigation system of  claim 12 , wherein the trajectory is determined based on the defined relative position and defined relative angle of the surgical device to the scan plane. 
     
     
         14 . The navigation system of  claim 9 , wherein the controller is further configured to cause the navigation system to display a virtual ablation zone. 
     
     
         15 . The navigation system of  claim 14 , wherein the controller is further configured to adjust an energy level to adjust the virtual ablation zone. 
     
     
         16 . The navigation system of  claim 14 , wherein the controller is further configured to adjust an ablation time setting to adjust the virtual ablation zone. 
     
     
         17 . The navigation system of  claim 9 , wherein the target is identified in a pre-operative image. 
     
     
         18 . The navigation system of  claim 17 , wherein the controller is further configured to cause the navigation system to determine calculated properties of the target upon identification of the target. 
     
     
         19 . The navigation system of  claim 18 , wherein the location of the target in the pre-operative image is recorded. 
     
     
         20 . The navigation system of  claim 19 , wherein the controller is further configured to cause the navigation system to identify the surgical device based on the calculated properties of the target. 
     
     
         21 . The navigation system of  claim 19 , wherein the controller is further configured to cause the navigation system to determine power and time settings based on the calculated properties. 
     
     
         22 . The navigation system of  claim 21 , wherein the controller is further configured to cause the navigation system to display initial power and time settings. 
     
     
         23 . The navigation system of  claim 9 , wherein the image of the target is an ultrasound image. 
     
     
         24 . The navigation system of  claim 9 , wherein the image of the target is a CT image.
