Surgical planning system and navigation system

Abstract

The present disclosure is directed to a planning and navigation system. The planning system includes a memory configured to store a plurality of images and a controller configured to render the plurality of images in three dimensions, automatically segment the plurality of images to demarcate a target area, and automatically determine a treatment plan based on the target area. The navigation system includes an ultrasound device having a fiducial pattern that obtains an ultrasound image, a surgical device having a image capture device that captures an image of the fiducial pattern, and a controller that receives the ultrasound image and the fiducial image. The controller determines a position of the surgical device based on the fiducial image. The planning and navigation system also includes a controller that receives data from the planning system and the navigation system and a display configured to display the received information.

         18 . A planning and navigation system, comprising:
 a planning system including:
 a memory configured to store a plurality of images; and 
 a first controller configured to render the plurality of images in three dimensions, segment the plurality of images to demarcate a target area, and automatically determine a treatment plan based on the target area; and 
   a navigation system including:
 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. 
 
   
     
     
         19 . The planning and navigation system of  claim 18 , 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. 
     
     
         20 . The planning and navigation system of  claim 18 , 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. 
     
     
         21 . The planning and navigation system of  claim 20 , wherein the controller is further configured to cause the navigation system to display a trajectory of the surgical device with respect to the image. 
     
     
         22 . The planning and navigation system of  claim 21 , wherein the trajectory is determined based on the defined relative position and defined relative angle of the surgical device to the scan plane. 
     
     
         23 . The planning and navigation system of  claim 18 , wherein the controller is further configured to cause the navigation system to display a virtual ablation zone. 
     
     
         24 . The planning and navigation system of  claim 23 , wherein the controller is further configured to adjust an energy level to adjust the virtual ablation zone. 
     
     
         25 . The planning and navigation system of  claim 23 , wherein the controller is further configured to adjust an ablation time setting to adjust the virtual ablation zone. 
     
     
         26 . The planning and navigation system of  claim 18 , wherein the target is identified in a pre-operative image. 
     
     
         27 . The planning and navigation system of  claim 26 , wherein the controller is further configured to cause the navigation system to determine calculated properties of the target upon identification of the target. 
     
     
         28 . The planning and navigation system of  claim 27 , wherein the location of the target in the pre-operative image is recorded. 
     
     
         29 . The planning and navigation system of  claim 28 , wherein the controller is further configured to cause the navigation system to identify the surgical device based on the calculated properties of the target. 
     
     
         30 . The navigation system of  claim 29 , wherein the controller is further configured to cause the navigation system to determine power and time settings based on the calculated properties. 
     
     
         31 . The navigation system of  claim 30 , wherein the controller is further configured to cause the navigation system to display initial power and time settings. 
     
     
         32 . The planning and navigation system of  claim 18 , wherein the image of the target is an ultrasound image. 
     
     
         33 . The planning and navigation system of  claim 18 , wherein the image of the target is a CT image.
