METHODS AND SYSTEMS FOR PERFORMING NAVIGATION-ASSISTED MEDICAL PROCEDURES
First Claim
1. A method of performing navigation-assisted medical procedures comprising:
- estimating location information of an item of interest located within at least a portion of a subject using an algorithmic deformation model based on acquired image information to estimate unobserved motion of the item of interest within at least the portion of the subject;
sensing position information of a moveable device;
determining a relative position of the moveable device to the item of interest using the estimated location information of the item of interest and the position information of the moveable device; and
providing directional and distance active feedback based on the relative position of the moveable device to the item of interest that can be used to change the relative position of the moveable device to the item of interest during a navigation-assisted medical procedure, wherein the active feedback changes as the moveable device moves closer to or further away from the item of interest, and wherein the distance active feedback comprises distance encoded vibration frequencies provided through the moveable device.

Abstract
Systems and methods are described for performing navigation-assisted medical procedures such as biopsies, surgeries and pathology procedures by obtaining location information of an item of interest located within at least a portion of a subject; sensing position information of a moveable device; determining a relative position of the moveable device to the item of interest using the location information of the item of interest and the position information of the moveable device; and providing feedback based on the relative position of the moveable device to the item of interest that can be used to change the relative position of the moveable device to the item of interest.
