Localization of a radioactive source within a body of a subject

Abstract

A system and method is provided for determining a route to a target. The system can include a display device, where the display device can be operable to display a graphical representation of a 3 dimensional model of a portion of a vasculature of a body. Further, the display device can be operable to allow a user to select a target location on the 3 dimensional model. Further still, the display device can be operable to automatically determine an intravascular route to the target location using the 3-dimensional model, or it can be operable to allow the user to manually determine an intravascular route to the target location using the graphical representation of the 3-dimensional model.

         34 . A method of determining a route to a target comprising:
 displaying a graphical representation of a 3-dimensional model of a portion of a vasculature;
 wherein the portion of the vasculature is located within a region of a body; 
   selecting a target location on the 3-dimensional model; and   determining an intravascular route to the target location using at least one of: the 3-dimensional model and the graphical representation of the 3-dimensional model;   wherein determining the intravascular route is performed at least one of: automatically and manually.   
     
     
         35 . The method of  claim 34 , wherein the 3-dimensional model of the portion of the vasculature is generated, at least in part, from a 3-dimensional image dataset of the region of the body. 
     
     
         36 . The method of  claim 35 , wherein the 3-dimensional image dataset is at least one of: a CT image dataset, an MRI image dataset, and a fluoroscopy 3D angiography image dataset. 
     
     
         37 . A system for determining a route to a target, the system comprising:
 a display device;   wherein the display device is operable to display a graphical representation of a 3-dimensional model of a portion of a vasculature of a body;   wherein the display device is operable to allow a user to select a target location on the 3-dimensional model;   wherein the display device is at least one of:
 operable to automatically determine an intravascular route to the target location using the 3-dimensional model; and 
 operable to allow the user to manually determine an intravascular route to the target location using the graphical representation of the 3-dimensional model.
