Injection training apparatus using 3d position sensor

Abstract

Systems and methods are disclosed for an apparatus and method for practicing injection techniques through an injectable apparatus. The injectable apparatus may contain a camera that is configured to provide three-dimensional location information for a testing tool based on light attenuated from the testing tool after it is injected into a simulated human or animal body parts. A training tool may be connected to a user display device to generate a display of the injection apparatus as well as the performance parameters of a trainee.

         23 . A method of three-dimensional (3D) injection training, the method comprising:
 calibrating at least one of a light source in a testing tool and a three-dimensional tracking system, the testing tool being configured to simulate an injection;   detecting, by the three-dimensional tracking system, a characteristic of light emitted from the light source during the simulated injection; and   generating three-dimensional location information of the light source based on the detected characteristic and said calibrating.   
     
     
         24 . The method of  claim 23 , wherein said calibrating comprises obtaining calibration information from a memory. 
     
     
         25 . The method of  claim 24 , wherein said calibrating comprises:
 receiving, at the three-dimensional tracking system, light from the light source from a predetermined location;   generating calibration information; and   storing said calibration information in a memory.   
     
     
         26 . The method of  claim 23 , wherein said detecting comprises receiving a plurality of measurements from an array of light sensors included in the three-dimensional tracking system. 
     
     
         27 . The method of  claim 26 , wherein said detecting is based on which sensors in the array of sensors received measurable light. 
     
     
         28 . The method of  claim 23 , wherein said characteristic of the light emitted comprises intensity, angle, dispersion, brightness, color, or duration of the light. 
     
     
         29 . The method of  claim 23 , further comprising:
 obtaining a three-dimensional model of a site for the injection; and   generating an injection training result based on the location information for the light and the three-dimensional model of the site.   
     
     
         30 . The method of  claim 29 , wherein the injection training results includes an animated depiction of the injection at the site. 
     
     
         31 . The method of  claim 30 , further comprising receiving a display point of view, the display point of view identifying a virtual location in space from which to view the animated depiction, and wherein said generating the injection training result is further based on the display point of view. 
     
     
         32 . The method of  claim 29 , further comprising detecting a plurality of locations for the injection over time, and wherein said generating the injection training result includes generating a trajectory path for the injection.
