Assistance system for needle-based procedures

At RSNA in Chicago Fraunhofer IPA and MEVIS present an assistance system for needle-based procedures. It consists of a robot with multiple tools including one for registration to the imaging system and a software program for planning the procedure. The workflow that we are aiming for is as follows:
• Place the robot holding the registration tool in the imaging volume with the patient.
• Take a 3D scan of the patient
• (Automatically) register the robot to the imaging system by identifying the tool geometry in the image
• When needed, map the interventional image to a diagnostic data set
• Select where to insert the needle and the target and send these coordinates to the robot
• The robot moves into position and the needle can be inserted through needle guide held by the robot

The combination of the planning software and the robot execution ensures that the desired precision is achieved. It also speeds up the needle placement after the planning, because the robot can reach the correct position and orientation within seconds. A thorough understanding of the robot capabilities and application programming and has ensured this successful integration of planning software and robot hardware.

At RSNA Chicago, November 29 – December 4, we will present the planning software and demonstrate how the robot executes its positioning task when given a specific target.
