This method mimics the joystick controlled superimposed needle targeting method performed by the physician. The fluoro-image is fed to the computer of the robot which automatically orients the needle using the image feedback using a fluoro-servoing algorithm.

automated needle targeting

The method was experimentally tested and compared to the joystick method. Accuracy results showed 0.8 mm automatic vs. 1.03 mm with the joystick and access times of 5.54 s vs. 10.56 s, respectively. The method applies to the RCM and AcuBot X-Ray guided systems.
