This is an automated needle
orientation method under fluoroscopy guidance. The physician selects
the target by succesivly pointing it in two lateral views diplayed
on the robot's controller screen. With the needle piont at the skin
entry point, the RCM performs a series of moves to determine the allignment
and finally orients the needle to the target. The physician inspects
targeting and performs needle insertion from the joystick under direct
fluoroscopic observation.
The method tested experimentally with 0.5 mm targeting
accuracy. The method applies to the RCM
and AcuBot
X-Ray guided systems.
