Abstract
Apparatus for accurate positioning of a needle guide is disclosed. The apparatus provides a means for taking as input the position vector for the point of insertion of the needle into the body. This point of insertion can be selected from images produced by a Computer Tomography system. Similarly, the apparatus has a means for taking as input the point of target. A controller determines the directional vector between point of insertion and point of target. A guide manipulator accurately positions the needle guide in line with the directional vector, such that the needle can easily be inserted through the guide to the point of target. The positioning of the guide manipulator in accordance with the directional vector is done with the help of motors.
