摘要：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.

主权项：1. An apparatus, comprising: a needle positioning device configured to position a needle guide at a fixed target location with respect to a patient disposed on a movable cradle of an imaging system such that a needle can be inserted through an opening defined by the needle guide and moved relative to the needle guide, through an insertion point on the patient and within a target point within the patient; and processing circuitry configured to: receive images of the patient from the imaging system;determine, based at least in part on the received images, a location of the insertion point relative to a gantry of the imaging system in which a needle is to be inserted into the patient when the patient is disposed on the movable cradle; anddetermine a directional vector between the insertion point and the target point within the patient, the fixed target location of the needle guide to be in line with the directional vector based at least in part on the determined location of the insertion point and the directional vector.
