SYSTEM AND METHOD FOR GUIDING THE MOVEMENTS OF A DEVICE TO A TARGET PARTICULARLY FOR MEDICAL APPLICATIONS

摘要

A system and method for guiding the movements of a device (2) to a target (4) particularly for medical applications is provided. In one aspect of the invention, the system guides the movements of a device (2) toward a target (4), which is viewable from an image. The system includes at least one scanning apparatus (5) for creating the image including the target (4), at least one transmitter 10 at a first reference location for transmitting radiant energy from the reference location, several position sensors (8, 9) and a data processor (6). The position sensors (8, 9) include at least one position sensor (8) on the device (2) for receiving the radiant energy, at least one position sensor (9) on the scanning apparatus (5) for receiving the radiant energy and at least one position sensor (8, 9) for receiving the radiant energy on either the device (2) or the scanning apparatus (5). The data processor (6) is in operative communication with the transmitter (10) and each of the position sensors (8, 9), for monitoring the accuracy of the calculated position of the device (2) with respect to the scanning apparatus (5).
