Abstract
An apparatus and method for performing treatment on an internal target region while compensating for breathing and other motion of the patient is provided in which the apparatus comprises a first imaging device for periodically generating positional data about the internal target region and a second imaging device for continuously generating positional data about one or more external markers attached to the patient's body or any external sensor such as a device for measuring air flow. The apparatus further comprises a processor that receives the positional data about the internal target region and the external markers in order to generate a correspondence between the position of the internal target region and the external markers and a treatment device that directs the treatment towards the position of the target region of the patient based on the positional data of the external markers.
