Abstract: A method and apparatus for positioning a patient for radiation treatment are described. The method includes obtaining a plurality of projection images of a patient positioned on a treatment couch, displaying at least one of the plurality of projection images with a corresponding synthetic projection image on a display, adjusting the position of the at least one projection image on the display to approximately align with the corresponding synthetic projection image in response to a user dragging the at least one projection image on the display with a user interface device, and moving the treatment couch to position the patient based on position adjustments of the at least one projection image.

Abstract: An image guided treatment is performed to treat a target. To perform the image guided treatment, measurement data indicative of target motion is acquired. A timing of one or more x-ray images is determined based on the measurement data. Treatment may be performed on the target using the position of the target.

Abstract: A treatment delivery system or a simulation system simulates treatment of a patient, including testing the ability of one or more tracking methods to track a target position during the simulation. The system then presents simulation results to a user, the simulation results indicating whether any of the one or more tracking methods will successfully track the target position during treatment delivery.

Abstract: A patient positioning assembly for therapeutic radiation treatment includes a support device for supporting the patient during treatment, and a controller for controlling the motion of the support device so that the treatment target within the patient is properly aligned with respect to a radiosurgical treatment apparatus throughout the treatment. The controller generates motion command signals for implementing corrective motions of the support device. The corrective motions align the target so that the position and orientation of the target, as shown in near real time image data, substantially match the position and orientation of the target, as shown in pre-treatment scans. One or more user interface modules, for example a handheld remote control module and a user interface screen, allows the user to interactively control the motion of the support device, by implementing one or more user selectable functions.
