Abstract
An imaging positioning system having a robotically positioned support structure is provided. By utilizing a robotic arm, imaging along multiple planes within a patient treatment room without having to move the patient is provided. Such a configuration allows multiple axis x-ray imaging, cone beam CT acquisitions having a dynamic field of view, and PET imaging within the treatment room. Rotation of the imaging panel on the support structure allows the imaging system to simulate a gantry rotation when a fixed beam is used for treatment. Beam line x-ray imaging is also provided by tilting the imaging panel or by moving the support structure on which the x-ray source is positioned. Laser distance scanning for collision avoidance and force torque sensing movement enhance the safety thereof. The support structure may be in the form of a ring along which the imaging components may move.
