A self-shielded and computer controlled system for performing non-invasive stereotactic radiosurgery and precision radiotherapy using a linear accelerator mounted within a two degree-of-freedom radiation shield coupled to a three-degree of freedom patient table is provided. The radiation shield can include an axial shield rotatable about an axial axis and an oblique shield independently rotatable about an oblique axis, thereby providing improved range of trajectories of the therapeutic and diagnostic radiation beams. Such shields can be balanced about their respective axes of rotation and about a common support structure to facilitate ease of movement. Such systems can further include an imaging system to accurately deliver radiation to the treatment target and automatically make corrections needed to maintain the anatomical target at the system isocenter. Various subsystems to automate controlled and coordinated movement of the movable shield components and operation of the treatment related subsystems to optimize performance and ensure safety are also provided.

A method of real-time radiotherapy beam visualization is provided that includes disposing a free-form flexible scintillating sheet on a subject of interest, irradiating the subject of interest with a source of ionizing radiation, where the free-forming flexible scintillating sheet emits light when irradiated by the therapeutic photon beam, collecting the emitted light and collecting ambient light reflected from the subject of interest and surrounding objects using a camera, where the collected light is converted to image data by the camera, where the image data is communicated to an appropriately programmed computer, and processing the image data to determine beam characteristics and the characteristics of the subject of interest, using the appropriately programmed computer, where the beam characteristics and the characteristics of the subject of interest are displayed in real-time to a machine operator enabling real-time verification of treatment delivery.
