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.

Imaging systems and methods for image-guided radiosurgery

Therapeutic radiation beam detector for radiation treatment systems

Devices, systems and method that allow for delivery of therapeutic radiation beams of differing sizes or shapes during a radiation treatment are provided herein. Such devices can include a rotatable collimator body having multiple collimator channels of differing size or shape defined therein, the channels extending through the collimator body substantially perpendicular to the axis of rotation. The collimator body can include markers thereon to facilitate detection of an alignment position by a sensor of a control system to allow the collimator body to be rapidly and accurately moved between alignment positions to facilitate delivery of differing therapy beams during a treatment.
