摘要： A collimator for a radiotherapy apparatus, comprising a block of isolation-attenuating material having a front face forming the leading edge of tie block and at least one main rear face defining the trailing edge of the block, in which the or each rear face is substantially planar in the direction of the depth of the block and non-parallel to the front face. The collimator may form part of a radiotherapy apparatus, and methods of operation of such apparatus are described.

摘要： A system or use with a radiotherapy system includes a scanner for producing images of at least one object within an imaging volume, a radiotherapy apparatus including a source of therapeutic radiation adapted to deliver a beam of radiation into the at least one object, a treatment planning system for controlling the source so as to deliver radiation in accordance with a predetermined plan for treating a patient and with the images of the at least one object, and at least one device within and/or adjacent to the imaging volume. The at least one device comprises at least one first marker which is visible to the scanner and at least one MR second marker which is visible to an MR scanner. The system further comprises a database containing data including the markers associated with the at least one device and at least its geometric and density characteristics.

摘要： Embodiments of the present invention provide markers, phantoms, and associated methods of calibration which are suitable for use in both magnetic resonance imaging and radiographic imaging systems. A marker includes a first marker component having a first hydrogen proton density and a first mass density; and a second marker component having a second hydrogen proton density different than the first hydrogen proton density, and a second mass density different than the first mass density. The first marker component and the second marker component are non-magnetic.

摘要： A method of aligning the radiation beam in a radiotherapy system comprising a source for producing a beam of radiation and an imaging device for imaging from the beam, both mounted to be rotatable about an axis, a fiducial phantom between the source and imaging device, the method comprising: rotating the beam and imaging device in a trajectory about the axis while obtaining images of the fiducial phantom from a plurality of different angles, at least one image including a feature of the imaging apparatus, adjusting the trajectory of the source relative to that feature to position the isocenter substantially in the center of the volume, determining from each image of the fiducial phantom the position of the source at the rotational position the image was obtained, and calculating the center of rotation of the positions of the source to define the isocenter of the system.
