Abstract: 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.

Abstract: The invention relates to a method for determining the position of an object moving within a body, wherein the body is connected to markers, a movement signal is determined based on the measured movement of the markers, images are taken from the object using a camera or detector, wherein the camera or detector is moved with respect to the object, it is determined from which direction or range of angles or segment the most images corresponding to a predefined cycle of the movement signal are taken, and using at least some or all of the images of the segment containing the most images for a specified movement cycle, an image of the object is reconstructed.

Abstract: The present invention relates to a determination method that enables the position of a body part subject to vital movement to be determined, wherein the body part is to be irradiated. A region of an analytical image is determined, wherein the region represents a body part subject to vital movement, in particular a tumor in an anatomical body. A change in position from one analytical image to the next is performed that reflects the vital movement, wherein the body parts subject to vital movement are parts of the body that are to be irradiated or are not to be irradiated and that move as a result of vital functions such as respiration and/or heartbeat even when the anatomical body is otherwise kept deliberately at rest.

Abstract: An imaging apparatus for irradiating an object includes a source arrangement, from which x-rays from different positions that form an at least one-dimensional structure may be emitted. The imaging apparatus also includes a detector arrangement for detecting the x-rays. An object is positioned between the source arrangement and the detector arrangement so that, with the detector arrangement, the x-rays attenuated by the object are recorded. The imaging apparatus also includes an evaluation apparatus for evaluating the signals recorded by the detector arrangement. A region of the detector arrangement is assigned to different positions of the structure, from which x-rays are directed at the region in partial irradiations. The region is aligned relative to the structure, such that the partial irradiations that are produced from the different positions of the structure with a region of the detector develop a radiation geometry that irradiates the object in a planar fashion.
