20090207977 | Laser Aligned Image Guided Radiation Beam Verification Apparatus - A method and apparatus for verifying radiation beam alignment in an image guided stereotactic radiosurgery (SRS) delivery system such as the Cyberknife™. SRS systems such as the Cyberknife™ use a high-precision robotic manipulator with an image-guided system to deliver beams of radiation to a target for optimal clinical results. This radiation delivery system does not usually rotate around a fixed center of axis, therefore a set of pre-programmed positions (nodes) defined as a path is often configured into the system's software to allow proper radiation treatment. In order to achieve the accuracy of the image-guided SRS radiation delivery, these nodes must be calibrated regularly to verify that the radiation beam axis precisely passes through a certain reference point or alignment center with predefined angles. This invention achieves precise verification of radiation beam alignment with a radiation beam detection apparatus mounted on a gimbal assembly. The radiation beam detection apparatus houses an alignment fixture of varying geometric shape, such as a metallic ball or can be an array of radio-opaque markers positioned symmetrically at the gimbal assembly's common rotation center. The radiation detection apparatus comprises a radiation detector such as film and an alignment mirror, which are parallel to each other on opposite sides of the alignment fixture. The radiation detector is used to capture a radiographic image of the alignment fixture and the circular radiation field. The resulting image is analyzed to determine the eccentricity of the radiation field. If the radiation beam is perfectly aligned, the resulting exposure on the film will show a perfectly symmetrically superimposed circular radiation field and the image of the alignment fixture. This method is used to verify beam alignment for each pre-calibrated node and determine whether adjustment to node positions is required. | 08-20-2009 |

The adjustment is accomplished by means of a transformation of projection data, the projection data corresponding to the control element that is to be projected. The optical projection of the control element is based on the transformed projection data. Such an adjustment and transformation are made possible by determining the surface structure of the projection surface. The control system has an image processor both for determining the surface structure and for transforming the projection data. The control system additionally has a projector for optically projecting the control element and a control unit for controlling the medical device based on the first position of the projected control element. | 12-10-2015 |
