摘要： A virtual beam's-eye view of a planning target volume is generated based on volumetric image data acquired immediately prior to radiation therapy by a radiation therapy system. The virtual beam's-eye view can then be displayed to confirm that, with the patient disposed in the current position, the planned beam-delivered treatment extends beyond the surface of the skin. In some embodiments, the virtual beam's-eye view can be displayed in conjunction with a beam's-eye view that is generated based on volumetric image data acquired during treatment planning, to create a blended beam's-eye view. In some embodiments, a field outline of a treatment beam can be superimposed on the blended beam's-eye view, thereby illustrating whether the planned beam-delivered treatment extends beyond the surface of the skin of the patient. The blended beam's-eye view can facilitate a manual confirmation process that verifies the planned beam-delivered treatment extends beyond the surface of the skin.

摘要： An optimal bicycle frame size based on operational characteristics provided by a rider when riding a dynamic fit unit is determined. A best-fit bicycle frame size that is a closest match to the optimal frame size is determined. At least one of the optimal X,Y location of the bicycle's handlebar relative to the bottom bracket, and the optimal X,Y location of the bicycle's seat relative to the bottom bracket, is determined. A stem and spacer from a list of available stems and spacers that will best fit between the head tube of the best-fit frame and the optimal X,Y location of the handlebar is determined. A seat post from a list of available seat posts that will best fit between the seat tube of the best-fit frame and the optimal X,Y location of the seat is determined. A list of the best-fit frame, the best fit stem and spacer, and the best fit seat post, is produced.

摘要： A radiotherapeutic apparatus comprises a source of therapeutic radiation, a source of visible light arranged to cast a light field corresponding to the beam of radiation, and a multileaf collimator for shaping the beams, wherein a filter is disposed in the path of the visible light beam having a plurality of linear dark sections corresponding to leaves of the collimator. This prevents the incident light from falling on the leaves and removes the ghost images at source. By placing the filter in the head, the line can be very narrow and will be blurred into penumbra at the isocentre. This is therefore a very inexpensive yet effective method of reducing ghosting. A mirror can deflect the path of the visible light to correspond to that of the radiation beam, and the filter can be disposed anywhere in the beam path, such as prior to the mirror, subsequent to the mirror and prior to the collimator, or subsequent to the collimator. The filter thus creates dark sections in the light field corresponding to leaves (preferably all the leaves) of the collimator.
摘要翻译：一种放射治疗装置包括治疗辐射源，布置成投射与辐射束对应的光场的可见光源，以及用于使束成形的多叶准直器，其中滤光器设置在可见光束的路径中具有对应于准直仪叶片的多个线性暗部分。这可以防止入射光落在叶子上，并从源头上去除幻像。通过将过滤器放置在头部中，线可以非常窄，并且会在等中心的半暗中模糊。因此，这是减少重影的非常便宜而有效的方法。反射镜可以使可见光的路径偏转以对应于辐射束的路径，并且滤光器可以设置在光束路径中的任何位置，例如在镜子之前，在镜子之后，在准直器之前，或之后到准直仪。因此，过滤器在光场中产生对应于准直器的叶（优选地是所有叶）的暗部分。

摘要： A portable orthovoltage radiotherapy system is described that is configured to deliver a therapeutic dose of radiation to a target structure in a patient. In some embodiments, inflammatory ocular disorders are treated, specifically macular degeneration. In some embodiments, the ocular structures are placed in a global coordinate system based on ocular imaging. In some embodiments, the ocular structures inside the global coordinate system lead to direction of an automated positioning system that is directed based on the ocular structures within the coordinate system.
