摘要： An X-ray optical alignment system for X-ray imaging devices includes a visible-light point source and a multi-axis positioner therefor, fixedly mounted with respect to the X-ray focal spot. A mirror or beamsplitter is fixedly mounted with respect to the X-ray focal spot and disposed in the beam path of the X-ray source. The beamsplitter reflects light emitted from the light source and transmits X-rays emitted from the X-ray source. A first X-ray attenuating grid is fixedly but removably mountable with respect to the X-ray source, having a first X-ray attenuation pattern; and a second X-ray attenuating grid is adjustably mountable with respect to the first grid having a second X-ray attenuating pattern corresponding to the first X-ray attenuating pattern. When the grids are aligned, their attenuating patterns are also aligned and allow X-rays from the X-ray source and light reflected from the beamsplitter to pass therethrough.

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 first laser device and a second laser device direct a laser beam towards a patient before a CT scan to visually indicate an outer boundary of an area where x-rays will be directed during the CT scan. Each laser device includes a prism that deflects the laser beams to form lines on the patient that define an outer boundary of an area of the patient that will be exposed to the x-rays. If the area of the patient between the lines is not the desired area, the operator can move the patient until the desired area of the patient is located between the lines. A third laser device can direct a laser beam to define an outer boundary that is used to ensure proper orientation of the patient in the space.

摘要： An apparatus and method for optimally positioning a region of interest of a subject for imaging by a CT scanner. The scanner provides a source of one or more X-ray beams, at least one of which is used for acquiring a CT image of the subject, a movable support for the subject, and a controller that controls the X-ray source. To position the region of interest of the subject, the controller operates to illuminate the subject with X-rays to acquire stereo image data for the region of interest and controls the position of the support responsive to the stereo image data.
