摘要： X-ray therapy EPI artifact reduction and control of imaging is provided. Scanning of images is synchronized with the pulse rate of the x-rays. The scanning period is longer than the pulse rate period, so artifacts are generated within the resulting images. Due to the synchronization, the pulse variation artifacts are aligned across multiple images. The synchronization and resulting alignment of linear artifacts allows for gain correction as a function of lines within the image. Such gain correction reduces or removes non-linearities associated with pulse rate variation.

摘要： A system includes substantial focus of radiation on a focal area, the focused radiation following a radiation path from a lens to the focal area, and projection of light on a surface so as to substantially indicate an intersection of the radiation path with the surface. In some aspects, the light projected on the surface substantially indicates a distance between the surface and the focal area.

摘要： A vehicle anti-theft system includes an engine control computer operable to control engine fueling in a normal mode of operation according to operator demand via an accelerator pedal, and a code interface module responsive to a predefined security code to set the engine control computer in a secure mode of operation. In the secure mode, two fuel enabling values in the engine fueling algorithm are altered. Specifically, an engine startup enable value is altered so that the engine control computer disables fueling if the engine is not running, to thereby prevent an unauthorized individual from starting the engine. Likewise, an accelerator enable value is altered so that the engine control computer disregards the accelerator signal and controls fueling of the engine to thereby maintain an engine idling condition. The control computer is reset to its normal fueling control mode by re-entering the security code.
摘要翻译：车辆防盗系统包括发动机控制计算机，其可操作以根据操作者的需求通过加速器踏板来控制正常操作模式下的发动机燃料供应;以及代码接口模块，其响应于预定义的安全代码将发动机控制计算机设置在安全的操作模式。在安全模式下，改变发动机加油算法中的两个燃料使能值。具体地说，改变发动机启动使能值，使得发动机控制计算机在发动机不运转时禁止加油，从而防止未授权的个人起动发动机。同样地，加速器启用值被改变，使得发动机控制计算机忽视加速器信号并且控制发动机的燃料供应，从而保持发动机空转状态。通过重新输入安全码，控制计算机将重新设置为正常的加油控制模式。

摘要： A system includes determination of a treatment plan for delivering convergent radiation to a target based at least on a decrease in intensity of the convergent radiation due to material intercepted by the convergent radiation prior to reaching the target and on an increase in intensity of the convergent radiation due to a geometry of the convergent radiation. Some aspects include determination of a dose enhancement at the target over time due to contrast agent located at the target, wherein the determination of the treatment plan is based at least on the dose enhancement over time.

摘要： A device for linearly oscillating one or more of a plurality of X-ray filter elements singly or in combination in and out of an X-ray beam at television frame rates. First and second substantially coplanar filter elements are adjacent each other and formed as a unitary member that is transverse to the X-ray beam. It is slidable bidirectionally on parallel guide tracks in one plane. A servo motor drives a closed loop belt which attaches to said member. A third planar filter element runs on tracks in a plane parallel to that of the unitary member. There are lug means on the third element spaced apart in the direction of its travel member that project up and are between the lug means on the third element to enable pushing or pulling it. Thus, the first and second filter elements can be oscillated alternately in and out of the X-ray beam by moving said unitary member without engaging the third element so it stays out of the beam. The member can be driven to one travel limit to pull the third element into the beam and let it stay there while the first element is oscillated beneath it so the beam passes through two filters. And the member can be driven to one travel limit and not be oscillated so the third filter element stays in the beam.
