摘要： A property of a treatment beam is controlled during a scanning period. A portion of a region is exposed to an imaging x-ray beam during a scanning period, the imaging x-ray beam being generated by an electron-beam scanner. X-ray radiation from the region is detected, the x-ray radiation representing an attenuation of the imaging x-ray beam caused by the portion of the region. A first image of the portion of the region is generated based on the detected x-ray radiation. A characteristic of the portion of the region is determined from the generated first image. An input derived from the characteristic is generated, the input configured to cause a source of a treatment beam to modify a property of the treatment beam. The source of the treatment beam modifies a property of the treatment beam during the scanning period by providing the input to the source of the treatment beam.

摘要： A scanning electron beam computed tomographic system eliminates axial offset between target and detector by disposing the target, collimator, and detector such that active portions of the target and detector are always diametrically opposite each other. This result is achieved by providing a helical target, collimator, and detector, or by providing planar target, collimator, and detector components that are inclined relative to the vertical axis such that active portions of the target and detector are always diametrically opposite each other. Either configuration eliminates cone beam error and the necessity to correct for same. Further, the system can provide multi-slice scanning of an object that is in constant motion at a critical velocity, without having to interpolate data. Conventional helical scanning may still be undertaken. Detector elements can be disposed axially to improve signal/noise ratio and to produce a cone beam cancellation effect.
摘要翻译：扫描电子束计算机断层摄影系统通过设置目标，准直仪和检测器来消除目标和检测器之间的轴向偏移，使得目标和检测器的有效部分总是沿径向相反。该结果通过提供螺旋靶，准直器和检测器，或者通过提供相对于垂直轴线倾斜的平面靶，准直器和检测器部件来实现，使得靶和检测器的有效部分总是沿直径相对。任何一种配置都可以消除锥形光束误差，同时也需要进行校正。此外，该系统可以以临界速度提供恒定运动的物体的多层扫描，而无需内插数据。传统的螺旋扫描可能仍然可以进行。检测器元件可以轴向布置以改善信号/噪声比并产生锥形束消除效果。

摘要： A tomogram is obtained by tomosynthesis in a high speed CT scanning system in which fan beams of radiation are generated by sweeping an electron beam along a target, and collimated X-rays emitted by the target are received by an array of detectors after passing through a patient area between the target and array of detectors. The patient is moved through the collimated x-rays as the measurments are obtained, and the measurements are time-correlated to correspond to data measurements for a plurality of projection radiographs. The measurements for the plurality of radiographs are combined to tomosynthesize a tomogram at a selected plane in the patient.
