    • An X-Ray matrix imager includes a matrix, a plurality of gate line sets, and a plurality of data lines. The matrix includes a plurality of rows of pixels configured to accumulate charges in response to light or radiation. Each of the gate line sets includes a first gate line coupled to a first pixel among a first row of pixels of the matrix, and a second gate line coupled to a second pixel among the first row of pixels of the matrix, wherein the first pixel is adjacent to the second pixel. Each of the data lines is arranged to be coupled to the plurality of gate line sets for receiving charges accumulated on the first row of pixels. The X-Ray matrix imager is configured to operate based on multiple-gate-line driving scheme and shared-data-line driving scheme.

    • An X-ray imager includes a photo detector, a pixel array, a scan line and a data line. The photo detector includes a plurality of X-ray sensitive particles that are configured to be electrically isolating and to generate charge carriers upon absorption of X-ray photons. In one example embodiment, the photo detector includes a layer of an electrically isolating material, within which the plurality of X-ray sensitive particles are distributed. The pixel array includes multiple pixels each defined by a space between a first surface and a second surface of the layer. The scan line is configured to activate a corresponding row of the pixels in the pixel array. The data line is configured to read data from a corresponding column of the pixels in the pixel array.

    • The present invention proposes a high speed radiographic system for use with megavolt linear-accelerator pulsed x-ray sources to produce video images of large-area fields. A linear accelerator is positioned above a field of view. X-ray photons are directed through an object of interest traveling and/or colliding within the field of view. A large area scintillator system, either truly continuous or in large continuous adjacent pieces, converts the x-ray photons that pass through the object into visible light, and an arrangement of cameras, focused at that plane, where each camera sees a sub-area of the entire scintillator, and these sub-areas overlap somewhat to cover the entire scintillator. The resulting images generated in each camera are synchronized to produce one contiguous, synchronized stream of images.

    • A method for determining a radiation therapy dose distribution starts with selecting and downloading a treatment type from a database. Then an organ at risk (OAR) distance to target map is determined, wherein the OAR distance to target map comprises distances to a target organ for respective portions of at least one OAR, and wherein the OAR distances are determined from at least one segmented patient organ image. Now a cohort average dose distance to target histogram is selected and downloaded from the database. After which, a dose value to the portions of the at least one OAR are assigned to form a first 3D dose distribution map, wherein the dose values are from the selected cohort average dose distance to target histogram. Now a second 3D dose distribution map is determined based on a field arrangement determined by the treatment type, and the first 3D dose distribution map. Finally, a dose distance to target histogram is calculated for the patient using the second 3D dose distribution map and the distance to target map.
    • 用于确定放射治疗剂量分布的方法从从数据库中选择和下载治疗类型开始。 然后确定距目标图的距离风险(OAR)的距离,其中到目标地图的OAR距离包括至少一个OAR的相应部分到目标器官的距离,并且其中OAR距离由至少一个分段患者 器官形象。 现在,从数据库中选择并下载到目标直方图的队列平均剂量距离。 之后,分配至少一个OAR的部分的剂量值以形成第一3D剂量分布图,其中剂量值来自所选择的队列平均剂量距离与目标直方图。 现在基于由治疗类型确定的场排列和第一3D剂量分布图确定第二3D剂量分布图。 最后,使用第二3D剂量分布图和到目标图的距离为患者计算与目标直方图的剂量距离。
