    • Techniques are disclosed for ACK/NAK bit bundling in carrier aggregation scenarios. Such measures exemplarily comprise generating a set of acknowledgement bits confirming receipt of payload data of a radio frame in a carrier aggregation mode aggregating a primary and at least one secondary carrier, said radio frame being divided into a plurality of downlink subframes and uplink subframes, each of said downlink subframes comprising at least one codeword per carrier, each of said acknowledgement bits is allocated to one of said codewords of one of said downlink subframes, and applying spatial domain bundling and/or time domain bundling on said set of acknowledgement bits distinctive for each of said primary and said at least one secondary carrier, wherein said spatial domain bundling is an AND operation of all acknowledgement bits allocated to each codeword of one carrier of said primary and said at least one secondary carrier and one downlink subframe.

    • The present invention discloses a method for performing CT imaging on a region of interest of an object under examination, comprising: acquiring the CT projection data of the region of interest; acquiring the CT projection data of region B; selecting a group of PI line segments covering the region of interest, and calculating the reconstruction image value for each PI line segment in the group; and combining the reconstruction image values in all the PI line segments to obtain the image of the region of interest. The present invention further discloses a CT imaging device using this method and a data processor therein. Since the 2D/3D slice image of the region of interest can be exactly reconstructed and obtained as long as the X-ray beam covers the region of interest and the region B, it is possible to use a small-sized detector to perform CT imaging on the region of interest at any position of a large-sized object, which reduces to a great extent the radiation dose of the X-ray during the CT scanning.
    • 本发明公开了一种对被检查物体的感兴趣区域进行CT成像的方法,包括:获取感兴趣区域的CT投影数据; 获取区域B的CT投影数据; 选择覆盖感兴趣区域的一组PI线段,并计算组中每个PI线段的重建图像值; 并且将所有PI线段中的重建图像值组合以获得感兴趣区域的图像。 本发明还公开了一种使用该方法的CT成像装置及其中的数据处理器。 由于只要X射线束覆盖感兴趣区域和区域B,就可以精确地重构和获得感兴趣区域的2D / 3D切片图像,因此可以使用小尺寸检测器来执行CT成像 在大尺寸物体的任何位置处的感兴趣区域,其在CT扫描期间在很大程度上降低X射线的辐射剂量。

    • In some embodiments, systems for capturing scene images and depth geometry are provided, comprising a projector, an optical sensor, and a digital processing device. The projector is capable of being defocused with respect to a scene and projects light having a shifting periodic illumination pattern on the scene. The optical sensor has a plurality of pixels and detects a portion of the radiance of at least one image of the scene at each of the pixels. The digital processing device is capable of being coupled to the optical sensor and obtains a temporal radiance profile from the radiance over a time period for each of the pixels, determines an amount of projection defocus at each of the of pixels using the temporal radiance profile, and, at each of the pixels, computes a depth to the scene at the pixel using the amount of projection defocus at the pixel.
