    摘要: A method of and system for the 3-D reconstruction of an image from 2-D cone-beam tomography projections is disclosed in which a circle-plus-arc data acquisition geometry is utilized to provide a complete set of data so that an exact 3-D reconstruction is obtained. A volume CT scanner which uses a cone-beam x-ray source and a 2-D detector is utilized in which one set of cone-beam projections is acquired while rotating the x-ray tube and detector on the CT gantry and then another set of projections is acquired while tilting the gantry by a small angle. The projection data is preweighted and the partial derivatives of the preweighted projection data are calculated. Those calculated partial derivatives are rebinned to the first derivative of the Radon transform, for both the circular orbit data and the arc orbit data. The second partial derivative of the Radon transform is then calculated and then the reconstructed 3-D images are obtained by backprojecting using the inverse Radon transform.

    摘要: A method is disclosed for acquiring a high speed dual-energy image pair using a pixilated digital detector. A single pixilated digital detector acquires and encodes two separate images in effectively one image, eliminating the need to read out a first image prior to acquiring a second image. The encoded information is then utilized to obtain two distinct dual-energy images which may be decomposed to form bone and soft-tissue only images.

    摘要: A display controller including a pixel processor which processes working pixel data for each pixel of a frame, and which includes an overlap detector, a collision detector, and a construction processor. The overlap detector detects an overlap when any new pixel value of a new update region is within a region of a current update of the frame. The collision detector issues a correction request when at least one pixel within the overlap region has a begin pixel value prior to the current update that is different from an end pixel value provided by the current update, and when a new pixel value provided by the new update for the pixel is different from the end pixel value. The construction processor updates the working pixel data before the current update is completed using a new pixel value for each non-overlapping pixel.

    摘要: Outer-loop power control methods and apparatus are disclosed. In an exemplary embodiment, a short-term block error rate is measured for a received signal, and a coarse adjustment to a target signal-to-interference ratio (SIR) is calculated as a function of the short-term block error rate, a target block error rate, and a first loop tuning parameter. In some embodiments, a fine adjustment to the target SIR is also calculated, as a function of a smoothed block error rate, the target block error rate, and a second loop tuning parameter. The coarse adjustment provides quick responsiveness to received block errors, while the fine adjustment moderates the coarse adjustments by accounting for a longer-term view of the received block error rate. The target SIR adjustments disclosed herein may be computed in each of several iterations of an outer-loop power control loop.
