摘要： In overlapping reconstruction for multi-slide spiral CT, adjacent slices of an object typically only have small differences. Based on this property, a progressive updating approach for volumetric ct image reconstruction includes a method and apparatus to use the well-known ordered subset expectation maximization (OSEM) formula or other iterative algorithms for spiral CT overlapping reconstruction. The imaging geometry is assumed to be single-slice helical/spiral scanning. To start with, a complete set of projections is synthesized via linear interpolation of data associated with opposite rays for reconstruction of the first slice. Then, new data are incrementally utilized for reconstruction of subsequent slices by updating the previous slice using the OSEM approach. To overcome accumulative errors, traditional reconstruction from a complete set of projections is performed when it is necessary as is determined by dynamically monitoring the relevant errors.

摘要： For the purpose of simplifying software management, an operation console reads projection data at Step S401, generates transmitted data at Step S402, and transmits the data to a server at Step S403. The server receives the transmitted data at Step S451, and executes error correction processing on raw data at step S452. Next, at Step S453, image reconstruction processing is executed based on the raw data corrected at Step S452 to produce an X-ray tomographic image. At Step S454, the data of the X-ray tomographic data is transmitted to the operation console. The operation console then receives the data of the X-ray tomographic image at Step S404, and saves the received data of the X-ray tomographic image or displays it as an image at Step S405.

摘要： In a computed tomography method and apparatus, having a subject with a conical ray beam emanating from a focus and with a matrix-like detector array for detecting the ray beam, while the focus is moved on a spiral path around a system axis relative to the subject, and the detector array supplies output data corresponding to the received radiation. The output data respectively supplied during the motion of the focus on a spiral segment and having a length adequate for the reconstruction of a CT image are divided into output data with respect to sub-segments, with the length of each sub-segments being shorter than the length required for the reconstruction of a CT image. Segment images having an inclined image plane relative to the system axis are reconstructed for the sub-segments. A signal reproducing the time curve of the periodic motion is acquired during the scanning. A z-position on the system axis and a time position with respect to the periodic motion are allocated to the segment images. Segment images belonging to a desired range of z-positions and a desired range of time positions are selected such that the corresponding sub-segments have an overall length adequate for the reconstruction of a CT image. The selected segment images are at least indirectly combined into a resulting CT image with respect to a target image plane.

摘要： In order to obtain an image with artifacts suppressed when a helical scan is conducted employing a multi-row detector with a scan plane tilted, preprocessing such as sensitivity correction is applied to data collected by a helical scan employing a multi-row detector with a scan plane tilted (S1), tilt correcting processing is applied for correcting view-to-view variation of the positions of channels in the detector rows relative to an axis of translation due to the tilt of the scan plane (S2), multi-slice/helical interpolation processing is applied for calculating interpolated data from proximate data in an image reconstruction plane (S3), and backprojection processing is applied to the interpolated data to produce an image (S4).

摘要： A correction method is used for reducing artifacts caused by structures of high x-ray absorption in computer tomography images. By such a method, it is possible for interfering objects to be found both automatically and interactively in a computer tomography image. Relatively large interfering objects are preferably split up into a plurality of smaller interfering objects. The computer tomography image for each pixel of a selected image region is filtered as a function of its position relative to the interfering object.

摘要： A three-dimensional image processing system enables multiple users at distant locations employing ordinary personal computers to construct and observe three-dimensional images simultaneously. In a network environment, a three-dimensional image processing device acquires image data and incorporates it into three-dimensional voxels based on instructions from the computers. The device operates on the three-dimensional voxels using object space domain, opacity and color parameters to construct three-dimensional data and operates on the three-dimensional data using projection processing parameters to construct three-dimensional images. The system sets projection processing parameters for constructing three-dimensional images from three-dimensional data and displays three-dimensional images which may be routed to the various computers via the network.
