    摘要: A method and apparatus are provided to improve large field of view CT image acquisition by using at least two scanning procedures: (i) one with the radiation source and detector centered and (ii) one in an offset configuration. The imaging data obtained from both of the scanning procedures is used in the reconstruction of the image. In addition, a method and apparatus are provided for detecting motion in a reconstructed image by generating a motion map that is indicative of the regions of the reconstructed image that are affected by motion artifacts. Optionally, the motion map may be used for motion estimation and/or motion compensation to prevent or diminish motion artifacts in the resulting reconstructed image. An optional method for generating a refined motion map is also provided.

    摘要: A method and apparatus are provided to improve CT image acquisition using a displaced acquisition geometry. A CT apparatus may be used having a source (102) and a detector (104) transversely displaced from a center (114) of a field of view (118) during acquisition of the projection data. The amount of transverse displacement may be determined based on the size of the object (108). The source and the detector may be adjusted to vary the size of the transverse field of view. The first data set acquired by the detector may be reconstructed and used to simulate missing projection data that could not be acquired by the detector at each projection angle. The measured projection data and the simulated projection data may be used to obtain a second data set. The second data set may be compared to the first data set to produce a corrected data set.

    摘要: When performing image-guided biopsy of an anatomical structure in a patient, a target anatomical patient region containing biopsy target is imaged using both SPECT and XCT concurrently. 3D SPECT and XCT image data is fused to generate a fused 3D reference image that is overlaid on 2D patient image(s) generated during the biopsy procedure to generate an overlay image. The overlay image also includes a planned path or trajectory for a biopsy instrument. The 2D patient images are generated using SPECT and/or XCT, and are updated periodically to show biopsy instrument position and progress.

    摘要: The present invention relates to a detection values correction apparatus for correcting detection values of a projection image of a multi-energy imaging system. A scatter contribution providing unit provides scatter contributions for different intensities, different energies and different locations on the detection surface of the detection values. A scatter contributions combining unit combines scatter contributions for correcting a detection value, wherein the combined scatter contributions represent the contribution of the scatter, which is caused by radiation of the other detection values of the projection image, to the detection value to be corrected and wherein the scatter contributions are combined under consideration of the intensity, energy and location on the detection surface of the other detection values. A correction unit scatter corrects the detection value of the projection image by using the combined scatter contributions.
