    摘要: An image processing apparatus (400) comprises a SIMD processor (401) which scans an image frame for regions of interest (step 301), for example corresponding to regions having objects or lines of interest. Each region of interest is rescanned to an orthogonal grid. The orthogonal grids are then floorplanned so that they are rearranged into a smaller subset of image lines. The floorplanning consists of mapping a set of rectangles into a compressed frame portion. Optionally, the rectangles can be rotated in order to allow the rectangles to be packed more densely. The SIMD processor (401) then processes the floorplanned image data (step 307). Once the image data has been processed by the SIMD processor, the DSP (405) re-associates the processed data (step 309), using information stored during floorplanning. The image processing apparatus results in a more efficient use of the SIMD processor (401).

    摘要: A computed tomography scanner (10) includes a plurality of detector elements (100). The signals generated by the detector elements (100) may include an error component which can lead to artifacts in a reconstructed image. An apparatus includes a signal level detector (208) and a signal change detector (210) which evaluate the characteristics of a signal generated by a first detector element during the scan. The apparatus also includes a signal comparator (214) which evaluates a calibrated version of the signal generated by the first detector in relation to a signal generated by a second radiation sensitive detector element. Based on the results of the evaluations, a signal corrector (218) corrects temporal portions of the calibrated first detector signal which are suspected to lead to an artifact.

    摘要: The method (1) according to the invention may be schematically divided into three major phases. Phase (2) comprises step (3) of acquiring a suitable dataset, which is then subjected to a suitable binary segmentation at step (4) results of which are being accessed at step (5). The results comprise temporally sequenced binary coded images, whereby image portions corresponding to blood are labeled as unity, the rest is set to zero. The subsequent phase (12) of the method according to the invention is directed to performing the image processing for segmenting a structure. At step (8) a computation is performed whereby a preceding binary coded image (8a) corresponding to a phase from the temporal sequence is subtracted from a subsequent binary coded image 8b corresponding to a phase yielding a multi-dimensional temporal feature map (8c). At step (9) spatial positions corresponding to a certain voxel value are derived and are used to segment the structure. A pre-defined deformable shape model is accessed at step (11), which is then deformed at step (14) in accordance with spatial coordinates, derived at step (9). Preferably, the segmentation result is stored at step (16). Finally, during a further phase (22) of the method according to the invention, the segmentation results are displayed at step (18) using suitable display means. Preferably, the segmented surface is overlaid on the original data using a two, three or four-dimensional visualization technique. Still preferable, to ease comprehension of the result, the segmented surface is presented as a color-code in a suitable transparency mode. The invention further relates to an apparatus and a computer program for segmenting a structure in a dataset.
