摘要： The invention relates to a method (100) of processing temporally acquired image data comprising an obtaining step (105) for obtaining the temporally acquired image data, a computing step (110) for computing a time- variability map on the basis of the temporally acquired image data, a classifying step (120) for classifying locations of the temporally acquired image data on the basis of the time-variability map, and a determining step (125) for determining an artifact region and a non-artifact region in the temporally acquired image data on the basis of the classified locations. After determining the artifact region and the non-artifact region, detecting an object in a detecting step (130) is limited to the non-artifact region. This advantageously reduces the risk of falsely identifying the detected object as an object of interest.

摘要： The invention relates to a medical image processing system comprising means for identifying a boundary of the object, and reference points of said object boundary and for decomposing said object boundary into boundary unit elements, centred at the reference points, means for coding each reference point including spatial information and intensity information using dipoles or magnetic moments; computing transform coefficients from said coding data. A finite number of said coefficients is used for representing said object boundary by a polynomial transform function (e.g. Hermite polynomials). This system has means for comparing, matching, correlating, smoothing corresponding boundary portions of the object in different images, only by performing operations on the transform coefficients. These operations yield rotation, translation, scale change transform coefficients.

摘要： The present invention relates to a device for automatically segmenting and preparing an image for further processing. The device automatically maps the organs present on the picture according to preset rules that are representative of conventional physical and anatomical knowledge. The rules include the definition of an initial organ that the device needs to look for first and then, once the device has localized the initial organ, the device follows anatomical rules and localizes further organs. Ultimately, automatic segmentation is done on one or more of the organs that have been localized. The image is then pre-processed for potential further processing.
