摘要： A method of aligning a pair of images with (101) a first image and a second image, wherein said images comprise a plurality of intensities corresponding to a domain of points in a D-dimensional space includes identifying (102) feature points on both images using the same criteria, computing (103) a feature vector for each feature point, measuring a feature dissimilarity (104) for each pair of feature vectors, wherein a first feature vector of each pair is associated with a first feature point on the first image, and a second feature vector of each pair is associated with a second feature point on the second image. A correspondence mapping (105) for each pair of feature points is determined using the feature dissimilarity associated with each feature point pair, and an image transformation (106) is defined to align (108) the second image with the first image using one or more pairs of feature points that are least dissimilar.

摘要： In a method and apparatus for determination of coefficients of a diffusion tensor to describe a diffusion process within a subject, spatially-resolved, variously diffusion-coded diffusion data are generated from volume elements of the subject under consideration of control data for various diffusion codings. Intermediate diffusion data are generated for each volume element from diffusion data measured with a first diffusion coding. Updated intermediate diffusion data are then determined for each volume element from diffusion data generated preceding the intermediate diffusion data and current diffusion data measured with a different diffusion coding. Components of a diffusion tensor are determined from the last determined, updated intermediate diffusion data after multiple updates with various diffusion codings.

摘要： In a method and apparatus for incremental calculation of a general linear model given intermittent correlation of the model functions, data composed of a number of data sets with a number of different random samples are processed. For each independent random sample contained in the data set, a dependency on an order quantity is compared with the dependency on the order quantity in model functions contained in a model matrix G using the general linear model in order to check the occurrence of specific characteristics in the dependency of the random sample on the order quantity. The calculation of the general linear model ensues incrementally from data set to data set. Before the calculations for the data of a data set, a check is made as to whether the model functions contained in the model matrix G exhibit orthogonal portions to a sufficient degree in a segment (represented by the data set) of the dependency on the order quantity for the calculations. Given a degree of parallelism that is too high, one or more model functions of the model matrix G that interfere with the orthogonality are masked out to a predeterminable degree in the calculations for this data set, in order to achieve the sufficient degree of orthogonal portions. An incremental calculation of the general linear model with corresponding output of intermediate results is thereby enabled, even given the presence of intermittent correlating model functions in the model matrix.
