Abstract
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.
