摘要： A system and a method for extracting regions of interest from a medical image in order to obtain an image useable by a user. The system includes a user interface comprising virtual buttons that the user can select using an input, the buttons enabling the user to control a selected region extraction method using a region growth method to extract a region The region extraction method depend on which virtual buttons are selected by the user. The user interface also includes a window in which the result of extraction of the region of interest can be displayed, as the region is being grown.

摘要： A method for performing magnetic resonance diffusion imaging, comprising: (a) acquiring a sequence of magnetic resonance images of a target body (BS) using diffusion-encoding gradient pulses applied along a set of non-collinear orientations ( ) sampling a three-dimensional orientation space (AR); (b) estimating, from said sequence of images, a set of space- and orientation-dependent parameters representative of molecular diffusion within said target body; wherein said step of estimating a set of space- and orientation-dependent parameters representative of molecular diffusion within said target body is performed in real time by means of an incremental estimator such as a Kalman filter fed by data provided by said magnetic resonance images; characterized in that said three-dimensional orientation space (AR) selectively excludes a set of orientations (FR) for which magnetic resonance signal intensity is attenuated by diffusion below a threshold level.
