摘要： The invention relates to an image processing method for estimating a brain shift in a patient, said method involving: the processing (100) of a three-dimensional image of the brain of a patient, acquired before a surgical operation, in order to obtain a reference cerebral arterial tree structure of the patient; the processing (200) of three-dimensional images of the brain of the patient, acquired during the operation, in order to at least partially reconstitute a current cerebral arterial tree structure of the patient; the determination (300), from the combination of the reference and current cerebral arterial tree structures, of a field of shift of the vascular tree representing the shift of the current vascular tree in relation to the reference vascular tree; the application (400) of the determined field of shift of the vascular tree to a biomechanical model of the brain of the patient in order to estimate the brain shift of the patient; and the generation (500), from the estimated brain shift, of at least one image of the brain of the patient, in which the brain shift is compensated.

摘要： The invention relates to a method for resetting a set of source points (S) in a reference image representing an organic tissue and a set of destination points (D) in a current image representing the deformed organic tissue. Said method involves the determination of a resetting function (R) by iterative minimisation of a resetting energy Ereg, the resetting function corresponding to a transformation enabling transfer from the source points of the reference image to the corresponding destination points (D) in the current image. The invention is characterised in that the resetting function (R) is an elastic resetting function satisfying the conditions that ensure that the physical criteria of the organic tissue are met, the conditions being: the Jacobian of the elastic resetting function is higher than 0, the resetting function is continuously differentiable, and the resetting function is bijective.
