Abstract:
1. A method of compensation for intra-operative brain shift of a living subject, comprising the steps of: a. pro-operatively acquiring brain images of the living subject; b. constructing a statistical atlas, [E], of brain displacements of the living subject from the pro-operatively acquired brain images, wherein [E] comprises a distribution of brain shift solutions corresponding to a pre-operative surgical plan and is in the form of an n×m matrix with n, m being integers; c. intra-operatively measuring brain displacements, {f}, of the living subject, wherein {f} is in the form of a n×1 matrix; d. deriving an intra-operative displacement atlas, [X e. obtaining intra-operative brain shift at least from the intra-operative displacement atlas [X f. compensating for the intra-operative brain shift.
