Abstract (en)
[origin: WO2013186090A1] The invention relates to a method for determining functional volumes for searching for kinetics that represent the variation in the concentration of a radioactive tracer in a biological tissue area, wherein the method is applied to spatial components (106) and includes the following steps, which are applied iteratively (111) according to a Markov chain Monte-Carlo method: a step (108) for generating a set (formula A) consisting of a set of candidate kinetics associated with probability values for the occurrence of said kinetics, said values depending on the radioactive tracer concentration lambda; a labeling step (109) during which, for each spatial component of index k (106), the selection probabilities for the kinetics of the set (formula B) are weighted (102) by inserting a function lambda kappa therein that is representative of the radioactive tracer concentration in said component, so as to obtain a set of indicator values (103), an indicator value D k denoting the kinetics with which the spatial component k is associated; and a step (110) for constructing functional volumes, a functional volume VF j consisting of the set of spatial components that share the same indicator value D k .
