To obtain the basic SDE of dynamical collapse models, a change of the probability space is necessary to obtain the correct equation. The Girsanov transformation is the mathematical tool that allow us to connect the two probability spaces. After a brief review of the standard derivation of the SDE, an attempt to interpret this transformation geometrically, using notions like frames and POVM, is presented.
