Paradoxical labeling of radiosurgically treated quiescent tumors with Ki67, a marker of cellular proliferation.

abstract：:Computerized brain atlas is a new application area in the practical use of stereotactic neurosurgery. Our approach provides a solution for the straightforward definition of a coordinate system (CA-CP), localization of the selected target point, trepanation points and trajectory transformation of the stereotactic elect...
