Abstract:
A method is described for the superimposition of an averaged telencephalic anatomical model and individual CT scans. The model is digitally available and derived from 3-D measurements of 30 post-mortem brains. It is averaged in size in relation to the midintercommissural point. The midintercommissural point in the individual brain is gained from reformed parasagittal projection images. The model is adjusted to the individual CT scan series by scaling and rotating according to the best fit and correspondence of the position of the central sulcus. The method needs no invasive neuroradiological techniques but is based on current computer algorithms.
