COMPUTER-ASSISTED 3D RECONSTRUCTION OF THE TERMINAL BRANCHES OF THE CEREBRAL-ARTERIES .3. POSTERIOR CEREBRAL-ARTERY AND CIRCLE OF WILLIS

We present a three-dimensional anatomical computer model of the termin al branches of the posterior cerebral artery and circle of Willis, acq uired from equidistant serial anatomical slices of three brains. The r econstructions provide a clear picture from all angles of the complica ted course of the terminal branches of the cerebral arteries. This can help to identify the arteries in conventional and magnetic resonance angiography. Our rendition of the cerebral arteries can be matched wit h CT, MR und PET images to indicate the areas of extension of the indi vidual branches, allowing neuromorphological and functional correlatio ns.
