.... identifiable structures placed in known positions, such as plastic N shaped tubing filled with CuSO 4 placed strategically for magnetic resonance imaging (MRI) systems [Evans 88] or stereotactic coordinate frames that identify three dimensional coordinates for positron emission tomography (PET) Bergstrom 81, Bohm 83, Bohm 88, Fox 85] Although 25 intrinsic control points are preferable for obvious reasons, there are not always intrinsic points that can be used. For example, precisely placing markers internally is not always possible in diagnostic images[Singh 79] Control points that are ....

....to utilize both sources of information it is necessary to correlate independently acquired MR and PET brain images. Several approaches for registration of MR and PET have been investigated and presented in literature such as techniques based on the use of stereotactic frames or external markers [1], anatomic landmarks [2] and surface or volume matching [3] An accurate and practical volume based registration method has been developed by Arata et al. 4] It is called Iterative Principal Axis Registration (IPAR) In this method a principal axis transform of MR and PET binary volumes is used ....
