          Appeal No. 1998-0745                                                        
          Application 08/216,842                                                      

          correlation in order to ensure that the corresponding features              
          were being compared in the two images.                                      
          We disagree with the examiner’s analysis.  The correlation                  
          table relied on by the examiner is illustrated in Figure 9 of               
          Verdooner.  This table relates to image comparison after images             
          have been aligned and represents changes in a patient from                  
          previous visits.  Unlike appellant, the correlation table is not            
          used to                                                                     
          align images and there is no showing why it would have been                 

          to modify the reference to utilize a correlation table formed in            
          the manner defined in claim 8 to align images.                              
          The examiner has provided no convincing rationale as to why                 
          it would have been obvious to use a correlation table such that             
          image movement means moves two images so that “image information            
          of said at least one reference point coincides with image                   
          information of a corresponding point represented by a maximum               
          numerical value in the correlation table”.  The fact that it was            
          well known to perform various types of processing on image data             
          (answer at page 7) does not establish that appellant’s invention
