Claim 15:
16. The non-transitory computer medium of claim 15, wherein the instructions executed by the electronic processor to perform the matching algorithm include
determining whether there is a match between the native candidate lesions for the first phase CT scans and the corresponding registered candidate lesions from the second phase CT scans, wherein when there is a match, determining a signal to noise ratio (SNR) for the native candidate lesions and a SNR for the registered candidate lesions, and selecting the contours of the valid lesions from the corresponding matched candidate lesions having a greater signal to noise ratio;
determining whether there is an out match of the native candidate lesions for the first phase CT scans; and
when there is no match or out match, determining whether the brightness and the size of the native candidate lesion is greater than a size threshold corresponding to a valid lesion and whether the brightness is greater than a brightness threshold corresponding to a valid lesion.
