MEDICAL IMAGING SYSTEM FOR ACCURATE MEASUREMENT EVALUATION OF CHANGES IN A TARGET LESION

摘要

A body part (204) is scanned (20) to produce a first set of imaging data (214A). A target lesion (5, 202A) in the imaging data is identified (30). The body part (204) is rescanned (40) at a subsequent time so as to produce a second set of imaging data (214B). The target lesion (5A, 202B) is identified in the second set of imaging data and the size of the target lesion (5, 202A) is measured in the first and second sets of imaging data to determine two apparent image volumes corresponding to the first and second sets of to imaging data (60). A change in size is estimated (70) by comparing the first and second apparent lesion sizes (30lA, 301B). A variance on the change in size is estimated (80) so as to determine a bound on the change in size measurement.
