Patent ID: 7813536

Claim:
An abdominal CT image measuring apparatus, comprising: an interface unit, for obtaining two-phase or multi-phase scan images of a part under test, wherein said scan images comprise plain scan images series and enhanced scan image series; a part recognizing unit, for outputting a correspondence between the scan images in two different phases obtained by the interface unit by a registration algorithm, for comparing CT values of corresponding points on the scan images in two different phases, and for determining the corresponding points on the scan images in two different phases belong to the part under test when a difference between the CT values of said corresponding points is greater than or equal to a predetermined threshold; and a characteristic data computing unit, for extracting the CT values of said points representing the part under test, and computing required characteristic data of the part under test based on the difference between the CT values of the points representing a same position of the part under test on the images in different phases.
