Surficial ratio computing method for tomographic image, involves producing contour line in tomographic image, and computing surfaces of regions and surficial ratio based on determined contour lines

摘要

The method involves determining a contour line (22) for a region. A copied contour line is created and represented in a tomographic image (24). Another contour line (23) is produced in the tomographic image by an interactive adjustment of the copied contour line to another region. Surfaces (20, 21) of the regions and surficial ratio (31) are computed based on the determined contour lines. The contour line (22) is determined automatically based on digital image processing methods. The contour line (20) is superimposed in the tomographic image. An independent claim is also included for a tomography equipment provided with control and computer units.
