Title:
SYSTEM AND METHOD FOR ESTIMATING BOUNDARY USING CT MEASUREMENT
Document Type and Number:
Japanese Patent JP2006017714
Kind Code:
A
Abstract:
To provide a technique for CT reconstitution used in CT measurement.
A boundary unit CT reconstitution method includes a process 48 for setting initially a boundary of a specimen to acquire an estimated boundary 50, a process for defining a forward model based on the estimated boundary 50, a process for linearizing the forward model to acquire a system matrix 54, and a process for realizing a repeated image reconstituting process, using the system matrix 54, so as to update the estimated boundary 50. The boundary corresponds to one ridge line in one area having substantially uniform attenuation.
