Tracking of the deformation of a linear structure defined on an image in an image sequence of a deformable organ over time

摘要

The deformation of a linear structure (LS(t1)) on an image (IM (t1)) is followed by defining (DEF) the structure and calculating (CALC) marker point positions (MP(t1)), and (MP(t2)). The parameters of a mathematical expression f(t1/t2) describing the deformation of the organ are determined (DET) from marker points (MP'(t1)), (MP'(t2)) on two images and the expression is used (AP) to define the linear structure after deformation (LS(t2)) Independent claims are made for image capturing and processing equipment and also for a computer program used by the method
