Title: Deformation gradient-based zero-pressure configuration recovery for vessels
Inventor: Zhongzhao Teng
IPC: G06T19/00
Filed: 2019-01-28
Abstract: Determining an unpressurised blood vessel configuration (e.g. coronal or carotid artery, vein), comprises providing (S104) an initial (i.e. a ‘normal’ start state) configuration model S(k=1) of the vessel comprising a mesh of N nodes (e.g. originally derived from segmented imaging of the vessel (S101), using MRI, CT, ultrasound), and applying (S105) a pressure (e.g. systolic or diastolic average) to the model S(k) to obtain a pressurised configuration model D(k). A deformation gradient F(k), wherein D(k) = F(S(k)), is determined (S106), and for each node, a displacement E(k) is calculated (S107) representing the difference between the pressurised configuration model and the configuration model at each node. An updated configuration model S(k+1) = D(k) - F-1(k)⊙E(k) is calculated (S108), wherein F-1(k) is the inverse of the deformation gradient and ⊙ is an elementwise product. If a difference between the maximum value of E(k) and E(k-1) is more than an error threshold (Y), the pressurising, deformation gradient determination, displacement calculation and updated model calculation steps are repeated, otherwise (N) S(k) (as iterated) is output as the unpressurised blood vessel configuration (S109). Use of the deformation gradient accelerates convergence. Zero pressure geometry required by Finite Element Analysis (FEA) of vessels is improved.
