Coupling Brain-Tumor Biophysical Models and Diffeomorphic Image RegistrationMS30

We present the SIBIA framework for joint image registration and biophysical inversion. Given an atlas brain MRI and a cancer patient MRI, we invert for patient-specific tumor growth parameters. We couple diffeomorphic image registration between atlas and patient with a reaction-diffusion tumor model. We derive Picard iterative solver schemes for the PDE-constrained optimization formulation of the coupled problem. Several tests for synthetic and clinical datasets assess the performance and convergence in different usage scenarios.
