Sparsity-Driven Reconstruction for FDOT with Anatomical Priors

J.-C. Baritaux, K. Hassler, M. Bucher, S. Sanyal, M. Unser

IEEE Transactions on Medical Imaging, vol. 30, no. 5, pp. 1143-1153, May 2011.



In this paper we propose a method based on (2, 1)-mixed-norm penalization for incorporating a structural prior in FDOT image reconstruction. The effect of (2, 1)-mixed-norm penalization is twofold: first, a sparsifying effect which isolates few anatomical regions where the fluorescent probe has accumulated, and second, a regularization effect inside the selected anatomical regions. After formulating the reconstruction in a variational framework, we analyze the resulting optimization problem and derive a practical numerical method tailored to (2, 1)-mixed-norm regularization. The proposed method includes as particular cases other sparsity promoting regularization methods such as ℓ1-norm penalization and total variation penalization. Results on synthetic and experimental data are presented.
