Three-dimensional Imaging technologies: a priority for the advancement of tissue engineering and a challenge for the Imaging Community.
Journal of biophotonics, 2016Co-Authors: Laura Teodori, Annunziata Crupi, Alessandra Costa, Alberto Diaspro, Susanne Melzer, Attila TárnokAbstract:Tissue engineering/regenerative medicine (TERM) is an interdisciplinary field that applies the principle of engineering and life sciences to restore/replace damaged tissues/organs with in vitro artificially-created ones. Research on TERM quickly moves forward. Today newest technologies and discoveries, such as 3D-/bio-printing, allow in vitro fabrication of ex-novo made tissues/organs, opening the door to wide and probably never-ending application possibilities, from organ transplant to drug discovery, high content screening and replacement of laboratory animals. Imaging techniques are fundamental tools for the characterization of tissue engineering (TE) products at any stage, from biomaterial/scaffold to construct/organ analysis. Indeed, tissue engineers need versatile Imaging methods capable of monitoring not only morphological but also functional and molecular features, allowing three-dimensional (3D) and time-lapse in vivo analysis, in a non-destructive, quantitative, multidimensional analysis of TE constructs, to analyze their pre-implantation quality assessment and their fate after implantation. This review focuses on the newest developments in Imaging technologies and applications in the context of requirements of the different steps of the TERM field, describing strengths and weaknesses of the current Imaging approaches.

k t focuss a general compressed sensing framework for high resolution dynamic mri
Magnetic Resonance in Medicine, 2009Co-Authors: Hong Jung, Kyunghyun Sung, Krishna S Nayak, Jong Chul YeAbstract:A model-based dynamic MRI called k-t BLAST/SENSE has drawn significant attention from the MR Imaging Community because of its improved spatio-temporal resolution. Recently, we showed that the k-t BLAST/SENSE corresponds to the special case of a new dynamic MRI algorithm called k-t FOCUSS that is optimal from a compressed sensing perspective. The main contribution of this article is an extension of k-t FOCUSS to a more general framework with prediction and residual encoding, where the prediction provides an initial estimate and the residual encoding takes care of the remaining residual signals. Two prediction methods, RIGR and motion estimation/compensation scheme, are proposed, which significantly sparsify the residual signals. Then, using a more sophisticated random sampling pattern and optimized temporal transform, the residual signal can be effectively estimated from a very small number of k-t samples. Experimental results show that excellent reconstruction can be achieved even from severely limited k-t samples without aliasing artifacts. Magn Reson Med 61:103–116, 2009.
