Abstract :
With the knowledge of cell interaction between tumor and therapeutic cells, it can help to develop cell-based therapeutic strategies such as immunotherapy. The ability to track cells in vivo or in vitro requires development of molecular probes and 3D molecular imaging systems. Specifically, 3D in vitro models allow the use of various imaging tools in cell tracking. To this end, optical resolution photoacoustic microscopy (OR-PAM) has the potential as a molecular imaging tool for cell migration analysis in 3D cultures. OR-PAM provides superior spatial resolution of micrometer level at 1-mm depth. With the aid of exogenous molecular contrast agents, OR-PAM systems can further provide cellular information. In this study, we verified the feasibility of gold nanorods (AuNRs) contrast-enhanced OR-PAM technique for depicting an in vitro 3D tumor microenvironment. The technique can provide better morphology in 3D microenvironment and is highly potential for preclinical development. The AuNRs contrast-enhanced OR-PAM is highly potential for preclinical screening requiring cell tracking. We will present our system setup, as well as experimental results on the relations between matrix stiffness and cancer cell behaviors. The implication in cancer mechanobiology will also be discussed.

Abstract :
The project, “Multidisciplinary Computational Anatomy and its Application to Highly Intelligent Diagnosis and Therapy (multidisciplinary computational anatomy in short)” was funded by MEXT Grant-in-Aid for Scientific Research on Innovative Areas in 2014. Multidisciplinary computational anatomy comprises scientific research on innovative areas based on medical images integrated with those factors of information such as (1) the spatial axis, from a cell size to an organ size level, (2) the time series axis, from an embryo to post mortem body, (3) the functional axis, such as medical image modality, physiology or metabolism, and (4) the pathological axis, from a healthy physical condition to a diseased condition. It is a new scientific area that establishes a mathematical analysis base for a comprehensive and useful understanding of the human body, and defines a new mathematical method for early detection and a highly intelligent diagnosis and treatment for the diseases with a difficulty in them. A new grant for the international activity has been accepted by MEXT last year and it has started to accelerate the global initiatives in collaboration with foreign leading centers in the new frontier over the world.

Abstract :
Compressed sensing (CS) has become one of the most important topics in modern medical imaging. CS overcomes classical spatio- and/or temporal- resolution limits in many medical imaging systems, as well as gives an opportunity to design new types of systems. Moreover, the sparse recovery principle in CS is closely related to the sparse coding principle in recent deep learning. In this talk, I will review our 10 year research activities on compressed sensing and deep learning approaches for medical imaging such as MR, CT, etc. Specifically, I will focus on our pioneering works in this field - k-t FOCUSS, ALOHA, WaveNet and its variations that can overcome the many of the limitation of the existing methods.
