Research Area

We integrate biomedical imaging with information science approaches such as statistical learning, computational simulation, and augmented reality to create knowledge and foster innovation in the field of computational biomedicine. We currently have four main research areas (Fig. 1):

Virtualized human anatomy (Fig. 2)

We create models of human anatomy for each subject from 3D biomedical images. By integrating 3D image analysis and statistical learning, we also create models of variability in anatomical shape and image appearance throughout a population. We call these computational anatomy models. We also construct computational models of, for example, physical or physiological functions to seek comprehensive understanding of a subject’s body.

Diagnosis and treatment planning (Fig. 3)

We develop systems to support critical decision-making in diagnosis and therapeutic planning. These systems integrate patient-specific biomedical simulations with virtualized human anatomy and statistical predictions from clinical databases (known as “medical big data”).

Image-guided therapy (Fig. 4)

We are developing a surgical navigation system to provide surgeons with intraoperative guidance throughby real-time fusion of the surgical field and the virtualized human anatomy. Our goal is to develop "intelligence" in surgery based on statistical learning and computational simulations. This will enable the predictionng ofthe changing conditions of a patients during an operations in order to perform optimal surgical procedures.

Postoperative assessment (Fig. 5)

Medical treatment quality assurance requires proper assessment of the surgical outcomes. We develop ways to quantitatively evaluate the motion of patients who have had surgery on their skeletal structure, such as in orthopedic and craniofacial operations, where detecting subtle changes in locomotion is crucial in predicting long-term outcome.

Key Features

Our laboratory features a highly integrated research environment for information science, biomedical imaging, clinical medicine, and other related technologies. We have a number of medical and technical collaborators, including companies, working together within Japan and throughout the world. We fully utilize our unique environment and our network of researchers to pursue our work in imaging-based computational biomedicine.
