Innovative Medical Imaging Technology
Among biomedical imaging technologies, image information processing applicable to computer assisted diagnosis and ultra high resolution MRI are focused in this group. Medical image data obtained from such as CT and MRI becomes larger so as to provide medical staff with higher quality images. One of our objectives is to develop image information processing algorithm and systems to assist doctors in extracting necessary information from the huge data by more precise and more effective way. In order to obtain molecular/cell level information, we are also developing the ultra high resolution MRI equipment.

* Biomedical imaging devices
We have been developing an ultra high resolution Magnetic Resonance Imaging (MRI) as a microscopy, "MRI Microscopy". Among imaging technologies, MRI is in an unique position due to its abilities to localize activating parts in biomedical specimen and to distinguish tissue non-invasively. With the MRI Microscopy, we could understand human brain functional images from the molecular and cell biological point of view. We started to develop a new MRI Microscope for small biological tissue using a 14.1 T horizontal bore magnet and a 600 MHz NMR spectrometer.

* Image processing methods and its medical applications
We develop image processing techniques for quantitative analysis of multi dimensional medical images including multi modality images or sequential images. We also develop medical applications such as image guided radiotherapy, image guided intervention, CAD(computer aided diagnosis) system, and so on. An example of the work is shown in the right column figure (4-dimensional cardiac MR tagged imaging and 5-dimensional image processing methods).
