Micro X-ray CT
Using micro-X-ray CT as a core technology, we are developing methods to visualize and quantify the fine internal morphology of biological tissues with high precision in a non-destructive manner.
- Development of phase-contrast micro-X-ray CT systems
- Investigation of image reconstruction methods using sparse projection data
- Establishment of fundamental technologies for morphological analysis and quantification of three-dimensional images
OCT
We are developing automated analysis frameworks to reliably extract tissue structures and vascular information from three-dimensional images acquired using optical coherence tomography (OCT).
- Segmentation and quantitative analysis of three-dimensional choroidal structures
- Quantitative evaluation of tissue structures in OCT images of diseased eyes
