Research
Research themes
Focusing on dual-energy CT, low-dose CT, and image reconstruction, we revisit CT imaging from the perspective of radiation physics and work to improve the accuracy and reproducibility of quantitative image evaluation.
Focus area
Low-dose CT
We investigate the relationships among image noise, reproducibility, and acquisition parameters to preserve diagnostically useful information while reducing radiation exposure.
Focus area
Reconstruction & Physics
We analyze how reconstruction algorithms and scan geometry affect CT images and develop predictable, reproducible methods for image evaluation.
Our approach
From measurement to clinical use. A consistent research design.
Starting with system physics, we ask why CT images look the way they do, measure the underlying effects, test reproducibility, and translate the findings into clinically useful methods.
01
Measure
Describe quantitatively
We describe image quality and errors that are difficult to judge visually in terms of physical and statistical quantities.
02
Validate
Test reproducibility
Through phantom experiments and repeated measurements, we test whether findings remain valid across systems and acquisition conditions.
03
Translate
Connect with clinical practice
We translate insights from imaging science into methods that can improve diagnostic accuracy and reduce patient burden.
Collaboration
Research collaboration & enquiries
We welcome research discussions with medical institutions, universities, and industry, as well as enquiries about graduate research. Please feel free to contact us even if the connection with our current themes is still taking shape.
