Momose Lab
Machine-translated · View original
A lab that uses the phase of X-rays to reveal what was previously invisible.
AboutAbout the lab
Seeing soft matter through X-ray phase
The Momose Lab aims to develop new measurement methods, with the measurement of X-ray phase as its keyword.
Conventional X-ray transmission imaging creates contrast from differences in absorption between materials, so it has lacked sensitivity for objects made of light elements, such as soft tissue in living bodies and soft matter.
X-ray phase-contrast imaging, which has attracted attention since the mid-1990s, is a technique that can overcome this weakness, and the lab has been at the forefront of its development.
Today, the lab is expanding its applications to the observation of a wide range of materials while also working toward practical uses such as medical diagnostic imaging.
Key terms
- Phase
- A quantity that describes where the peaks and troughs of a wave are located. When a wave passes through matter, its phase shifts.
- Interferometer
- A device that splits a wave in two, then recombines the two parts and measures the phase shift as a fringe pattern.
- Tomography
- A method that computes the internal cross-sections or three-dimensional structure of an object from images taken from many different directions.

ResearchResearch themes
Forming images using X-ray phase gives far higher sensitivity than methods based on absorption. Centered on the Talbot interferometer, which uses transmission gratings, and similar interferometers, the lab conducts research on a variety of X-ray phase imaging techniques.
*Illustrative imageResearch on X-ray interferometric optics
The lab studies optical systems that build interferometers for X-rays, such as the Bonse-Hart interferometer, which is machined from a single crystal of silicon, and the grating-based Talbot interferometer.
*Illustrative imageDevelopment and applications of X-ray phase microscopy
Grating-based methods cannot resolve features smaller than the grating period. The lab is trying to overcome this limit by combining them with X-ray microscopes that magnify the image of the sample.
*Illustrative image4D X-ray phase tomography
This technique adds a time axis to three-dimensional images in order to follow how structures move. The lab uses white synchrotron radiation to speed up phase CT measurements.
*Illustrative imageNeutron phase imaging
Neutrons pass through matter more easily than X-rays and also behave as waves. To extend the concept of phase imaging to neutrons, the lab first developed a transmission grating that uses gadolinium.
