The X-ray was discovered in 1895, and the usefulness of X-ray imaging has been recognized among many disciplines ever since. However, because the conventional X-ray imaging methods have relied on the absorption of X-ray, weak absorbing strucures, such as biological soft tissues, cannot be imaged with a sufficient signal-to-noise ratio under the allowable X-ray dosage limit. From around mid-1990s, about a century after the discovery of X-ray, the substituting imaging method, the X-ray phase imaging, has been studied in order to overcome this difficulty, and we have been developing its frontier since then.
In our laboratory, we are trying to develop a new measurement method using synchrotron radiation X-rays, which are known for its useful features; brightness and high directionality. The advantage of the X-ray interferometry or the X-ray phase imaging is that an imaging with an extremely high-sensitivity is achievable.
Currently, we are focused on the subjects listed below, mostly related to the X-ray interferometry imaging. We are also trying to apply our method to various objects, and working for its practical appplications such as biomedical imaging as well.
