Hard X‐ray Microscopic Imaging Of Human Breast Tissues

X‐ray microscopy with synchrotron radiation will be a useful tool for innovation of x‐ray imaging in clinical and laboratory settings. It helps us observe detailed internal structure of material samples non‐invasively in air. And, it also has the potential to solve some tough problems of conventional breast imaging if it could evaluate various conditions of breast tissue effectively. A new hard x‐ray microscope with a spatial resolution better than 100 nm was installed at Pohang Light Source, a third generation synchrotron radiation facility in Pohang, Korea. The x‐ray energy was set at 6.95 keV, and the x‐ray beam was monochromatized by W/B4C monochromator. Condenser and objective zone plates were used as x‐ray lenses. Zernike phase plate next to condenser zone plate was introduced for improved contrast imaging. The image of a sample was magnified 30 times by objective zone plate and 20 times by microscope objective, respectively. After additional 10 times digital magnification, the total magnifying powe...
