[X-ray Phase Contrast Imaging]
X-RAY PHASE-CONTRAST (PC) IMAGING AND TOMOGRAPHY
The field of X-ray imaging is currently undergoing a revolution due to the development of X-ray phase-contrast (PC) imaging methods that have dramatic advantages over conventional radiographic X-ray imaging systems. Conventional X-ray imaging methods are based on absorption effects and therefore image contrast is due to differences only in the X-ray absorption properties of the tissues. This can be problematic when imaging soft tissues that do not possess large variations in X-ray absorption properties. There remains an important need for optimization, improvement, characterization, and validation of PC imaging methods, to make them suitable for routine and widespread use. Our research group is actively developing image formation methods for X-ray PC imaging and is collaborating with several groups (including Electronics and Telecommunications Research Institute (ETRI), Yonsei university, and Stanford University) and other institutions to translate the technology to address important needs in clinical and preclinical medicine.
