Cold Cathode Coherent-Structure Flat Panel X-Ray Source Using Microarray Metal Target

Traditional X-ray imaging has difficulty in differentiating between soft biological tissues due to low absorption contrast. However, the Talbot-Lau grating interferometer (GI) could be a promising solution to this problem by enabling X-ray phase contrast imaging (XPCI). Unfortunately, the G0 grating has some limitations regarding fabrication and efficiency. To overcome this issue, we have developed a new cold cathode coherent-structure flat panel X-ray source (FPXS) that eliminates the need for G0. This innovation has the potential to significantly improve the capabilities of Talbot-Lau GI for phase contrast imaging in the future.
