Recently we report a high resolution XACT imaging technique on Scientific Reports (from the Nature Publishing Group) by Drs. Liangzhong Xiang and Shanshan Tang.
This new imaging modality, X-ray Induced Acoustic Tomography (XACT), takes advantages of high sensitivity to X-ray absorption and high ultrasonic resolution in a single modality. A single projection X-ray exposure is sufficient to generate acoustic signals in 3D space because the X-ray generated acoustic waves are of a spherical nature and propagate in all directions from their point of generation. We demonstrate the successful reconstruction of gold fiducial markers with a spatial resolution of about 350 μm. XACT reveals a new imaging mechanism and provides uncharted opportunities for structural determination with X-ray.
This is a collaborative effort between TRUE lab at OU and Dr. Lei Xing’s lab at Stanford Medical School.
