Microwave-induced thermoacoustic tomography (TAT) is an emerging non-invasive imaging technology. This study opens a new direction for TAT to image the rat tibia fracture. The TAT system we used consists of a pulsed microwave source, a focusing transducer, a step rotation system, a data acquisition device and a data reconstruction system. In this work, we investigate the feasibility of TAT for detecting tibia fracture in a rat model. Both in vitro and in vivo TAT imaging experiments were conducted. The results obtained indicate that the TAT can clearly reveal the structural characteristics of the hind limbs and the differences between normal and post-fracture tibia. This study demonstrates that TAT may have the potential to be a new imaging tool for basic research and clinical diagnosis of bone diseases.
