主　　题：X-ray-induced acoustic computed tomography(XACT) ring artifacts artifacts correction 

摘      要：X-ray-induced acoustic computed tomography(XACT)is a hybrid imaging modality for detecting X-ray absorption distribution via ultrasound *** facilitates imaging from a single projection X-ray illumination,thus reducing the radiation exposure and improving imaging *** detector response caused by the interference between multichannel data acquisition for ring array transducers and amplifier systems yields ring artifacts in the reconstructed XACT images,which compromises the image *** propose model-based algorithms for ring artifacts corrected XACT imaging and demonstrate their effcacy on numerical and experimental *** corrected reconstructions indicate significantly reduced ring artifacts as compared to their conventional counterparts.
