title = "Gas bubble motion artifact reduction through simultaneous motion estimation and image reconstruction",
abstract = "Motion of gas bubbles (gastrointestinal gas) in abdominal region can produce significant artifacts during on-board CBCT scanning, which adversely affects the imaging quality and limits the process of CBCT-based adaptive planning and image-guided radiotherapy. In this study, we tested the effectiveness of simultaneous motion estimation and image reconstruction technique (SMRIE) for improving CBCT image quality and HU accuracy of abdominal scan. The improved image quality in the simulation study demonstrated that SMRIE technique is promising for on-board CBCT gas bubble motion artifact reduction.",
