      Chang, Zheng; Cai, Jing; Adamson, Justus; Yin, Fang-Fang; Ren, Lei; Wang, Zhiheng; Yoo, Sua; ... (8 authors) (Journal of applied clinical medical physics, 2012-07-05)
      American Association of Physicists in Medicine (AAPM) task group (TG) 142 has recently published a report to update recommendations of the AAPM TG 40 report and add new recommendations concerning medical accelerators in ...
    • Impact of collimator leaf width and treatment technique on stereotactic radiosurgery and radiotherapy plans for intra- and extracranial lesions. 

      Kirkpatrick, John; Chang, Zheng; Yin, Fang-Fang; Wang, Zhiheng; Wu, Qingrong; Meyer, Jeffrey J; Lu, Mei; ... (8 authors) (Radiation oncology (London, England), 2009-01-21)
      BACKGROUND: This study evaluated the dosimetric impact of various treatment techniques as well as collimator leaf width (2.5 vs 5 mm) for three groups of tumors -- spine tumors, brain tumors abutting the brainstem, and liver ...
    • Investigation of sliced body volume (SBV) as respiratory surrogate. 

      Cai, Jing; Chang, Zheng; Yoo, Sua; O'Daniel, Jennifer; Yin, Fang-Fang; Kelsey, Christopher; Ge, Hong (Journal of applied clinical medical physics, 2013-01-07)
      The purpose of this study was to evaluate the sliced body volume (SBV) as a respiratory surrogate by comparing with the real-time position management (RPM) in phantom and patient cases. Using the SBV surrogate, breathing ...
