    • Investigation of sliced body volume (SBV) as respiratory surrogate. 

      Cai, Jing; Chang, Zheng; O'Daniel, Jennifer; Yoo, Sua; Ge, Hong; Kelsey, Christopher; Yin, Fang-Fang (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 ...

    • Micro-CT imaging of breast tumors in rodents using a liposomal, nanoparticle contrast agent. 

      Samei, Ehsan; Saunders, Robert S; Badea, Cristian T; Ghaghada, Ketan B; Hedlund, Laurence W; Qi, Yi; Yuan, Hong; ... (9 authors) (Int J Nanomedicine, 2009)
      A long circulating liposomal, nanoscale blood pool agent encapsulating traditional iodinated contrast agent (65 mg I/mL) was used for micro-computed tomography (CT) imaging of rats implanted with R3230AC mammary carcinoma. ...

    • Plate-specific gain map correction for the improvement of detective quantum efficiency in computed radiography. 

      Schnell, Erich A. (2010)
      The purpose of this work is to improve the NPS, and thus DQE, of CR images by correcting for pixel-to-pixel gain variations specific to each plate. Ten high-exposure open field images were taken with an RQA5 spectrum, with ...

    • Spectrotemporal CT data acquisition and reconstruction at low dose. 

      Clark, Darin P; Lee, Chang-Lung; Kirsch, David G; Badea, Cristian T (Med Phys, 2015-11)
      PURPOSE: X-ray computed tomography (CT) is widely used, both clinically and preclinically, for fast, high-resolution anatomic imaging; however, compelling opportunities exist to expand its use in functional imaging applications. ...
