    • Digital Spectral Separation Methods And Systems For Bioluminescence Imaging 

      Wang, Ge; Shen, Haiou; Liu, Y.; Cong, A.; Cong, W. X.; Wang, Y.; Dubey, P. (Optical Society of America, 2008-01-01)
      We propose a digital spectral separation (DSS) system and methods to extract spectral information optimally from a weak multispectral signal such as in the bioluminescent imaging (BLI) studies. This system utilizes our ...
    • How to Define the Next Generation Cardiac CT Architecture? - a Contemporary Challenge for Interdisciplinary Collaboration 

      Yu, Hengyong; DeMan, Bruno; Carr, Jeff; Frontera, Mark; Zeng, Kai; Bennett, James; Fitzgerald, Paul; Iatrou, Maria; Shen, Haiou; Santago, Peter; Wang, Ge (2010-05-21)
      Cardiovascular diseases are pervasive with high mortality and morbidity at tremendous social and healthcare costs. There are urgent needs for significantly higher fidelity cardiac CT with substantially lower radiation dose, ...
    • Improving the Accuracy of the Diffusion Model in Highly Absorbing Media 

      Cong, Alexander X.; Shen, Haiou; Cong, Wenxiang; Wang, Ge (Hindawi, 2007-08-29)
      The diffusion approximation of the Boltzmann transport equation is most commonly used for describing the photon propagation in turbid media. It produces satisfactory results in weakly absorbing and highly scattering media, ...
    • In Situ Real-Time Chemiluminescence Imaging of Reactive Oxygen Species Formation from Cardiomyocytes 

      Li, Yunbo; Shen, Haiou; Zhu, Hong; Trush, Michael A.; Jiang, Ming; Wang, Ge (Hindawi, 2009-02-25)
      We have applied the highly sensitive chemiluminescence (CL) imagingtechnique to investigate the in situ ROS formation in cultured monolayers of rat H9c2 cardiomyocytes. Photon emission was detected via an innovative imaging ...
    • TIM-OS: A General Monte Carlo Optical Simulator for Biomedical Optics 

      Shen, Haiou; Wang, Ge (2015-11-15)
      A high-performance public-domain Monte Carlo optical simulator is highly desirable to solve complex heterogeneous optical problems in biomedical engineering. Recently, we developed a Tetrahedron-based Inhomogeneous Monte- ...
    • Towards Omni-Tomography-Grand Fusion of Multiple Modalities for Simultaneous Interior Tomography 

      Wang, Ge; Zhang, Jie; Gao, Hao; Weir, Victor; Yu, Hengyong; Cong, Wenxiang; Xu, Xiaochen; Shen, Haiou; Bennett, James; Furth, Mark; Wang, Yue; Vannier, Michael (PLOS, 2012-06-29)
      We recently elevated interior tomography from its origin in computed tomography (CT) to a general tomographic principle, and proved its validity for other tomographic modalities including SPECT, MRI, and others. Here we ...
    • Varying Collimation for Dark-Field Extraction 

      Wang, Ge; Cong, Wenxiang; Shen, Haiou; Zou, Yu (Hindawi, 2010-02-16)
      Although x-ray imaging is widely used in biomedical applications, biological soft tissues have small density changes, leading to low contrast resolution for attenuation-based x-ray imaging. Over the past years, x-ray ...
