    • A translatable predictor of human radiation exposure. 

      Abedi, M; Chao, Nelson J; Chute, JP; Dressman, HK; Himburg, Heather; Lucas, J; Minor, K; ... (12 authors) (PLoS One, 2014)
      Terrorism using radiological dirty bombs or improvised nuclear devices is recognized as a major threat to both public health and national security. In the event of a radiological or nuclear disaster, rapid and accurate ...
    • Computed tomography dose index and dose length product for cone-beam CT: Monte Carlo simulations. 

      Samei, Ehsan; Yoshizumi, Terry; Yin, Fang-Fang; Song, Haijun; Kim, Sangroh (Journal of applied clinical medical physics, 2011-01-19)
      Dosimetry in kilovoltage cone beam computed tomography (CBCT) is a challenge due to the limitation of physical measurements. To address this, we used a Monte Carlo (MC) method to estimate the CT dose index (CTDI) and the ...
    • Early hematopoiesis inhibition under chronic radiation exposure in humans. 

      Akleyev, AV; Akushevich, Igor; Dimov, GP; Ukraintseva, Svetlana; Varfolomeyeva, TA; Veremeyeva, Galina A; Yashin, Anatoli I (Radiat Environ Biophys, 2010-05)
      The major goal of this study was to identify and quantitatively describe the association between the characteristics of chronic (low-dose rate) exposure to (low LET) ionizing radiation and cellularity of peripheral blood ...
    • Early hematopoietic effects of chronic radiation exposure in humans. 

      Akleyev, AV; Akushevich, Igor; Dimov, GP; Ukraintseva, Svetlana; Varfolomeyeva, TA; Veremeyeva, Galina A; Yashin, Anatoli I (Health Phys, 2010-09)
      The major goal of this study is to investigate and quantitatively describe the nature of the relationship between the characteristics of chronic exposure to ionizing radiation and specific patterns of hematopoiesis reduction. ...
    • Gene expression signatures that predict radiation exposure in mice and humans. 

      Chao, Nelson J; Chute, JP; Dressman, HK; Ginsburg, Geoffrey Steven; Marshall, D; Meadows, Sarah K; Muramoto, Garrett G; ... (8 authors) (PLoS Med, 2007-04)
      BACKGROUND: The capacity to assess environmental inputs to biological phenotypes is limited by methods that can accurately and quantitatively measure these contributions. One such example can be seen in the context of exposure ...
    • 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 ...
    • Micro-CT of rodents: state-of-the-art and future perspectives. 

      Badea, CT; Clark, Darin P (Phys Med, 2014-09)
      Micron-scale computed tomography (micro-CT) is an essential tool for phenotyping and for elucidating diseases and their therapies. This work is focused on preclinical micro-CT imaging, reviewing relevant principles, technologies, ...
    • Optimization of reduced-dose MDCT of thoracic aorta using iterative reconstruction. 

      Chalian, Hamid; Töre, Hüseyin Gürkan; Entezari, Pegah; Gonzalez-Guindalini, Fernanda Dias; Botelho, Marcos Paulo Ferreira; Yaghmai, Vahid (Journal of computer assisted tomography, 2014-01)
      OBJECTIVE: To evaluate the contribution of iterative reconstruction on image quality of reduced-dose multidetector computed tomography of the thoracic aorta. METHODS: A torso phantom was scanned using two tube potentials ...
    • Response. 

      Harvey, HB; Brink, JA; Frush, DP (Radiology, 2016-02)
    • Spectrotemporal CT data acquisition and reconstruction at low dose. 

      Badea, CT; Clark, Darin P; Kirsch, David Guy; Lee, CL (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. ...
