    • Classroom to Clinic: Merging Education and Research to Efficiently Prototype Medical Devices 

      Hanumara, Nevan C.; Begg, Nikolai D.; Walsh, Conor; Custer, David; Gupta, Rajiv; Osborn, Lynn R.; Slocum, Alexander H. (IEEE, 2013)
      Innovation in patient care requires both clinical and technical skills, and this paper presents the methods and outcomes of a nine-year, clinical-academic collaboration to develop and evaluate new medical device technologies, ...
    • In Vitro Validation of an Artefact Suppression Algorithm in X-Ray Phase-Contrast Computed Tomography 

      Sunaguchi, Naoki; Yuasa, Tetsuya; Hirano, Shin-ichi; Gupta, Rajiv; Ando, Masami (Public Library of Science, 2015)
      X-ray phase-contrast tomography can significantly increase the contrast-resolution of conventional attenuation-contrast imaging, especially for soft-tissue structures that have very similar attenuation. Just as in ...
    • The Massachusetts General Hospital Acute Stroke Imaging Algorithm: An Experience and Evidence Based Approach 

      Gonzalez, Ramon Gilberto; Copen, William Alan; Schaefer, Pamela Whitney; Lev, Michael Howard; Pomerantz, Stuart R.; Rapalino, Otto; Chen, John Wen-Yueh; Hunter, George; Romero, Javier M.; Buchbinder, Bradley R.; Larvie, Mykol; Hirsch, Joshua A.; Gupta, Rajiv (BMJ Publishing Group, 2013)
      The Massachusetts General Hospital Neuroradiology Division employed an experience and evidence based approach to develop a neuroimaging algorithm to best select patients with severe ischemic strokes caused by anterior ...
    • Multiparametric Evaluation of Head and Neck Squamous Cell Carcinoma Using a Single-Source Dual-Energy CT with Fast kVp Switching: State of the Art 

      Lam, Stephanie; Gupta, Rajiv; Kelly, Hillary; Curtin, Hugh D.; Forghani, Reza (MDPI, 2015)
      There is an increasing body of evidence establishing the advantages of dual-energy CT (DECT) for evaluation of head and neck squamous cell carcinoma (HNSCC). Focusing on a single-source DECT system with fast kVp switching, ...
    • Optimal Brain MRI Protocol for New Neurological Complaint 

      Mehan, William A.; González, R. Gilberto; Buchbinder, Bradley R.; Chen, John W.; Copen, William A.; Gupta, Rajiv; Hirsch, Joshua A.; Hunter, George J.; Hunter, Scott; Johnson, Jason M.; Kelly, Hillary R.; Larvie, Mykol; Lev, Michael H.; Pomerantz, Stuart R.; Rapalino, Otto; Rincon, Sandra; Romero, Javier M.; Schaefer, Pamela W.; Shah, Vinil (Public Library of Science, 2014)
      Background/Purpose Patients with neurologic complaints are imaged with MRI protocols that may include many pulse sequences. It has not been documented which sequences are essential. We assessed the diagnostic accuracy of ...
    • Realistic wave-optics simulation of X-ray phase-contrast imaging at a human scale 

      Sung, Yongjin; Segars, W. Paul; Pan, Adam; Ando, Masami; Sheppard, Colin J. R.; Gupta, Rajiv (Nature Publishing Group, 2015)
      X-ray phase-contrast imaging (XPCI) can dramatically improve soft tissue contrast in X-ray medical imaging. Despite worldwide efforts to develop novel XPCI systems, a numerical framework to rigorously predict the performance ...
