Dr. Charles Francis, URMC faculty and Dr. Gary Lyman, Duke University, are Principal Investigators on the study. Dr. Mark Frampton, from Pulmonary Medicine, is conducting a clinical trial using ultrasound of the brachial artery to assess pulmonary response to environmental toxins. Clinical parameters for this trial will be assessed by the URMC ultrasound division. 4 The Rochester Center for Biomedical Ultrasound (RCBU) was created at the University of Rochester to unite professionals in engineering, medical, and applied science communities at the University of Rochester, Rochester General Hospital, and the Rochester Institute of Technology. Since its founding in 1986, the RCBU has grown over the years to nearly 100 members, with several visiting scientists from locations around the country. The Center provides a unique collaborative environment where researchers can join together to investigate the use of very high frequency sound waves in medical diagnoses and therapy. The Center’s mission encompasses research, education, and innovation.
