Christopher Mitchell, PhD

Sr. Director, Project Management

Dr. Chris Mitchell has more than 25 years of hands-on and leadership experience in the design, development, and characterization of innovative x ray-based imaging systems for medical and industrial applications. Before joining Triple Ring Technologies, Dr. Mitchell served in a variety of positions at Alara, Inc., including VP of R&D and Chief Scientific Officer. While there, he led the development of a patented, award-winning bone densitometer, and several computed radiography-based imaging systems for medical, industrial, and veterinary applications. Prior to Alara, Dr. Mitchell served as Manager, Imaging Technologies, at ARACOR, where he led the development of a number of innovative imaging systems, including high-performance digital radiography, and cone-beam computed tomography for high resolution bone imaging and reverse engineering applications. Chris received his B.A. in applied mathematics from Weber State University, and MS (bioengineering) and Ph.D. (electrical engineering) from the University of Utah. He holds 3 patents in the fields of bone densitometry and computed radiography and has authored or co-authored numerous presentations and journal articles. He is a member of the American Association of Physicists in Medicine (AAPM).
