Specialties:

Medical Imaging
Research Interests:

Dr. Johnson is the Charles E. Putman University Professor of Radiology, Physics, and Biomedical Engineering and Director of the Duke Center for In Vivo Microscopy (CIVM). The CIVM is an NIH NCRR/NIBIB national Biomedical Technology Resource Center with a mission to develop novel technologies for preclinical imaging (basic sciences) and apply the technologies to critical biomedical questions. Dr. Johnson was one of the first researchers to bring Paul Lauterbur's vision of magnetic resonance (MR) microscopy to practice as described in his paper, "Nuclear magnetic resonance imaging at microscopic resolution" (J Magn Reson 68:129-137, 1986). He is involved in both the engineering physics required to extend the resolution of MR imaging and in a broad range of applications in the basic sciences.

Areas of Interest:

magnetic resonance imaging
magnetic resonance histology
small animal imaging
