Aspect MR is proud to add Prof. Allan G. Johnson, Duke University to its Scientific Advisory team.
Dr. Johnson is Director of the Center for In Vivo Microscopy, an NIH/NCRR National Biomedical Technology Resource Center. He received his PhD in Physics from Duke University in 1974 in electron spin resonance under Professor Walter Gordy. He was responsible for installing the first CT system at Duke in 1974 (the 2nd CT system in the US). From 1981-83 he worked with GE to install the world’s first high field (1.5T) clinical MRI system. He holds appointments in Radiology, Physics, and Biomedical Engineering as the Charles E. Putman University Professor. He is co-author on more than 250 peer-reviewed papers. Dr. Johnson is the principal investigator of the Duke Molecular Imaging Center supported by the National Cancer Institute to develop new imaging strategies for the detection and characterization of cancer and the application of those techniques in preclinical studies. He is also a principal investigator in the Mouse Biomedical Informatics Research Network (MBIRN), a multi-institutional collaboration that integrates studies in the mouse from millimeter to submicron resolution. Dr. Johnson’s personal research is in magnetic resonance histology (MRH), the application of MR microscopy to the study of tissue architecture. The use of MRH for morphologic phenotyping in the mouse was first suggested by Dr. Johnson and his colleagues in 1993. More recently MRH has been extended to 21 microns in the mouse brain for high throughput phenotyping. Dr. Johnson and his team are currently focused on extending the technology to achieve spatial resolution approaching the theoretical limit of ~10 microns.
