Abhinav Kumar Jha, M.S., Ph.D.
Instructor of Radiology and Radiological Science
Dr. Abhinav K. Jha is an Instructor in the Division of Medical Imaging Physics, Department of Radiology and Radiological Sciences, Johns Hopkins University School of Medicine.
Dr. Jha obtained his PhD from the College of Optical Sciences, University of Arizona. He was the valedictorian of his graduating batch. In his PhD, Dr. Jha developed novel tools to retrieve clinically relevant information from scattered photons in diffuse optical imaging and gamma-ray imaging.
Dr. Jha’s research is based on the theme that medical images are acquired for a certain clinical task. Thus, the design, optimization, and evaluation of medical imaging systems and methods should be based on the performance in the clinical task. His research includes devising novel tools for quantitative imaging, objective evaluation of image quality, simulating imaging systems, designing image reconstruction methods and image-analysis tools, and the use of high-performance computing in medical imaging.
A major theme of his current research is in improving the application of quantitative imaging in the clinic. Current projects are in developing methods for improved quantitation of clinically relevant quantitative parameters (both in nuclear medicine and diffusion MRI), designing improved imaging systems and optimized protocols for quantitative imaging, and finally, designing frameworks for evaluating these systems and methods with patient data (no-gold-standard evaluation). While most projects are on applications in oncology, there are also projects on transcranial and myocardial imaging.
Dr. Jha has been given several awards for his research, including those from ECOG-ACRIN, Society of Nuclear Medicine and Molecular Imaging, and SPIE Medical Imaging societies.
