Imaging Informatics is the study and application of processes of information and communications technology for the acquisition, manipulation, analysis, and distribution of medical image data.
In this 2012 video, Katherine Andriole, PhD, FSIIM, answers the question "what is imaging informatics?".
(If above video does not play correctly, you may view the video on YouTube.)
For comparison, Dr. Andriole's definition of imaging informatics in 2006:
"Medical imaging informatics is a multidisciplinary field that intersects with the biological sciences, health services, information sciences, medical physics, and engineering.
Imaging informatics touches every aspect of the imaging chain from image creation and acquisition, to image distribution and management, to image storage and retrieval, to image processing, analysis and understanding, to image visualization and data navigation; to image interpretation, reporting, and communications. The field serves as the integrative catalyst for these processes and forms a bridge with imaging and other medical disciplines.
Imaging informatics professionals and scientists specializing in this evolving field are pioneers involved at the intersection of information science, imaging technology and healthcare and require clinical acumen as well as expert understanding of technology."

Though the field has evolved, the definition of imaging informatics is basically the same today as it was in 2006.
