The field of diagnostic medical imaging has grown at a phenomenal pace over the past few decades. Significant areas of current research include the push for improved dose efficiency in radiological imaging. The ability to efficiently and reliably assess and optimize the performance of new and developing imaging technology (both hardware and algorithms) can help guide the many research, regulatory, and clinical applications. I will cover the need for such assessments in the context of mainstay imaging modalities (like positron emission tomography (PET) and computed tomography (CT)), and will also discuss objective performance measures for a variety of diagnostic imaging tasks. Trained human observers (i.e., clinicians) play an important but complicated role in medical imaging assessments. New adaptive mathematical models being developed at UH have shown promise as human surrogates.
