Human observers engage in 2 interrelated processes when interpreting medical images:
perception and analysis. Perception is the unified awareness of the content of a displayed …

The goals of perception research have been outlined at a number of conferences and
workshops(1). Broadly, they include (a) mathematical modeling of the detec-tion of discrete …

The goal of this paper is to provide the reader with an introduction to the importance of
perception research in medical imaging. It is well known that radiologists' performance is not …

The accurate and efficient interpretation of medical images relies on a host of factors. Clearly
the technologies and methods used to acquire, process, transmit, store, and display the …

Technical and diagnostic image quality are distinguished and the limitations of three
methods currently used for assessing diagnostic image quality are discussed. They are …

Medical images constitute a core portion of the information a physician utilizes to render
diagnostic and treatment decisions. At a fundamental level, this diagnostic process involves …

Most academic radiologists will be familiar with receiver operating characteristic (ROC)
studies. Fundamental studies of human observer performance are now usually performed by …

PURPOSE: To present an overview and literature survey of the development and role of the
evaluation of diagnostic performance in radiography. METHODS: The case is made for the …

The quality of medical images must be quantified with reference to specific diagnostic tasks.
Image quality is limited by fundamental physics, engineering limitations, radiation safety …

Interpretation of increasingly complex imaging studies involves multiple intricate tasks
requiring visual evaluation, cognitive processing, and decision-making. At each stage of this …
