Research Abstract

In order to maximize synergic performance of computer-assisted detection/diagnosis (CAD) system and the radiologists, we clarified reading characteristics of radiologists in a routine reading environment integrated with CAD. We also realized adaptive CAD result presentation for each radiologist based on reading characteristics of the radiologists.
