Is it possible to implement an intelligent tutoring system that can teach trainee radiologists write complete and correct freeform reports using natural language? That is the question that Dr. Luke Oakden-Rayner (Department of Radiology, Royal Adelaide Hospital) presented to Dr. Amali Weerasinghe and Associate Professor Gustavo Carneiro from the School of Computer Science of the University of Adelaide. This question motivated the implementation of the tutoring system “CRISTAL” during the summer of 2016 by Computer Science undergraduate students Hope Lee, Jayden Barnes and William Gale. The development of CRISTAL is based on the use of state-of-the-art natural language processing and intelligent tutoring methods, and a description of this system is presented in a paper accepted for publication by the International Conference on Intelligent Tutoring System (ITS) 2016, a conference ranked A by the Computing Research and Education (CORE) Association of Australasia. This research group is currently working on extending CRISTAL to a version that will be clinically evaluated at the Royal Adelaide Hospital.
