Abstract

In transthoracic echocardiography training, most medical trainees have difficulties achieving a conceptual understanding of spatial relationships between the echocardiography image and the complicated cardiac anatomical structures. A recent tradition of echocardiography training combines a traditional instructor-led workshop with self-directed online learning. In respect to the advance of educational technologies, the interest in three-dimensional (3D) visualisation has been widespread as it can be a part of the interactive learning systems for improving students’ understanding of the complex phenomena in TTE.
Self-paced learning materials equipped with 3D visualisation components is the focus of this thesis. This study proposed methodological and technical aspects of 3D interactive learning systems development which were delivered through two techniques: a computer-based multimedia and an augmented reality (AR) application. This aim was to assess how medical trainees value these two 3D learning systems and what achievement they gain from their uses in reaching basic TTE comprehension. 46 resident doctors who were novice in TTE at the Faculty of Medicine Siriraj Hospital, Thailand were voluntarily recruited in the study. The result indicated that residents’ knowledge gained from each learning system was similar. Comparably, no significant differences between learning systems were found in the usability questionnaire. Additionally, the responses to open-ended questions on experience highlighted a preference for the 3D graphical presentation of AR over the computer screen-based media. Finally, they anticipated that future versions of the AR application might be a mixed reality application equipped with a mock transducer probe for simulating actual TTE exam on a life-size mannequin.
