Thursday, 8th December 2011 The world’s first 3D surface anatomy guide for medical and physiotherapy students, surgical trainees and artists has been developed in Ireland through a unique collaboration between anatomists, artists and engineers. Launched today in the Royal Hibernian Academy (RHA) in Dublin, the two year project, funded by Science Foundation Ireland and the Royal College of Surgeons Ireland (RCSI), has resulted in an on-line 3D guide which shows the motions of muscles and the sites of structures from the surface inwards. It shows how, by using movement, colour, illustration and 3D technology, anatomists, engineers and artists can collaborate to teach the body from the outside in.The project combined artistic representation, engineering expertise and anatomical accuracy into a four hour teaching programme and will shortly be part of the curriculum/training for medical students in Dublin, Bahrain and Kuala Lumpur. Computer aided learning is an elegant and cost-effective solution for medical students as it gives them access to a 3D representation of the human body and helps mitigate the traditional constraints of medical education such as a lack of willing live models.
Stereo-3D or stereoscopic photography was used to create the footage for the project but the technology has been around for a long time. Stereoscopic pictures of Dublin can be found in the National Library dating from 1865. The technology has been through several reincarnations in the past but it is only in the last five years that the technology has caught up with the idea as everyone knows from the explosion of 3D content on the big screen.
“What is less known is that it is still hard to shoot things in stereo-3D. The crew needs to work with two cameras mechanically and electronically coupled to each other. Quite aside from the physical problems of manipulating the camera rig, it turns out that the camera sensors can never be the same. This is bad for stereo-3D viewing and tends to make people feel ill. The engineering challenges centre on fixing the pictures in post-production using signal processing algorithms designed by the Sigmedia group at Trinity,” said Anil Kokaram, associate professor at the Department of Electronic and Electrical Engineering at Trinity College.
