At Nanyang Technological University’s Lee Kong Chian School of Medicine, students can now study the human anatomy using 3D-printed replicas of human organs.
Assistant Professor Reddy Mogali, head of anatomy, says that having this learning tool, besides cadavers, would help students appreciate structural variations in the same organ from different individuals.
Traditionally, medical students work with cadavers, both wet and plastinated. Plastinated cadavers are dehydrated specimens that have been injected with silicone. Donated cadavers are generally in short supply.
To print the three-dimensional replicas, a CT scan of the organ is first conducted. Segmentation to identify the various structures of the organ is then done on a computer, to recreate a three-dimensional image to be printed.
