Innovations in Biomodelling: Rapid Prototyping for Medical Applications at HKU

Dr. Ian Gibson at the Centre for Advanced Product Development Technologies at HKU presents cutting-edge biomodelling techniques utilizing rapid prototyping (RP). This encompasses the conversion of medical data from scans (CT, MRI) into detailed slices for applications such as segmentation and model visualization. With projects ranging from osteotomy planning for Goldenhar syndrome patients to custom implants and artificial joints, the research emphasizes the practical application of 3D models in surgery, enhancing fields like oral and maxillofacial surgery and tissue engineering.
