This thesis project proposes the creation of 3D printed cardiac anatomy replicas derived from medical imaging data. The replicas serve as a supplement to current visualization techniques employed in medicine for the purpose of doctor/patient communication. Contemporary visualization techniques are limited by two dimensional display formats, consequently restricting the efficacy of visualization aids provided to patients during the decision making process. This research leverages modern medical imaging modalities with 3D printing technology to generate physical replicas of individual patients’ cardiac anatomy. An outline of the processing techniques involved is explained, and an overview of relevant 3D printing applications within medicine are included within the published thesis. The research project described was assessed using qualitative analysis by a panel of 7 physicians and clinicians from diverse medical disciplines related to cardiology. Semistructured interviews were conducted with the panel in regard to the efficacy of 3D printed cardiac models as used to facilitate doctor/patient communication.
