The internal anatomy of a patient can be difficult for clinicians and other patients to visualize and analyzed in context. The ability to project medical images (CT and MRI scans) directly onto a patient's body helps those viewing these images to recover missing anatomical context for more accurate interpretation. This paper proposes such a system. Various types of images can be displayed using volume rendering techniques for realistic visualization of the internal anatomy and 3D models from segmented images. Calibration is performed on multiple systems to obtain an accurate common coordinate system, as well as correcting visual distortions from the cameras and the projector. This projected AR system provides a common perspective that is not tied to an individual point-of-view which can be used by others such as a surgical team. The system is easily extendable to other display technology and has many potential applications including education, surgical planning, laparoscopic surgery, and entertainment.
