| Abstract |
|---|
| A central problem in cranio-maxillofacial (CMF) surgery is to restore the normal anatomy of the skeleton after defects, e.g., malformations, tumours, and trauma to the face. With careful pre-operative planning the precision and predictability can be significantly improved of the craniofacial reconstruction. In addition, morbidity can be reduced thanks to reduced time in the operating room. An important component in surgery planning is to be able to accurately measure the extent of anatomical structures. Of particular interest here are the shape and volume of the orbits (eye sockets). These properties can be measured in 3D CT images of the skull, but requires that the orbits can be extracted from the rest of the image, a process called image segmentation. At the Centre for Image Analysis, Uppsala University, one of our projects involves developing an interactive system for segmenting the orbit. When interacting with the 3D objects, the sense of touch has proven an essential complement to our visual perception. In fact, haptic input devices create new possibilities to design interfaces where the user can simultaneously explore and manipulate 3D data in an intuitive way. In this talk, I will present some of the haptic-enabled tools for image analysis, segmentation, and visualization that we have developed. |
