Abstract

We propose a new system for patient’s head positioning for radiology and radiotherapy. The system is constituted of two low-cost digital cameras and a digital projector. As a first step a bright pattern is projected onto the subject’s face and a 3D model of the face is reconstructed in real-time. The pattern guides the selection of feature regions of the face: the eyes, the lips and the nose. Inside these regions features are recognized using image processing techniques; 3D many-fold analysis can improve this stage. From these features the position and orientation over time of the face can be determined.
