FrameWork for Software Production Line

This project has been to develop by Altran, Vaisseau and IRCAD. The Vaisseau, a science-centre situated in Strasbourg, is aimed at children between 3 and 15 years old (http://www.levaisseau.com/)

This video presents a US simulator (called HORUS), which needs a preoperative CT scan of the patient only and its associated 3D skin model from segmentation This video presents a US simulator (called HORUS), which needs a preoperative CT scan of ... [More] the patient only and its associated 3D skin model from segmentation. The user manipulates a haptic feedback system (bottom left) to move the virtual US probe on the 3D model of the patient (right). (A haptic feedback provides the position of the virtual probe in space, and gives the feeling that the probe is touching the skin). Then, the software automatically computes the CT scan image corresponding to the virtual US probe position on the patient skin. An algorithm transforms in real-time this CT image in a simulated US image based on grey level analysis only. Note that the bones and the gas creates shadows as expected. A novice practitioner can then practice moving a US probe and analyse US image with this kind of simulator before an intervention, since it is based on patient data. He can also practice biopsies or tumour thermal-ablation, using a 2nd haptic system to manipulate the needle insertion. Hostettler A., Forest C., Forgione A., Soler L., Marescaux J.
