What is Session 17. Image guided, robotic and miniaturised systems for intervention and therapy II about?

Volumetric imaging of peripheral vessel structures is a method to locate and characterize vascular diseases. In peripheral arterial disease for example, plaque is narrowing the vessel structure causing blood shortage in the lower limbs. Classification of the diseases progression helps to design a proper therapy. Several diagnostic imaging systems are used to acquire tomographic images of the vessel structures. In computed tomography angiography (CTA) and partly in magnetic resonance angiography (MRA), the vessel volume is enhanced by means of intravenous contrast agent (CA). However, CA can lead to allergic reactions and can also be nephrotoxic. Additionally, the radiation dose in CTA, long examination times in MRA and the procedure costs are main disadvantages. Ultrasound (US) imaging systems equipped with a tracking system enabling the reconstruction of 3D datasets could alternatively be used to overcome these drawbacks. Electromagnetic or optical tracking of the US probe is used to link the acquired 2D US images to a coordinate system. With the spatial information a 3D volume is reconstructed and further vessel structures can be segmented and analyzed. However, the electromagnet
