In this paper we present modeling, analysis and synthesis of visual behaviors of agents engaged in navi-gational tasks. We consider situations in which two agents can navigate independently or in cooperation. For the purpose of modeling the behaviors we have adopted a formalism from the Discrete Events Systems (DES) theory, suitable for investigating control-theoretic issues of a system. The fo...

With advances in devices and techniques, the success rates of percutaneous coronary intervention(PCI)and endovascular treatment (EVT)remarkablly increased. This increased success has facilitated the pursuit of less invasive procedures, such lower dose of contrast agent, lower exposure, and shorter procedure time. Taking advantage of intravascular imaging techniques such as intravascular ultraso...
