Abstract : The field of computer-based simulators has grown exponentially in the last few decades, especially in Medicine. Advantages of medical simulators include: 1 provision of a platform where trainees can practice procedures without risk of harm to patients; 2 anatomical fidelity; 3 the ability to train in an environment wherein physiological behaviour is observed, something that is not permitted where in-vitro phantoms are used; 4 flexibility regarding anatomical and pathological variation of test cases that is valuable in the acquisition of experience; 5 quantification of metrics relating to task performance that can be used to monitor trainee performance throughout the learning curve; and 6 cost effectiveness. In this chapter, we will focus on the current state of the art of medical simulators, the relevant parameters required to design a medical simulator, the basic framework of the simulator, methods to produce a computer-based model of patient respiration and finally a description of a simulator for ultrasound guided for liver biopsy. The model that is discussed presents a framework that accurately simulates respiratory motion, allowing for the fine tuning of relevant parameters in order to produce a patient-specific breathing pattern that can then be incorporated into a simulation with real-rime haptic interaction. Thus work was conducted as part CRaIVE collaboration 1, whose aim is to develop simulators specific to interventional radiology.
