报告简介：

    Advances in minimally invasive medical treatments offer significant benefits for patients from reduced postoperative pain, short hospital stay, and reduced complications as compared with traditional open surgery. treatment paradigms are Interventional Radiology (IR), Microneurosurgery and Brachytherapy cancer treatments. These procedures use X-ray, CT and ultrasound to guide specialised instruments such as soft needles, guide wires, catheters and burrholes to treat a range of conditions. Yet high levels of expertise and skills are required from doctors in order to attain these benefits, presenting challenges to the safety and cost effectiveness of medical training in patients.  While fixed and animal models only fulfil some training objectives, they are not an effective substitute for training in patients.  Tests shown that interactive virtual environments can be used to train skills and experience complications in safety, remote from patients.  To date, however, computer systems have been validated to train only a handful of medical procedures.  Current limitations in simulator fidelity include insufficiently detailed geometric data in anatomical models, limited soft tissue modelling techniques, and haptics that fail to emulate the ‘feel’ of real world instrumentation. Even with today’s modern graphics cards, interactions between virtual instruments and a virtual human with complex geometric and physical behaviours in soft tissue places enormous challenges on computer graphics techniques. This presentation introduces two research projects carried in the Technical Animation Research Group at Teesside University, which are aimed at developing advanced real-time physically-based computer animation techniques to modelling and simulating behavioural characteristics of soft tissues, medical instruments and  interactions.
