The Visible Human digital datasets make it possible to develop computer-based anatomical training systems that use virtual anatomical models (virtual body structures-VBS). Medical schools are combining these virtual training systems and classical anatomy teaching methods that use labeled images and cadaver dissection. In this paper we present a customizable(More)
Major efforts are being made to improve the teaching of human anatomy to foster cognition of visuospatial relationships. The Visible Human Project of the National Library of Medicine makes it possible to create virtual reality-based applications for teaching anatomy. Integration of traditional cadaver and illustration-based methods with Internet-based(More)
Limited sense of touch and vision are some of the difficulties encountered in performing laparoscopic procedures. Haptic simulators can help minimize these difficulties; however, the simulators must be validated prior to actual use. Their effectiveness as a training tool needs to be measured in terms of improvement in surgical skills. LapSkills, a haptic(More)
Most of the current surgical simulators rely on preset anatomical virtual environments (VE). The functionality of a simulator is typically fixed to anatomy-based specific tasks. This rigid design principle makes it difficult to reuse an existing simulator for different surgeries. It also makes it difficult to simulate procedures for specific patients, since(More)
Touch is very important to human, as demonstrated by any child who, when asking to ‘see’ an item, will reach out its hand to palpate and get the ‘feel’ of the object of interest. The ability to simulate sense of touch, using computers, has finally arrived. Human haptics is the sense of touch. Computer haptics is simulating human haptics via a device. This(More)
Generation of credible force feedback renderings adds the sense of touch crucial for the development of a realistic virtual surgical environment. However, a number of difficulties must be overcome before this can be achieved. One of the problems is the paucity of data on the in-vivo tissue compliance properties needed to generate acceptable output forces.(More)
For surgical training and preparations, the existing surgical virtual environments have shown great improvement. However, these improvements are more in the visual aspect. The incorporation of haptics into virtual reality base surgical simulations would enhance the sense of realism greatly. To aid in the development of the haptic surgical virtual(More)
