1. 16. Human factors in image guided surgical simulator training : components, visual-spatial and haptic aspects

   Författare :Pär Ström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Image guided surgery; virtual reality; simulation; simulator training; skill acquisition; performance; components; visual-spatial ability; haptic feedback;

   Sammanfattning : New image-guided surgical techniques such as arthroscopy and laparoscopy are difficult to learn and master. To handle these techniques, there seems to be a need for higher-level abilities such as visual-spatial abilities. LÄS MER

3. 17. Effective development of haptic devices using a model-based and simulation-driven design approach

   Författare :Aftab Ahmad; Kjell Andersson; Damien Chablat; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Haptic device; model-based design; design optimization;

   Sammanfattning : Virtual reality (VR)-based surgical simulators using haptic devices can increase the effectiveness of surgical training for surgeons when performing surgical procedures in hard tissues such as bones or teeth milling. The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device, which reflects the interaction with the virtual model. LÄS MER

4. 18. Is it all about the money? The effects of low and high cost simulator training scenarios in surgical training

   Författare :Ninos Oussi; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: The learning process is complex and dependent on several factors such as for instance, the environment to learn, prior knowledge and distinct abilities, motivation, goal-orientation as well as the effects of instructor feedback. Medical education, in particular within surgical domains is imperative due to its influence on patient safety. LÄS MER

5. 19. Model-based design of haptic devices

   Författare :Ahmad Aftab; Kjell Andersson; Ulf Sellgren; Per Wennhage; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Haptic device; model-based design; stiffness; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Efficient engineering design and development of high precision and reliable surgical simulators, like haptic devices for surgical training benefits from model-based and simulation driven design. The complexity of the design space, multi-domains, multicriteria requirements and multi-physics character of the behavior of such a product ask for a model based systematic approach for creating and validating compact and computationally efficient simulation models to be used for the design process.
