  2. 1. THE ROLE OF VISUAL-SPATIAL ABILITY AND WORKING MEMORY IN IMAGE GUIDED SIMULATOR PERFORMANCE

    Author : Pehr Andersson; Greg Neely; Håkan Alm; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Numerous studies have analyzed the critical factors for training in surgical endoscopy to ensure high performance and increased patient safety. There are, however, surprisingly few studies that focus on the role of cognitive abilities, especially considering the fact that an estimated 50% of allmedical errors that lead to permanent disability and death are the result of cognitive failures (Gawande, Zinner, Studdert & Biennen, 2003).

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

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

    Abstract : 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. READ MORE

  5. 3. Simulation supported training in oral radiology : methods and impact on interpretative skill

    Author : Tore Nilsson; Jan Ahlqvist; Martin Rydmark; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virtual reality; simulation; simulator; radiology; radiography; learning; skill acquisition; visual-spatial ability; parallax; Radiology; Radiologi; odontologi; Odontology;

    Abstract : Simulation is an important tool when training is hazardous, time consuming, or expensive. Simulation can also be used to enhance reality by adding features normally not available in the real world. READ MORE

  6. 4. The next level : video gaming, cognition and motivation in surgical simulator training

    Author : Marcus Schlickum; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Image guided surgery uses small incisions or existing entry ports of the body in order to decrease surgical trauma which will hopefully lead to less infections, complications and number of days needed in the hospital. It is associated with great difficulties and a steep learning curve due to several reasons such as inverted movements and 2D representation of the operating area. READ MORE

  7. 5. Analysis of regional atrophy on brain imaging compared with cognitive function in the elderly and in patients with dementia – cross-sectional and longitudinal evaluation

    Author : Vilma Velickaite; Elna-Marie Larsson; Eric Westman; Lena Kilander; Kathinka Kurz; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dementia; Brain Imaging; Visual rating; Volumetry; Cognition;

    Abstract : During aging, brain changes are not homogeneous throughout the entire brain, but are related to changes in the morphology of neurons, as well as to changes in the tissue density, and are specific to each region of the brain. Dementia is a broad category of brain disorders with a set of symptoms including memory, visual-spatial and language problems. READ MORE
