Evaluation of virtual reality bronchoscopy as a learning and assessment tool.

BACKGROUND: Conventional training in bronchoscopy involves a trainee performing on a real patient under supervision. This method of training is not only expensive, but there is also potential for increased patient discomfort. Simulators permit the ...

Simulation in surgical training: educational issues and practical implications.

BACKGROUND: Surgical skills are required by a wide range of health care professionals. Tasks range from simple wound closure to highly complex diagnostic and therapeutic procedures. Technical expertise, although essential, is only one component of a ...

Phase estimation of visual evoked responses.

The phase of visual evoked responses (VERs) is one of the basic parameters in functional diagnostics of the visual system. A new method for phase estimation of VERs based on the observer model in system identification is introduced. Simulated data show ...

Sequential designs for phase III clinical trials incorporating treatment selection.

Most statistical methodology for phase III clinical trials focuses on the comparison of a single experimental treatment with a control. An increasing desire to reduce the time before regulatory approval of a new drug is sought has led to development of ...

The margin for error when releasing the high bar for dismounts.

In Mens Artistic Gymnastics the current trend in elite high bar dismounts is to perform two somersaults in an extended body shape with a number of twists. Two techniques have been identified in the backward giant circles leading up to release for these ...

Virtual reality: new method of teaching anorectal and pelvic floor anatomy.

PURPOSE: A clear understanding of the intricate spatial relationships among the structures of the pelvic floor, rectum, and anal canal is essential for the treatment of numerous pathologic conditions. Virtual-reality technology allows improved ...

Modeling the dynamic characteristics of pneumatic muscle.

A pneumatic muscle (PM) system was studied to determine whether a three-element model could describe its dynamics. As far as the authors are aware, this model has not been used to describe the dynamics of PM. A new phenomenological model consists of a ...

Generalized least-squares method applied to fMRI time series with empirically determined correlation matrix.

Functional magnetic resonance imaging (fMRI) time series analysis and statistical inferences about the effect of a cognitive task on the regional cerebral blood flow (rCBF) are largely based on the linear model. However, this method requires that the ...
