Evaluation of INPRES--Intraoperative Presentation of surgical planning and simulation results.
In this paper we present fundamental results of the first evaluation of INPRES in a laboratory environment. While the system itself--an HMD-based approach for intraoperative augmented reality in head and neck surgery--has been described elsewhere several times, this paper will focus on methods and outcome of recently accomplished test procedures.

Quantifying expert vs. novice skill in vivo for development of a laryngoscopy simulator.
Many medical procedures require fine motor skills, and these skills are developed over years of practice and through performing hundreds to thousands of procedures. However medical training that is based upon gaining this expertise by performing procedures on patients results in unnecessary risk to the patient. In this project expert medical skill is quantified, so that advanced medical simulators can be created to provide a realistic training environment. ⋯ However, when two experts perform laryngoscopy on the same patient, both experts perform key elements of the task consistently. The measured consistency among experts indicates that it will be possible to apply algorithms developed for Human Skill Acquisition, and thereby define regions of expert motion relative to patient anatomy. This is the first step in developing advanced training simulators that will simulate the procedure accurately, provide guidance to the trainee, and can be used for assessment of medical skill.

The Arden Syntax is a simple syntax that allows physicians to encode medical knowledge in small modules, called medical logic modules (MLM). These MLM are well suited to data-driven alerts and reminders. ⋯ Our work proposes an environment that simulates various elements required by MLMs, allowing the students to execute the MLMs they have written immediately. This provides the necessary feedback to understand in depth the inner workings of MLMs.

Using mobile information technology to build a database for anesthesia quality control and to provide clinical guidelines.
The paper describes a mobile information system to collect patient information for anaesthesia quality control. In this system we use handheld computers, to collect patient data at the bedside with a daily synchronization of the data of the anaesthesiologist's handheld with the anaesthesia database center, later used for quality control analysis. Further, we design mobile clinical guidelines to be used on the same handhelds.

Online training evaluation in VR simulators using Gaussian Mixture Models.
A new approach to evaluate training in simulators based on virtual reality is proposed. This approach uses Gaussian Mixture Models (GMM) for modeling and classification of the simulation in pre-defined classes of training.
