OBJECT Catheter-related infection of the cerebrospinal fluid (CSF) pathways is a potentially life-threatening complication of external ventricular drainage. A major source of infection is bacterial contamination along the external ventricular drain (EVD) catheter track. The authors examined the efficacy of EVD catheters impregnated with minocycline and(More)
Keywords: Fuzzy logic Knowledge elicitation Membership functions Minimally invasive surgery (MIS) Objective assessment Surgical training systems a b s t r a c t Effective training is the key to minimizing the dangers of minimally invasive surgery (MIS). At present, the assessment of laparoscopic skills relies on the expertise of senior surgeons. The(More)
BACKGROUND Surgeons performing laparoscopic surgery have strong biases regarding the quality and nature of the laparoscopic video monitor display. In a comparative study, we used a unique computerized sensing and analysis system to evaluate the various types of monitors employed in laparoscopic surgery. METHODS We compared the impact of different types of(More)
In this paper, a hybrid view application is proposed — a subsystem of a computerized laparoscopic surgery training system. To minimize the potential hazards of laparo-scopic surgery, an assistive training system is being developed. A digital camera and magnetic position sensors are used to detect laparoscopic instruments in the system. The hybrid view is a(More)
To provide appropriate guidance in minimally invasive surgical training (and potentially an additional safety measure in the operating room), we propose a model called a " No-Fly Zone " based on the situational awareness enhancing system. By defining the configuration space of the instrument, a collision free region is defined. If an intrusion occurs into(More)
Minimally invasive procedures are highly effective when performed by well trained surgeons. However, with the subjective nature of surgical training and performance assessment, it is difficult to determine when a trainee surgeon has attained a satisfactory level of competency. We propose a computer-based training and performance assessment system where we(More)
This paper describes a system developed to assist in model-based training of minimally invasive, laparoscopic procedures. The key factor motivating the development of the device called CAST (Computer-Assisted Surgical Trainer) is the need to improve the state-of-the-art in teaching laparoscopy, and ultimately achieve better surgical outcomes. CAST's design(More)
Ever more frequently business enterprises are benefiting from the collection and analysis of large data. This paper reports on a work in progress of adapting intelligence, predictive analyt-ics tools for analysis of medical data. While large data has been used in medical research, only recently has this become a trend for hospital management. A suite of(More)
