Title: Narcolepsy – Exploratory Analysis

Abstract: Narcolepsy is a chronic neurological condition that results from the dysregulation of the sleep-wake cycle occurring in an early stage, specifically in adolescence. Although Narcolepsy occurs in an early stage there is a delay in diagnosis due to multiple reasons such as lack of symptom recognition, misdiagnoses as some of the symptoms overlap with other disorders like epilepsy, depression, insomnia to name a few. As a result of delayed diagnosis, the overall quality of life of a patient is affected.
The symptom pentad of narcolepsy includes excessive daytime sleepiness, cataplexy, hypnagogic hallucinations, sleep paralysis and disturbed nocturnal sleep. However, the symptoms related to narcolepsy are not limited to the pentad and cover a broad range covering symptoms not directly related to sleep, like, increase in weight, binge eating, anxiety, agitation. In order to reduce the delay in diagnosis, apart from having and creating an awareness about narcolepsy and it’s symptoms, it is important to look beyond the symptom pentad and understand the occurrences and interrelationships between these symptoms. Hence, this project aims at performing an exploratory analysis by looking into 20 symptoms, to understand symptom occurrences, the associations between symptoms to
name a few.

Title: Using Augmented Reality to assist in Medical Interventions

Abstract: Augmented Reality (AR) is an upcoming technique which can be used to display images overlaid on the normal vision of the user, several systems are on the market, in this project a Microsoft HoloLens will be used. A possible use of this technology is during medical interventions, allowing a surgeon to see displayed images inside a patient during surgery. If used as guidance a high accuracy of displayed projections is required to prevent damaging tissue. Previous work uses external tracking systems to enable accurate projections, using these systems is however not always possible, therefore this project will only use the hardware on a HoloLens. Previous research has shown that the spatial tracking of the HoloLens is not accurate, markers will, therefore, be used to track positions. The goal is to display a projection based on a CT image of a patient in the corresponding position inside the patient and report how accurate this projection is.
