BACKGROUND AND PURPOSE Lesion volume change (LVC) assessment is essential in monitoring MS progression. LVC is usually measured by independently segmenting serial MR imaging examinations. Subtraction imaging has been proposed for improved visualization and characterization of lesion change. We compare segmentation of subtraction images (SSEG) with serial(More)
BACKGROUND AND PURPOSE While brain MR imaging is routinely performed, the MR imaging assessment of spinal cord pathology in multiple sclerosis (MS) is less frequent in clinical practice. The purpose of this study was to determine whether measurements of medulla oblongata volume (MOV) on routine brain MR imaging could serve as a biomarker of spinal cord(More)
The rise in the ubiquity of wireless internet access and handheld computing devices has opened several avenues for Location-Based and Location-Aware applications. Our work introduces an adaptation of a notification system based on Location-centric events and features. Real-time information can be used in order to increase a users' comprehension of his(More)
The needs of individuals with limited mobility have not been given as much importance as those of other users of internet-accessible mobile devices. Disabled users have information and service needs that are unique and a timely delivery of these services and information can be invaluable. This has motivated us toward the development of VTAssist, an(More)
When a person visits a place, it is almost always simple to understand the physical environment around them. Often people ignore---or don't have access to---the fourth dimension: time. Our research is an attempt to create a system that adds the aspect of time into location-based notification systems. This allows a person to not only experience their(More)
Finding resources in an indoor facility can be a difficult task, especially for patrons who are not familiar with what the facility has to offer. Current methods of indoor navigation involve the use of static maps, directions posted on walls and other traditional systems. However, as we see greater mobility of always-connected computing devices, we believe(More)
Information fragmentation is the problem of having a user's data tied to different formats, distributed across multiple locations, manipulated by different applications, and residing in a generally disconnected manner. In this paper, we take a closer look at the problem and describe the design of a framework that addresses information fragmentation of(More)
BACKGROUND AND PURPOSE The different clinical subtypes of multiple sclerosis (MS) may reflect underlying differences in affected neuroanatomic regions. Our aim was to analyze the effectiveness of jointly using the inferior subolivary medulla oblongata volume (MOV) and the cross-sectional area of the corpus callosum in distinguishing patients with(More)
An emerging challenge in the design of interfaces for mobile devices is the appropriate use of information about the location of the user. This chapter considers tradeoffs in privacy, computing power, memory capacity, and wireless signal availability that accompany the obtaining and use of location information and other contextual information in the design(More)
With an ever-increasing dominance of the Internet as the conduit for social, commercial, governance, and research activity; determining the physical location of end points is critical. Physical location is an essential piece of context that informs decision-systems of numerous geo-derived dimensions. For example, the location of a user performing an(More)
