This thesis presents a photmetric stereo method based on the work of Schulze [35], who in turn extended the research of Schroeder et al. [33,34] In this approach, three different lightings are obtained by illuminating the object by three colored light sources (red, green and blue). A video of the subject is captured from the front, the back and the side. The single frames are then extracted from the viedo, which are used for the 3D reconstruction of the subject. The aim of this work was to improve the presented method of Schulze with real patient subjects by getting a better sphere calibration and changing some parameters in the patient processing. As the graphical interface was implemented for persons with a technical background, it has been changed to become also more convenient to use for non-technically oriented staff
Access, Handling and Visualization Tools for Multiple Data Types for Breast Cancer Decision Support
(2011)
Breast cancer is the most commonly diagnosed cancer among U.S women, besides skin cancer. More than 1 in 4 cancers among women are breast cancer. And though death rates have been decreasing since 1990, about 40,170 women in the U.S. were expected to die in 2009 from breast cancer. The progress of molecular profiling, in the last decade has revolutionized the understanding of cancer, but also introduced more complexity with new data such as gene expression, copy number variation, mutations and DNA methylation. These new data open up the possibility of differential diagnosis, much more precise prognosis as well as prediction of therapy response than any of the diagnostic tools that are available in the current practice. Additionally, epidemiological databases store clinically relevant information on hundreds of thousands of patients. However, with the abundance of all this information, clinicians will need new tools to access and visualize such data and use the information gained to treat new patients. The general problem will be to access, filter and analyze the data and then visualize them in a clinical context. This data ranges from clinico-pathological information, to molecular profiles from highthroughput genomic measurements and imaging data. Furthermore, data from patient populations is aggregated on epidemiological level and can be found under numerous clinical studies.
Medication reconciliation is defined by the American Society of Health- System Pharmacists (ASHP) and the American Pharmacists Association (AphA) as “the comprehensive evaluation of a patient’s medication regimen any time there is a change in therapy in an effort to avoid medication errors such as omissions, duplications, dosing errors or drug interactions, as well as to observe compliance and adherence patterns “. Medication reconciliation is very important to avoid medication errors but it is also a complex and time-consuming process. Medication histories, i.e. records of prescription, purchase, and refill sequences are considered to be a resource from which conclusions about medication reconciliation can be drawn. However, medication histories spread across diverse paper and electronic media may lack the required accuracy. By employing multiple electronic sources this thesis will evaluate if more accurate medication histories can be collected.
