A Collaborative VolumeViewer

This study has been carried out as a part of the EC funded project, SMARTDOC IST-2000-28137, with the objective of developing application components that provide highly interactive visualization and collaboration functionalities. The low-level components from the graphics library AVS OpenViz 2.0 are used as the development basis. The application components can be inserted into electronic documents that allow embedded controls such as web documents or Microsoft Word or PowerPoint documents. Instead of displaying results as static images, a SMARTDOC component provides the ability to visualize data and interact with it inside the document. Although the principal goal of the SMARTDOC project is to create components in a number of different application domains this study concentrates on developing a Medical imaging application component in collaboration with the project partners AETmed and professor Alan Jackson at the University of Manchester.

Kan strålar av ljus tyda det förflutna? : Användning av Reflectance Transformation Imaging (RTI) för att tyda runinskrifter på Pireus-lejonet

This paper deals with testing the method Reflectance Transformation Imaging (RTI) on the copy of the Piraeus-lion in Historic Museum in Stockholm. The purpose is to find out if it is possible to gather more information about the runic inscriptions. RTI is a method that records the surface normal of individual pixels in a digital photograph by analyzing the impact of light coming from different angles of entrance. RTI produces sort of a 3D-image of the object. There will be an overview of earlier interpretations of the runic scripts written on the lion as well as an overview of Varangians in the southeast.

En analys av forskningsfronten inom medicinsk etik

The purpose of this Masters thesis is to analyze the research front within medical ethics. We wish to identify which research themes that are included in the subject field of medical ethics. The research themes can be identified by a couple of bibliometrical methods and techniques. In our case, it is bibliographic coupling combined with a cluster analysis. The analysis is accomplished by the extracted references from articles in the two journals Bioethics and Journal of medical ethics.

Kaizen i praktiken inom Primärvården

The aim of the study was to support the ongoing kaizen work at a medical centre. Two main topics have been addressed in this study:? Find a solution to ensure that the kaizen decisions are followed and will get a strong grip in the organisation.? Support the kaizen process by giving advice on how to structure the meetingsand how the kaizen work could be done more effectively.The study started with a visit to the medical centre to observe the kaizen process and the attitudes among the employees. The employees were asked to fill in a survey about the kaizen work at the centre. The final recommendations given have been based on this and also information gathered from other medical centres which work after the same kaizen principles.

Är det mänskligt att fela? Synen på misstag och disciplinpåföljder i militär flygverksamhet och i hälso- och sjukvårdens verksamhet.

In the essay, the view of mistakes and disciplinary sanctions within the military aviation and health and medical service, are compared. The comparison shows that military aviation and health and medical service could have several points in common on how mistakes may occur, but that the present view of mistakes is different betwen the sectors. The view of mistakes and disciplinary sanctions is explicit within military aviation, and is based on a clear ideology on how mistakes occur, which is characterised of a systematic approach. Within health and medical service, an explicit and unequivocal ideology on how mistakes occur is missing, but, however, there are implicit ideas about infallibility and perfection. The comparison indicates that the view of mistakes is also, possibly directed by a bureaucratic model (instead of an ideology on mistakes), which aims to legitimacy, but that this may happen on the expense of not taking surrounding circumstances into consideration.

Visualisering av basalcellscancer med Tissue Viability Imaging - ett icke-invasivt diagnostiskt alternativ

Basal cell carcinoma (BCC) is the most common non-melanoma skin cancer. It can be divided in different subtypes. The most common type is superficial and is most frequently occurring on the trunk and on the face. In severe cases it can be difficult to differentiate basal cell carcinoma from other skin tumors, therefore a skin biopsy is conclusive diagnostic method. In terms of treatment, curettage is a common non-surgical treatment of basal cell carcinoma.

Patientinformation, vilken profession förmedlar den bäst? En systematisk litteraturstudie med tillhörande begreppsanalys.

This thesis is a systematic review of the Swedish healthcare and hospital-library?s authorities on the consumer health information. The goal is to evaluate the strengths and weaknesses that are inherited in two professions (medical and LiS) with two completely different perspectives on mediating information.The method used is a mix between conceptual analysis of the Swedish term ?patient information? and a Critical conceptual analysis, according to Fairclough, of published native theses and international professional journals.Conclusion of the thesis is that although the nursing and medical staff has the necessary medical expertise it does not, in many cases have either the time or skill to completely satisfy a patient or his/her next of kin´s information needs when exposed in a uneasy situation as when in need of treatment or help in any kind.The hospital librarian on the other hand does have the intermediating skills and most often the time to explain complex treatments or medical procedures, but the lack in medical or nursing expertise.In a perfect setting there is an inter-professional cooperation which brings a lot of positive results. The problem today is often to overcome the gap in awareness of one and other that exists in a modern Swedish hospital..
