Providing semantic interoperability is a current challenge in the field of data integration. In healthcare environments, sharing information may be essential to ensure a good treatment to the patient. In addition, it is necessary to ensure the accuracy of the data that is being exchanged. In this paper we present the design and implementation of an ontology for the patient clinical evolution record,...
The research on Content-Based Image Retrieval (CBIR) is growing in relevance at a fast pace. Algorithms and tools for CBIR can help decision-making processes, for example allowing the specialist to retrieve cases similar to the one under evaluation. However, the main reservation about using CBIR is the semantic gap, which is the divergence among automatic results and what the user is expecting. We...
The purpose of the present work was to create a computational framework for radiological registry and diagnosis, which, by means of a nonintrusive approach, allows the users freedom annotation while storing related information in a structured and standard format. To get this goal, this work started with the investigation of lexical and semantic domain of radiological texts, followed by the design...
Functional magnetic resonance imaging (fMRI) has been applied with several purposes in clinical environment as well as in basic neuroscience studies. The main purpose of fMRI is to map brain activity, which is achieved by applying statistical methods to time series of each voxel intensity, related to changes in blood oxygen level, in response to a short stimulus. In this work, we propose a new method...
