    The need for systems that can store, represent and provide efficient retrieval facilities for images of particular interest is becoming very high in medicine. In this respect, a lot of work has been done to integrate image data in standard data processing environments. The two different approaches that are used for the representation of images are the meta-data and the content-based approaches. Us... View full abstract»

    This paper presents an environment for collecting clinical data using structured speech input. The system uses nomenclature terms and data consistency rules to limit the speech input to a discrete set of phrases which can be configured to support a wide range of studies. This information is stored in an event-oriented data model as strongly typed observations for subsequent distribution and data a... View full abstract»

    Describes several types of efficiency enhancements of "classical" rule-based diagnostic expert systems. The blackboard control structure enables one to explore more knowledge bases of the same syntax in parallel, the taxonomy structures make fast zooming of attention possible and provide an additional inference mechanism based on inheritance principles. In addition to these mechanisms, we describe... View full abstract»

    Diagnostics of hearing impairments is a non-trivial problem for data mining techniques. The state of hearing can be described via a measurement of polymorphic disorders in the voice structure that are secondary to restricted auditory control. The diagnostic voice analysis determines voice descriptors that can be used for marginal estimation of the state of hearing. This problem is hard for most of... View full abstract»

    Advances in telemedicine technology have led to intelligent monitoring systems that are capable of helping medical experts in their decision-making process. These systems imply the introduction of a bed-side computer that supervises the patient and collects, stores and visualizes all the information provided by the medical devices in an accessible way. This paper describes the telemedicine system ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (266 KB) | HTML iconHTML

    Ensembles of simple Bayesian classifiers have traditionally not been in the focus of classification research partly because of the stability of a simple Bayesian classifier and because of the rarely valid basic assumption that the classification features are independent of each other, given the predicted value. As a way to try to circumvent these problems we suggest the use of an ensemble of simpl... View full abstract»

    In this paper, we present some important aspects of software testing. We explain why software reliability is important, especially for medical software products. The automation of testing procedures is important in order to achieve the desired reliability level. For this purpose, intelligent systems can be used to identify potentially dangerous software modules. We present an evolutionary decision... View full abstract»

    The pulse waveform plays an important role in pulse diagnosis, which is the key technique in traditional Chinese medicine. However, its baseline wander introduced in the acquisition process will result in misdiagnosis. Therefore a wavelet based cascade adaptive filter to remove this wander is presented. This cascade adaptive filter works in two stages. The first stage is a discrete Meyer wavelet f... View full abstract»

    Modern and effective biomedical research needs new and effective methods. Use of 96-well micro-titre plates allows the performance of many experiments and samples under the same conditions. The methods used to determine cell numbers in these plates are all end-point methods. These methods allow only one determination per plate, and the cells are lost. Usually, such assays are performed according t... View full abstract»

    A novel autonomous evolutionary algorithm for the construction of decision trees is presented, together with an analysis of different medical data sets. The algorithm's capability to self-adapt to a given problem is used as a measure to predict if some data set is just difficult or whether it is impossible to analyze. If a specific data set doesn't include enough or proper information for the crea... View full abstract»

    Exceptional events in a time series are observations which can be regarded as qualitatively significant anomalies. The detection of such events is an interesting problem in several domains, in particular for the generation of alarms in clinical microbiology. We propose an approach to the detection of exceptional events based on model selection. For each mathematical form of a model, we choose the ... View full abstract»

    Searching for new rules and new knowledge in problem areas, where very little or almost none previous knowledge is present, can be a very long and demanding process. In our research we addressed the problem of finding new knowledge in the form of rules in the diabetes database using a combination of decision trees and association rules. The first question we wanted to answer was, if there are sign... View full abstract»

    Palliative care units are hospital services that assist advanced-state terminal patients. These patients are geographically distributed and some hospital tasks such as the organization of visits, the management of medicines, and the analysis of patients are difficult to manage. Here, a multi-layer computer system is proposed. The communication, information system, and multi-agent layers are descri... View full abstract»

    A method is presented to determine features of heart sounds. A wavelet transform is applied to a window of two periods of heart sounds. Two analyses are realized for the signals in the window: segmentation of the first and second heart sounds, and extraction of the features. After the segmentation, feature vectors are formed by using the wavelet detail coefficients at the sixth decomposition level... View full abstract»

    The increasing storage of vast amounts of information on computers and the rapidly increasing size of databases stored online has the population (and even many politicians) worried about invasion of privacy. This paper examines some possible ways in which privacy maybe invaded by the use of medical databases, particularly during the analysis and publication of results. View full abstract»

    Within the confines of a healthcare enterprise memory (HEM), most traditional medical systems do not sufficiently provide the necessary assistance to healthcare practitioners in the handling of critical situations. Furthermore, localized knowledge repositories often lack the required knowledge for problem solving. Therefore, in this paper, we present an agent-based knowledge broker called the Inte...
