In conjunction, human-generated clinical data are produced by clinicians providing care for those patients. Currently, physiological information is displayed in a limited univariate method, inherited from conventional practices of biomedical engineering firms who design and manufacture these medical devices. However, the method in which this information is displayed was developed with limited consideration from user-centered design practices, and largely excludes influential relationship to their underlying medical knowledge and experience. Moreover, these univariate displays have limited abilities to project trends. This paper proposes a framework for displaying multi-dimensional and complex data to users in the critical care environment. We present a case study of neonatal intensive care, a form of critical care for premature and ill term infants to illustrate the framework's practical impact.","PeriodicalId":398710,"journal":{"name":"2014 IEEE 27th International Symposium on Computer-Based Medical Systems","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125191947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we present the results of a subjective quality assessment study with 37 medical experts. We identify appropriate encoding configurations for the H.264 AVC coding standard to guarantee a visually loss less quality with a significant bitrate reduction. Further, we show that it is not necessary to capture the highest possible quality for documentation and retrospective analysis. A lower technical quality with a substantially lower bitrate still provides sufficient semantic quality. We finally present basic recommendations for an efficient encoding strategy with an appropriate tradeoff between visual quality and bitrate.","PeriodicalId":398710,"journal":{"name":"2014 IEEE 27th International Symposium on Computer-Based Medical Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129452106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this work is to provide to specialists a simple and flexible system that allows the extraction of quantitative synthetic parameters in time and frequency domain from EMG signals, in particular we propose a novel EMG data acquisition and processing system, referred as EMG-Miner, that allows the automated acquisition and analysis of EMG signals along the different stages of the rehabilitation process (follow-up) of a patient.","PeriodicalId":398710,"journal":{"name":"2014 IEEE 27th International Symposium on Computer-Based Medical Systems","volume":"35 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122600216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a method of simulating the deformation of three-dimensional objects that represent human organs through multiple layers of tissue, which utilizes the following physical parameters: modulus of elasticity, thickness and density. The number of layers and the allocation of physical parameters can be set according to the different tissues that make up the human body and the behavior to be simulated. Thus, it is possible to achieve visual realism, realistic haptics and real-time interaction, with acceptable computational cost. For the simulation of medical procedures, both visual realism and haptic technology are required in order to provide the user with sensations similar to those found in real procedures. The organ chosen for the experiments was the breast, and the results obtained in relation to the physical behavior of deformation were acceptable in relation to visual realism and haptics.","PeriodicalId":398710,"journal":{"name":"2014 IEEE 27th International Symposium on Computer-Based Medical Systems","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115153945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most often, the presented data cannot be collected and used as a whole to aid the decision making by availability and comparison of all relevant data at once. In this paper, a novel approach for handling real-time clinical data is presented. We developed TICoMS (Tübinger ICU Control and Monitoring System), a framework for integration of sensors and effectors into a homogeneous message-based network capable of gathering and distributing real-time data in ICU settings from medical devices. The accumulated data can be presented on a central patient monitoring screen for a fast and extensive overview of the patient's current condition and trends with a homogenous time-base. Furthermore, this framework provides control capabilities for medical devices and is therefore an essential foundation for device interactions that may allow for computer-based support in decision-making or advanced automation in intensive care scenarios.","PeriodicalId":398710,"journal":{"name":"2014 IEEE 27th International Symposium on Computer-Based Medical Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133053583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the emerging complex puzzle of the diversity of training needs for the aforementioned trainee group, consisting of a mixture of formal and informal careers, calls for a careful and perhaps more radical than the usually attempted approach. To this extent, this paper describes elements of the innovative efforts followed upon the training design of the DISCOVER EU project. Specifically, simulations of virtual patients in Second Life are exploited in conjunction with educational components and objects in semantically extended e-learning environments, in an attempt to make more realistic everyday training cases and diverse topic, content rich approaches. The whole endeavor is presented in view of the existing limitations to elderly careers' training and is soon to lend itself to a rigorous pilot phase in Greece. Planned evaluation sessions are envisaged to certify successes, to inform for any required improvements but also to identify pitfalls.","PeriodicalId":398710,"journal":{"name":"2014 IEEE 27th International Symposium on Computer-Based Medical Systems","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129080465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
