Scintillator thickness is very important and can be readily changed in fabrication. With increasing thickness, there is a degradation of MTF with spatial blurring but improved conversion efficiency. This design trade-off should be optimized for visualization. Using quantitative experimental and techniques, we simulated three detector models, including a direct detector and two indirect detectors with different scintillator thickness and investigated their effects on visualization of stent and guidewire. Detection performance was improved with the increasing scintillator thickness, especially at low exposure. With an idealized MTF, a direct detector performed fared better for stent detection as compared to guide wire detection","PeriodicalId":114618,"journal":{"name":"2005 IEEE Engineering in Medicine and Biology 27th Annual Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128686162","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}

Wireless body area networks (WBANs) of intelligent sensors represent an emerging technology for system integration with great potentials for unobtrusive ambulatory health monitoring during extended periods of time. However, system designers will have to resolve a number of issues, such as severe limitations of sensor weight and size necessary to improve user's compliance, sensor resource constraints, intermittent availability of uplink connectivity, reliability of transmission, security, and interoperability of different platforms. We present current and emerging wireless technologies and developments in pervasive and mobile technologies that are vital for implementation of WBAN-based monitors and m-Health system integration. We emphasize the problem of reliable system operation with extremely low power consumption and discontinuous connectivity, which are typical for ambulatory monitoring","PeriodicalId":114618,"journal":{"name":"2005 IEEE Engineering in Medicine and Biology 27th Annual Conference","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116355003","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}

We obtain vocal-tract filter (VTF) estimates for the inverse filtering from sustained vowel sounds over closed glottal phases using a new method, which minimizes the effects of glottal waves on the VTF estimates. It is common that VTF estimates contain the effects of incomplete glottal closures, and the glottal waves obtained via inverse filtering contain residual vocal-tract resonance. Our simulations show that the residual resonance appears as stationary ripples superimposed on the derivatives of the original glottal waves over the duration of a glottal cycle. The VTF estimates and the glottal waves obtained from sustained vowel sounds /a/ produced by male and female subjects are presented. The derivatives of the obtained glottal waves exhibit transient positive peaks during vocal-fold collision and negative levels in the earlier stage of vocal-fold parting","PeriodicalId":114618,"journal":{"name":"2005 IEEE Engineering in Medicine and Biology 27th Annual Conference","volume":"279 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131822200","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}
