Results from both computer simulations and real applications show that the adaptive spectral analysis method is more accurate in the detection of gastric dysrhythmia with brief duration, whereas STFT method is more appropriate for the estimation of signal amplitude. The performance of the ED method appears to be in between the STFT method and adaptive spectral analysis method.","PeriodicalId":344622,"journal":{"name":"Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124003875","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 the program is to provide early defection of infection or rejection so that therapeutic intervention can be instituted at the earliest sign of potential clinical problems. This study reports on the early detection capability of the home monitoring program, focusing on example cases of chronic rejection (OB) and infection (CMV). Declines in spirometry and increases in respiratory symptoms appeared in the home data 30-90 days before infection or rejection diagnoses were made in clinic. Thus home monitoring can provide a method for the early detection of infection or rejection after lung transplantation.<<ETX>>","PeriodicalId":344622,"journal":{"name":"Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114994536","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 interaction with images is generally personal, subjective, and limited to some degree by geography. Given the nature of the diagnostic process and the medical impact of an incorrect assessment, improvements in it might be realized if the process were less subjective and open to multiple viewers. Digital computer networks transcend many of the barriers associated with analog modes of communication, but while the technology continues to evolve, significant obstacles persist which prevent individuals located at disparate imaging facilities from interacting effectively. Particularly problematic in this regard is the fact that there are presently no true standards regarding the architecture, operating system, and graphic user interface (GUI) of interacting machines. The authors' goal was to develop an inexpensive means by which digital information and computer resources could be shared among distant clinical and research facilities irrespective of these parameters. They present a prototypic network of heterogeneous computer architectures which has been configured to assist investigators located at remote sites to archive, display, manipulate and share medical information such as health-related images and clinical reports. Since the inception of the network in November, 1994, the network has managed more than one thousand interactive imaging sessions and its medical databases are accessed at a rate of more than 300 queries/day by users around the globe. The network is presently being evaluated by a consortium of imaging sites throughout the health care community to explore its potential role in broader range digital consultation and distance learning applications.","PeriodicalId":344622,"journal":{"name":"Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130686725","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}

Although auto-skin graft after necrotic tissue removal (debridement) is the only way to save a burned patient, the procedure of the debridement has not been well-established. The authors have an idea to use excimer laser ablation for debridement. Since the burn eschar may have a high protein concentration with less water content compared with normal skin, the use of the excimer laser irradiation may induce efficient ablation. The authors found that the burn eschar can be eliminate efficiently with a sufficient ablation selectivity from normal skin using a KrF excimer laser (/spl lambda/=248 nm). In order to develop and attain fast and wide area elimination of burn eschar, the authors designed a manipulator for laser delivery. They think this new equipment might be useful for the treatment of burned patients.","PeriodicalId":344622,"journal":{"name":"Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121345493","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 some cases of heart failure the authors could see remarkable and very low-frequency oscillations of the Wigner-Ville distribution, which are related to Cheyne-Stokes respiration. However the Wigner-Ville distribution of normal subjects did not have such oscillations, but more random spectral characteristics instead. Furthermore, the authors calculated 1/f/sup /spl alpha// regression slopes of average spectrum to be a crude estimate of fractal dimensions. The slopes are more negative in heart failure patients than normals (-1.866/spl plusmn/0.888 vs. -0.957/spl plusmn/0.180 p<0.005), which associates a loss of dimensionality of heart rate fluctuation in heart failure.","PeriodicalId":344622,"journal":{"name":"Proceedings of 16th Annual International Conference of the IEEE Engineering in Medicine and Biology Society","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133352428","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}
