The designers using this process actively and continually drew upon the knowledge and experiences of people who will ultimately use the product. The outcome is a 'tool' that enables people in medical settings to perform a task previously unavailable to them, on-site real-time blood gas analysis. As a tool, the device needed to provide the functions in the most efficient and effective manner. To understand what product interface would be needed to accomplish this, potential end-users were involved throughout the design process. The paper focuses on this user-centered development process that literally brought the device into the hands of clinicians.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129696413","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 experimental results indicate that the proposed scheme achieves significantly higher compression compared to the other techniques considered.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132468523","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}

A SEPG's mission is to, 'provide leadership in advancing the state of the practice of software engineering to improve the quality of systems that depend on software'. The main method the SEPG uses is technology transition, 'the process of organizing, executing, and supporting activities that lead to the adoption and institutionalization of new technologies, methods, or approaches such that they become a routine part of doing business'.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117032761","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}

For example, the Therac 25 incident killed two patients and severely injured a third patient due to a software error. The Therac 25 is a computer-controlled therapeutic radiation machine. Governmental, industrial, and academic researchers are searching for new ways to prevent and detect hazardous faults when developing and certifying safety-critical software systems. To determine the effects of these new techniques, this paper discusses an experiment where developers in the control group followed a traditional methodology while the experimental group followed a modified methodology, which consisted of the control group's methodology along with certain safety-specific methods and guidelines for the following life-cycle phases: specification, design, and verification. The results showed that the experimental group had fewer latent safety-critical faults than the control group.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132541186","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}

By using this model and utilizing quadratic expression of an ellipse, the intensity distribution of an ellipse in any image plane, which is perpendicular to the plane of the arterial cross-section, is computed. A nonlinear parametric model for observed intensity distribution of an arterial cross-section is applied to estimate not only cross-sectional areas but also parameters of the ellipse which are essential in 3-D reconstruction of an arterial segment. This model takes into account background intensity, noise and blurring. Performance of this model has been tested on computer-generated and actual data for various background types and noise values and compared to those of other methods for estimating arterial dimensions. The computed cross-sectional areas from our model for computer-generated as well as actual data demonstrate much less variability than those reported in recent literature. 3-D reconstruction of arterial segments from actual biplane angiograms is presented.<<ETX>>","PeriodicalId":250310,"journal":{"name":"[1993] Computer-Based Medical Systems-Proceedings of the Sixth Annual IEEE Symposium","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122034818","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}
