The complex processes can be quantitatively described by the mathematical model. Therefore, it is of great theoretical value and profound realistic significance to research on mathematical models of the purkinje cell, which consequently in depth elucidates the mechanism of the purkinje fiber clear in microcosmic fields. This template, With the rapid development of the computing technology , computational models of the single cell are increasingly widely used in the research on the heart in the biological field. The purkinje fibre is an important tissue in the heart, and it dominates receiving and conducting excitation. In addition, the excitation conduction of the ventricle is considered mainly deriving from the purkinje fibre. Therefore, besides theoretical significance, it has also application value to research on the purkinje fibre cell, even for the further study on the heart, by building mathematical models and reproducing the active procedure. In this paper, the purkinje fibre and some relevant concepts are introduced first, and then two typical models of the purkinje fibre cell are focused on, especially their mechnisms, features and the simulations. At last the future research strategies and trends are discussed.","PeriodicalId":6389,"journal":{"name":"2009 2nd International Conference on Biomedical Engineering and Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84306801","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}

Cell image analysis, an assisting method of clinical information acquisition, has played an important role in facilitating the appropriate diagnosis and treatment against some serious diseases such as cancer, leukemia and etc. Early studies of this field focuses on still image information and mainly concerns either cell counting or the morphological characteristics of cell image. Furthermore, much effort has been devoted to analyzing the morphological change of cell image qualitatively, while less attention has been paid to analyzing it quantitatively which in fact is more effective, objective and accurate. Under this very circumstances, our work concentrates on analyzing the cellular morphological change by means of quantitative measurement, and a new method—circumference radial difference (Rdc )i s pro- posed. The basic idea is to measure the morphological change by estimating the radial differences from 360 different angles. Two sets of lymphocyte video database provided by the cooperation hospital are used to verify the proposed approach. Experimental results show that the proposed (Rdc) measurement can produce reasonably good agreement with subjective judgment by people.","PeriodicalId":6389,"journal":{"name":"2009 2nd International Conference on Biomedical Engineering and Informatics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85037211","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}
