We have assembled a bi-manual telemanipulator capable of delicate operations. Each robotic arm has eight degrees of freedom which enables free manipulation via trocar kinematics. In addition minimally invasive instruments were equipped with strain gauge force sensors that can measure forces along three translational directions of the instrument's shaft. Forces are displayed to the user by means of two haptic devices which are also used for input. An endoscopic stereo-camera provides pictures from the region of operation to the user. In order to emulate a stereoscopic impression, pictures can be displayed by means of either a head mounted display, a CRT-screen equipped with shutter technology or a 3D video projection. With this system we have assessed the quality of force feedback and we have performed typical operations known from cardiac surgery. We also have shown that it is possible to perform certain recurrent tasks (like knot tying) automatically. Within this context we have implemented two application examples. In the first example a surgical knot is recorded and afterwards replayed with increased speed at the same position. The second example is the instantiation of a predefined knot at an arbitrary position.","PeriodicalId":119367,"journal":{"name":"18th IEEE Symposium on Computer-Based Medical Systems (CBMS'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129044549","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 rationale for the research is presented highlighting the obvious benefits of such an approach. A description of results obtained from an experiment seeking cardiac classification is presented. The dataset used contained 74 patient records; 30 inferior myocardial infarction and 44 normal. Patient records where acquired using 192-lead body surface potential maps (BSPM). QRS isointegral maps where derived from the 192 lead maps before applying principal component analysis to reduce the dimensionality of the dataset. Only the first 2 principal components were used to create a 2 dimensional space, which can be both easily visualized and modeled by a single perceptron. In addition to the optimised approach proposed, several other classification methods were evaluated on the dataset to generate benchmarks from which comparisons were made. These included linear, probabilistic, non-linear and neural network methods. The optimised approach resulted in sensitivity and specificity figures of 73.33% and 70.45% respectively and provided an overall accuracy which was 2.5% higher than that of the next best classifier.","PeriodicalId":119367,"journal":{"name":"18th IEEE Symposium on Computer-Based Medical Systems (CBMS'05)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114916681","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}
