The main problems to be faced are related, from one point, to the high level of speckle noise and, from the other, to the need of an accurate segmentation of the vessel structure for diagnostic purposes. In particular, the detection of the intima layer plays a fundamental role as it represents the initial contour from where the method should start. We propose an automatic segmentation approach which makes use of a first non linear filtering based on anisotropic diffusion followed by an iterative relaxation procedure. Once the intima layer has been detected our method tries to locate an optimal initial contour to detect the wall of the artery by minimizing of a modified energy functional.","PeriodicalId":211161,"journal":{"name":"2007 IEEE International Workshop on Medical Measurement and Applications","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117171340","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}

Haptic interfaces have shown clear benefits in imitating therapists' exercises with the possibilities of position, grasping angles and force capturing. In this paper, we present two haptic-based virtual reality exercises for stroke patients undergoing rehabilitation to recover all, or some, of their lost hand functions. The two exercises, the squeeze ball exercise and the maze exercise, were implemented using the CyberForce system. The squeeze ball exercise helps patients recover the action of hand grasping whereas the maze exercise aims at increasing the steadiness of the patient's movement. Our measurements of these exercises show that we can continuously evaluate the patient's improvement.","PeriodicalId":211161,"journal":{"name":"2007 IEEE International Workshop on Medical Measurement and Applications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116726798","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 separation process of such signals as cardiac and respiratory BI components, is not a trivial filtering due to overlapping of spectra and non stationarity of these signals, and moreover, due to the infra-low frequency range. Therefore, advanced signal processing concepts and methods are needed to achieve the goal. The Signal-Shape Locked Loop (SSLL) concept was introduced to solve the task. Using this concept, it is possible to separate two (or more) independent signal components from the total input signal. Technical solution of the system is intended for applications in portable and implantable cardiac devices.","PeriodicalId":211161,"journal":{"name":"2007 IEEE International Workshop on Medical Measurement and Applications","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114774528","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}

Classical methods for dental acquisition do not give a fast, accurate and low cost solution. Moreover, orthognathic surgery requires accurate registration with CTscan images, which is difficult with state of the art systems, as dental fillings destroy the CT scan images. This paper presents an approach improving simulation and planning techniques by applying the laser triangulation technology in the field of maxillo-facial surgery or dental implants. The originality is found in the combination of the laser scanning technique with a specific double bite wafer and a rigid registration method. The scanner calibration, registration method and tests of impression material are presented, as well as a first validation.","PeriodicalId":211161,"journal":{"name":"2007 IEEE International Workshop on Medical Measurement and Applications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121828811","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}
