Computed Tomography (CT) patient scan data with a pelvic fracture was obtained in a Digital Imaging and Communications in Medicine (DICOM) format. Mimics software was used to process the data. Threshold and region of interest tools were used to prepare the three-dimensional (3D) digital model. Artefacts and noise distortions were removed manually before generating the 3D digital model. Then, the 3D digital model was converted to Standard Triangulation Language (STL) file. RP medical model was successfully produced using a Fused Deposition Modeling (FDM) machine. Measurement comparisons were done on the CT scan data, 3D digital model and FDM medical model. The FDM medical model was given to the orthopaedic surgeon for comments and feedback. This is an important step as surgeons play a crucial role in validating the RP medical model. The results obtained showed that the RP medical model has high accuracy rate as measurements were not significant compared to the CT scan and 3D digital model measurements. Therefore, RP can be integrated for medical applications.","PeriodicalId":241343,"journal":{"name":"2010 IEEE EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124055378","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}

These study include five different common threads profile of implant body - buttress, reverse buttress, V-shape, sinusoidal and square - that were evaluated via finite element analysis. Three dimensional model of a mandible was reconstructed from CT dataset and a region of interest was selected at the left side around the first molar. The mandible was separated into two types - compact cortical and porous cancellous. This will allow for proper load transfer to the mandible during simulation of the mastication process. A generic abutment model was virtually connected to the implant body, and a crown representing the first molar was placed onto the abutment. The motion of the implant body relative to the bone was calculated under occlusal load ranging from 10N to 200N applied to the crown. Result showed that the reverse buttress and V-shape thread offer high stability by provide less micromotion at the dental implant body.","PeriodicalId":241343,"journal":{"name":"2010 IEEE EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131757562","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}

One of the main tasks is the analyzing of white blood cells (WBC) where the WBC composition reveals important diagnostic information of a patient. This paper presents a two phase methodology in order to obtain a fully segmented abnormal white blood cell (blast) and nucleus in acute leukaemia images. In the first phase, the three contrast enhancement techniques which are partial contrast, bright stretching and dark stretching were used to improve the image quality. Contrast enhancement techniques enhanced the area of interest of acute leukaemia for easing the segmentation process. In the second phase, image segmentation based on HSI (Hue, Saturation, Intensity) colour space is proposed. The proposed technique helps to improve the image visibility and has successfully segmented the acute leukaemia images into two main components: blast and nucleus. The combination between contrast enhancements and image segmentation has good effect on improving the accuracy of segmentation. Hence, information gain from the resultant images would become useful for haematologists to further analysis the types of acute leukaemia.","PeriodicalId":241343,"journal":{"name":"2010 IEEE EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127654130","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}

It is important to diagnose asphyxia in infants as early as possible, as it could lead to infant morbidity. PCA has the capability to reduce the dimension of input feature vector to SVM. Previous attempts with PCA and SVM to detect asphyxia from baby cries found their principal components in a random manner, which consumes tremendous computation effort and time. Our work here investigates the improvement in performance to detect asphyxia from infant cries by integrating PCA and SVM with a polynomial kernel, with principal components being ranked by EOC, CPV and SCREE methods. Extracted features from the analysis of MFC coefficients are first ranked with the three feature selection algorithms of PCA, before being submitted to SVM for classification. Classification accuracy and support vector are employed to gauge the performance. It is found that the highest classification accuracy and support vector number from classification with support vector machine alone are 93.836% and 335.1, with a second order polynomial kernel and a regularization parameter of 1E-04, while those from CPV and SVM outperformed with CA of 94.172%, a low SV of 254.3, a third order polynomial and regularization parameter of 1E-05.","PeriodicalId":241343,"journal":{"name":"2010 IEEE EMBS Conference on Biomedical Engineering and Sciences (IECBES)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114587471","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}
