In this work, a 3D reconstruction process using simulated CT technique is developed and tested. The reconstruction principle of simulated CT Scan is similar to CT-scan based reconstruction technique, however the input data acquisition technique is different. Using this technique, a good reconstruction result can be achieved with higher angular resolution of the object projection image. Here, an electro-mechanic controlled rotary table system was designed and manufactured. This system was carefully designed to ensure that the image of X-ray scanned object was clearly taken without any interference. Furthermore, an intensity standardization method of the projection image has been developed. A cone beam algorithm has been employed to reconstruct the 3D solid model, which can be read by any commercial CAD software, where the geometrical analysis could then be conducted. The analysis results show a good agreement between the reconstructed and the original object, where the maximum difference is around 1.6 mm.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129069906","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}

Each spectral band has different characteristics according to the reflection level captured by hyperspectral remote sensor. These characteristics can distinguish a class with another classes in the hyperspecral image classification, however in some spectral bands these characteristics are not unique so these classes can't be separated perfectly. There are several factors that cause this to happen, e.g. atmospheric effects that can disrupt the reflection captured by the sensor and the natural similarity of several classes. So not all spectral bands have enough information that can separates each class in these spectral bands. Information that not evenly distributed throughout the spectral bands needed a weighting scheme that can provide suitable proportion of each spectral band in the hyperspectral image classification. This paper proposes method that implemented weighting scheme as an embedded feature selection on hyperspectral dataset provided by AVIRIS imaging spectometer. Three methods used to estimate spectral weight i.e. Gradient Descent, Mutual Information, and Bhattacharyya Distance. These 3 methods are integrated into SVM learning procedure through its kernel function, called weighted kernel, as weight estimator. From the experiments later in this paper, it can be seen that Gradient Descent outperforms two other methods but takes much time to be executed because it uses many iterations to achieve good performance.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115131470","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 objective of the study was to identify the parameters that influence, penetration depth in the teeth and to determine the suitable value of X-ray power in kV and current exposure time in mAs in order to produce high quality images by using X-ray imaging. Forty two teeth samples including 15 molars, 9 canines and 18 incisors were sectioned perpendicularly using CO2 laser radiations at wavelength 10.6μm at different power intensities of 10.11W, 10.13W, 11.36W, 11.83W, 12.39W and 13.40W for four different exposure time for 2, 3, 4 and 5 minutes. After being exposed to the CO2 laser beams, the teeth samples were then scanned using the X-ray imaging. From observations, the most suitable parameters for X-ray imaging were 40kV X-ray voltage and current exposure time at 5 mAs. The depth penetration for molar teeth was the least compared to that of the canines and incisors. The relationship between depth penetration and power of laser beam and exposure time were almost linear. As a conclusion, the depth penetration increased with increasing power of laser beam and exposure time. This study is important to identify the appropriate level of power for laser beam for imaging the teeth.","PeriodicalId":191194,"journal":{"name":"International Conference on Instrumentation, Communication, Information Technology, and Biomedical Engineering 2009","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127595167","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}
