Research ArticleOpen accessIn the keywordsLess Biased Approach for Sandstone Pore SegmentationDaffa Abiyyu Murtadha Kurnia, Iman Herwidiana KartowisastroReservoir characterization is a fundamental process in estimating reserves within petroleum and hydrogeological systems, where the precise determination of pore space dictates the validity of fluid flow models. Although X-Ray Computerized Tomography (XRCT) has become the standard non-destructive evaluation method for visualizing the internal structure of rocks, the data interpretation process still faces challenges during the image segmentation stage. Conventional … …Journal of Computer Science, Vol. 22, Issue 6 · 15 Jun 2026 · 1,191 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSelf Organizing Map Cluster Approach for Wavelet Based Medical Image CompressionS. Sridevi, V. R. Vijayakumar, V. Sutha JebaKumariDigital medical powerful tools for diagnosis, treatment and surgery and plays a vital role in modern healthcare delivery. Large storage capacity is needed for storing these images and for transmitting them. This leads to the strong demand for digital medical image compression and reliable transmission. In this study, we have applied three compression methods to medical images. In all the … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 4 · 2 Jan 2013 · 7,422 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsContent Based Image Retrieval of Ultrasound Liver Diseases Based on Hybrid ApproachR. Suganya, S. RajaramProblem statement: In the past few years, immense improvement was obtained in the field of Content-Based Image Retrieval (CBIR). Nevertheless, existing systems still fail when applied to medical image databases. Simple feature-extraction algorithms that operate on the entire image for characterization of color, texture, or shape cannot be related to the descriptive semantics of medical knowledge that is extracted from … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 24 Mar 2012 · 7,643 accessesView PDF Cite

Case ReportOpen accessIn the abstractRound Pneumonia in Adults Masquerading as Bronchogenic CarcinomaChandan Kumar, Abhishek, Pal Satyajit Singh Athwal et al.Round pneumonia or coin pneumonia is a rare variant in adults, although it is very common in the pediatric age group patients. It can mimic as a pulmonary mass on imaging, which can lead to broad differential diagnosis or misguidance toward the conditions like bronchogenic carcinoma or other benign conditions which can lead to unnecessary diagnostic work up like computerized … …American Journal of Infectious Diseases, Vol. 14, Issue 4 · 7 Jan 2019 · 8,322 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiomimetic Finite Element Analysis Bone Modeling for Customized Hybrid Biological Prostheses DevelopmentAversa Raffaella, Florian Ion T. Petrescu, Relly Victoria V. Petrescu, Apicella AntonioThe human femur shows a high capacity to withstand external stresses and it is due to the mass distribution, morphology, and orthotropic behaviors of trabecular and cortical bone. Faithful modeling of the femur accounting for bone distribution and material orthotropic behavior is presented. The use of biofidel model is aimed to develop an "in silico" tool that could enable the … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 30 Nov 2016 · 8,980 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Assessment of the Electric Power Quality and Electrical Installation Impacts on Medical Electrical Equipment Operations at Health Care FacilitiesMário César Giacco Ramos, Carlos Márcio Vieira TahanProblem statement: Medical electrical equipments at health care facilities presented malfunction and wrong medical information due to poor electric power quality and to inadequate electrical Installations. Some equipment such as X-ray, computerized axial tomography and magnetic resonance imaging are considered as polluting ones due to their high amount of harmonics and voltage transients produced on the electrical power supply when … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,514 accessesView PDF Cite
