Ultrasound imaging and Fine Needle Aspiration Biopsy, which used for diagnosis of thyroid cancer, don't ensure sufficient sensitivity and specificity. Due to this fact, many patients undergo unnecessary thyroid removal. In this study, it is aimed to find new features based on non-invasive Computerized Tomography. 52 nodular goiter patients who underwent thyroid removal surgery with suspicion of cancer...
Computed tomography is used nowadays for analyzing the problem in the human body and it plays a very important role in diagnosing defects in the patients. Computed tomography only became feasible with the development of computer signal processing capabilities. Technology is improved to capture the inner parts of the human body from 2D to 3D and also from 3D to 4D. A tomographic image is a cross sectional...
Lung cancer has become the foremost cause of high mortality rate in the western world. Subsequently, many image databases are being developed to enhance the investigation of nodules detection techniques in the early stages of lung cancer. Notably, Lung Image Database Consortium (LIDC) is widely recognized as one of the truthful databases but the efficient assessment of nodules on LIDC based Computed...
Lung segmentation operation is handling a very important role for determining unhealthy tissues and thus diagnosis and treatment of lung cancer. In this work Lung CT images are segmented by using Random Walk algorithm. First 25 DICOM images belong to 4 patients are read for processing and 8-bit gray level images obtained. For interactive segmentation, the seed points are set and applied as input parameters...
