Thyroid region segmentation and volume estimation is a prerequisite step to diagnosing the pathology of the thyroid gland. In this study, a progressive learning vector quantization neural network (PLVQNN) combined with a preprocessing procedure is proposed for automatic thyroid segmentation and volume estimation using computerized tomography (CT) images. The preprocessing procedure is used to extract...
In order to investigate the validity of bypassing treatment for aortic dissection, two-dimensional idealized geometry models of DeBakey III aortic dissection and its bypassing treatment were constructed. Computational simulations of physiological blood flow in these models were performed with the software of ANSYS using finite element method. After bypassing treatment, the blood flow velocity and...
Hyperthyroidism is a common thyroid disease. Graves' disease is the most common etiology with 70-80% of hyperthyroidism. Conventionally, a diagnosis requires weeks to confirm with blood tests. In this paper, we proposed a novel approach to diagnose Gravespsila disease in ultrasound images directly. We segment the thyroid regions, and utilize a high performance classifier to recognize the regions....
Prostate hyperplasia is usually found affecting male adults in developed countries. Transrectal ultrasoundgraphy (TRUS) imaging is widely used to diagnose prostate disease. Ultrasonic images are often argued with their primitive echo perturbations and speckle noise, which may confuse the physicians in inspection. Therefore, in this paper, we propose an automatic prostate segmentation system in TRUS...
A novel wayfinding system is presented with an aim to increase workplace and life independence for cognitive-impaired patients such as people with traumatic brain injury, cerebral palsy, mental retardation, schizophrenia, and Alzheimer's disease. According to psychological model of spatial navigation and the requirements of rehabilitation professionals, PDA prompting with navigation video at the right...
A lymph node (LN), which can resist virus and germs, is part of the lymphatic system that exists in the human body and every apparatus inside it. There are many kinds of pathological changes in LN. Metastatic is one of the important indexes to estimate the stage of malignant tumors. One convenient tool to observe LN is the use olf ultrasonic images. Clinical physicians judge a nosology by biopsy and...
