Acoustic, texture, and morphological features of the breast in ultrasound imaging were extracted for computer-aided diagnosis. In addition, correlations among different categories of features were analyzed. Clinical data from 14 patients (7 malignant and 7 benign samples) were acquired. A custom-made setup was used for simultaneous data acquisition of B-mode ultrasound and limited-angle tomography...
Developmental dysplasia of the hip (DDH) is a congenital hip joint malformation affecting the proximal femurs and acetabulum that are subluxatable, dislocatable, and dislocated. DDH is best treated during infancy. In this paper, we designed and implemented a computer aided system for treatment of this disease. In this system, we used a mixture-based PV partial-volume algorithm to perform bone segmentation...
Tumor volume measurement on small animals is important but currently invasive. We employ ultrasonic micro-imaging (UMI) in this study and demonstrate its feasibility. In addition, we use small animal positron emission tomography (microPET) as a preliminary effort to develop multi-modality small animal imaging techniques. The tumor growth curve from UMI is also compared to radioactivity from microPET...
