A New Feature Ensemble with a Multistage Classification Scheme for Breast Cancer Diagnosis.

A new and effective feature ensemble with a multistage classification is proposed to be implemented in a computer-aided diagnosis (CAD) system for breast cancer diagnosis. A publicly available mammogram image dataset collected during the Image Retrieval in Medical Applications (IRMA) project is utilized to verify the suggested feature ensemble and multistage classification. In achieving the CAD system, feature extraction is performed on the mammogram region of interest (ROI) images which are preprocessed by applying a histogram equalization followed by a nonlocal means filtering.

Simulation of fluid environment using a robotic orthosis on human lower extremity for therapeutic purposes.

Rehabilitation under water is a viable physical rehabilitation option, but it has some limitations in terms of adapting to needs of each patient. In addition, its facility requirements are relatively high. Simulating the fluid environment using a robotic system would enable therapists adjust various parameters so that the therapy is tailored to the patient's unique state.

Corneal topographic changes after four types of pterygium surgery.

Purpose: To evaluate effects of different pterygium surgeries on corneal topography.

Methods: Pre- and postoperative computerized videokeratography was performed on 120 eyes of 115 patients undergoing pterygium removal. Four techniques were used: bare sclera, excision with mitomycin C, limbal-conjunctival autograft, and conjunctival autograft.
