This paper presents a computer aided detection scheme on digital chest radiographs for pneumoconiosis screening. The scheme involves several medical image processing and analysis technologies, i.e. lung segmentation algorithm using the active shape model, image enhancement and features extraction from lung regions, feature down-selection by correlation(More)
This paper mainly introduces the late achievements of theories and methods for this technology. And we look into the future of them at the end of this paper. The main contents include direct volume CT and its fast algorithms, volume imaging for non-complete data, direct volume CT based on digital radiography and reverse geometry X-ray.
