The use of hybrid structural filtering for the detection ofobliterative bronchiolitis from computed tomographic images

摘要

Bronchiolar obstruction is commonly manifested in computedtomographic (CT) images as areas of decreased attenuation relative toadjacent normal lung parenchyma. The certain identification of suchareas is difficult in practice, particularly if such areas are poorlymarginated. This paper presents a novel approach to the enhancement offeature differences between normal and diseased lung parenchyma so thatreliable visual assessment can be made
