Quantitative assessment of surface roughness using backscattered ultrasound: The effects of finite surface curvature
(Elsevier, 1994)
We have previously described a technique to quantify surface fibrillatory changes in osteoarthritic articular cartilage. In that study, the angular distribution of the scattered acoustic field from an insonifying source ...
HIV's evasion of the cellular immune response
