Fig. 2From: Theoretically proposed optimal frequency for ultrasound induced cartilage restorationUltrasound induced cellular deformation, the color represents displacement in nanometers. The frequency and pressure amplitude was varied a) 1Â MHz; 14Â kPa, b) 5Â MHz; 14Â kPa, c) 6.5Â MHz; 14Â kPa, d) 1Â MHz; 170Â kPa, e) 5Â MHz; 170Â kPa, f) 6.5Â MHz; 170Â kPa. (The knobby appearances in A and D are exaggerated to visually see the displacement. The displacement magnitude is depicted by color and is not depicted to scale in the figures)Back to article page
