Figure 1 Plot of the cyclic variation of integrated backscatter (cvIBS) sampled on the inferior base segment and the calibrated integrated backscatter (cIBS) in a four-year-old Duchenne muscular dystrophy (DMD) child (upper curve) and in an age-matched control (lower curve). The cvIBS and cIBS values are respectively smaller and higher in the DMD child than in the control.
