mechanism of luminal gain following IVL treatment is calcium fracture, without the need for high-pressure balloon dilatation; 2) IVL results in circumferential and longitudinal calcium fracture; and 3) IVL treatment improves vessel compliance and facilitates stent expansion in calcified coronary arteries....
Wavelet analysis involves the breaking up of a signal into shifted and scaled versions of the original (or mother) wavelet. The continuous wavelet transform is defined as the sum over time of the signal multiplied by scaled, shifted versions of the wavelet function:C(scale,position)=∫−∞∞...
