The effect of the shock waves reflection on the collapse of a bubble near bone tissue. The 10 μm bubble is located 10.5 μm from the bone interface. (a) The reflected shock wave is implemented as a downwards traveling wave 0.54 amplitude of the original lithotripter shock wave after it hits the bone interface. The corresponding time for each bubble shape (from outer to inner) is 0, 0.123, 0.137, 0.142, 0.146, and 0.148 μs. (b) Simulation results without shock wave reflection. The bubble collapses only at 0.166 μs. For the dotted line bubble shapes, time from outer to inner are 0.154, 0.160, 0.166 μs
