This collection brings together the fundamental research in shock focussing and sonoluminescence. The authors report on their studies on shock focussing and related bubble dynamics, as well as their applications in medical science. The destructive action of cavitation bubbles collapsing near boundaries is treated with special reference to kidney stones, demonstrating the capacity of bubbles for causing damage to materials. It is also shown that the shock theory of sonoluminescence plays an important part, as do converging shock and thermal waves emanating from sonoluminescing gas bubbles and upscaling single-bubble sonoluminescence. The book also addresses the current status of shock measurement technique and correlated clinical findings. The interdisciplinary approach of this book makes it relevant for medical doctors, technical researchers of lithotripsy and gas dynamicists.
