UltrasoUnd Physics & instrUmentation - Pegasus Lectures

dedication
This book is dedicated to my wife Carol, my mother Graziella, my three-year-old daughter Gina Luisa, my
twenty-month-old daughter Cristiana Graziella, and in loving memory of my grandmother Gina Luisa: four
generations of women who have shaped my life.
Of course I cannot forget my twenty-month-old son Franco Raffaello whose hugs redefine affection, or
my eldest son Paul (forever Paulie to me), who loves to sit in on lectures and “help out.” Finally, I must
acknowledge my father Frank, whose tireless work and selflessness afforded me educational opportunities
for which I feel blessed.
