There has been a need since time immemorial for humankind to “see” disease in order to better understand it. Technologies that enabled the modern surgeon to “see” provided the impetus for the minimally invasive, laparoscopic revolution. Today, technologies that image disease in wavelengths other than that of visible light are available to guide the surgeon-interventionist. Of these technologies, ultrasound has the greatest potential to be of immediate benefit to surgeons of all disciplines who practice minimally invasive surgery.
