Noninvasive Medical Diagnostics & Treatment Using Ultrasonics

INTRODUCTION Noninvasive medical diagnostics and treatment tools are significantly increasing the pool of effective choices that are available to doctors and surgeons. Every part of the human body has already been explored with such tools and the reported success is very encouraging. With limited capability, visual and acoustic methods have been in use as diagnostic and NDT tools for hundreds of years. The introduction of such methods as radiography, MRI, magnetic field treatment and ultrasonics as well as computers and imaging devices made an innumerous impact on both fields. Ultrasound offers a wide range of possibilities and capabilities since the wave can be used in a broad frequency range, having variety of modes and can be operated in low and high power levels. Some of the most widely known applications are fetus imaging and kidney stones destruction. Medical ultrasonics offers safe, accurate and cost-effective tools, where no known health hazard is associated with its use at low power.
