Ultrasound Image Enhancement Using Particle Swarm Optimization

Ultrasound is sound waves with frequencies above the range of human hearing. Thus ultrasound may be defined as sound waves with frequencies exceeding 20000 hertz. Ultrasound wavelengths are shorter when compared to normal sound waves. Because of this the ultrasound waves are reflected back by obstacles in their path rather than bending round them and move forward. This quality of ultrasound makes it useful in many different fields including medical field.
