    Ultrasound is a commonly used diagnostic imaging modality that involves the use of various frequencies of sound waves. The sound waves are created by means of the Piezoelectric effect, whereby an electrical current is induced through crystals on a transducer, causing them to produce mechanical vibrations which in turn generate ultrasonic sound waves. An image is produced when the waves are propagated through the body and reflected back towards the transducer. As a non-ionizing imaging tool, ultrasound

    Ultrasounds are an important feature of technology used in our world today. The medical world uses ultrasounds and x-rays on an everyday bases. Ultrasounds are high-frequency sound waves and ultrasounds also produce sound waves that are beamed into the body causing return echoes that are recorded to visualize structures beneath the skin. Ultrasounds have thousands of different types and help doctors and patients see specific diseases and conditions that they cannot see otherwise. However, even though

    What is Ultrasound? Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave

    INTRODUCTION Understanding the frank physics of ultrasound is vital for acute care physicians who present point-of-care ultrasound to make precise critical decisions. Ultrasound is made up of mechanical waves that can send across disparate materials like fluids, soft tissues and solids. It has a frequency higher than the higher human auditory check of 20 KHz.[1] Ultrasound frequency is described as the number of ultrasound waves each subsequent, and health ultrasound mechanisms use waves alongside a frequency

    the use of physics. Ultrasound is sound waves that have a frequency above human audible. (Ultrasound Physics and Instrument 111). With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues. As with audible sound waves, ultrasound waves must have a medium in which to travel and are subject to interference. In addition, much like light rays, they can be reflected, refracted, and focused. In general, ultrasound waves produced by

    As an ultrasound technician/sonographer I will have the ability to see dangerous defects within the human anatomy and begin a lifelong profession with many benefits. The Ultrasound was first invented in the early 1900’s and was surprisingly not used to produce photos of a fetus. In 1917 Paul Langen a marine life scientist used a form of ultrasound equipment in his attempt to detect submarines. After many failed attempts at using high frequency sound waves Dr. Ian Donald and his team in Glasgow, Scotland

    Ultrasounds also known as ultrasonography is an imaging technique that uses high-frequency sound waves to make pictures of structures that bounce off internal body parts to create images for medical purposes. This high pitch frequency cannot be heard by the human ear. Over the years, these noninvasive procedures for the most part have replaced the invasive surgery. These procedures cause the patient less trauma and a lower risk of complications that could arise from the alternative surgery. Most

    INTRODUCTION Ultrasound represents sound waves with frequencies greater than 16 kHz, higher than that could be heard by human. The upper limit of ultrasonic frequency is usually taken to be 5 MHz for gases and 500 MHz for liquids and solids [1] while the lower frequency limit is considered to be 20 kHz [2]. Ultrasound waves may be divided into two main areas [1, 3], Low Amplitude i.e. the propagation relates to the effect of medium on wave and High Amplitude in which the propagation is due to the
