Ultrasound Calculations

The table provides the data for the acoustic impedance and absorption coefficients for muscle and bone. A parallel beam of ultrasound of intensity  enters the muscle of thickness 3.0 cm as shown. The ultrasound...

Types of Ultrasound Scans

We will investigate two types of ultrasound scans. A-Scan This is a simple type of scan. A pulse of ultrasound is sent into the tissue and the echoes are detected to determine the depth...

Ultrasound Intensity Reflection and Attenuation

Intensity Reflection Coefficient When a beam of ultrasound is directed into a body, a certain proportion of the initial intensity would be reflected at the boundary. The ratio of the reflected intensity to the...

Using Ultrasound for Medical Imaging

In medical imaging, ultrasound is used mainly to detect the shape of a foetus. Ultrasound is also used for imaging the internal of a body. Since the wavelength of an ultrasound is in the...

Ultrasonic Production and Detection

Production Sound is created when a surface vibrates, pushing the medium particles into a series of compressions and rarefactions. A human being would normally be able to hear sound with frequency between 20 Hz...
