Molecular Imaging: Ultrasound
Ultrasound can be termed as cyclic pressurized sound having a frequency that is more than what human can hear. However, the frequency varies from one person to another, but usually it lies in range of 20 KHz in case of young adults. This frequency is often used as lower limit in describing the frequency of ultrasound. Ultrasound has many applications in different fields and is typically used when a medium needs to be penetrated. Measurement is done by the amount of reflected sound. This reflected sound is useful in detection of medium.
Among widely known applications of ultrasound is sonography. With use of ultrasound, one can produce the pictures of human foetus in the womb of mother. This is also known as medical imaging. Ultrasound is used as diagnostic tool in the field of medical imaging and one can visualize tendons, muscles and even many organs along with structure, size. Ultrasound is useful in producing real time images.
Ultrasound is powerful tool when one has to deal with emergencies as one gets to know the health state of foetus immediately. People who performs ultrasound scan are known as sonographers. Ultrasound is useful in conformation of foetal viability, can check for presence of physical abnormalities in human, can predict date of pregnancy, location of foetus attachment with cervix, can measure the heartbeat of foetus along with its movement, useful in accessing growth of foetus, and can detect the number of foetuses present in womb.
