Principles of Physics in Ultrasound Essay - 1717 Words

Principles of Physics in Ultrasound Physics has become an important part of medicine allowing specialist doctors and radiographers to rapidly access a patient’s condition and to help in long-term diagnosis. This enables doctor’s to treat patients before their condition deteriorates. This procedure would not be possible without the use of X-rays, CAT scans, MRI scans, ultrasound and endoscopes, which allow doctors to see inside the body with little or no surgery. Without such equipment doctors would be forced to use invasive techniques, which could cause patients more harm as it increases the risk of infection. A sound or ultrasound wave consists of a mechanical disturbance of a†¦show more content†¦The early work in the 20th century used ultrasound as a therapy tool and it was not until the 1940’s that research began into its use as a diagnostic tool. The use of ultrasound in medicine began during and shortly after the 2nd World War in various centres around the world. (NSC, UK national screening committee) The work of Dr.Karl Theodore Dussik in Austria in 1942 on transmission ultrasound investigation of the brain provided the first published work on medical ultrasonic’s. Although other workers in the USA, Japan and Europe have also been cited as pioneers, the work of Professor Ian Donald and his colleagues in Glasgow, in the mid 1950s, did much to facilitate the development of practical technology and applications. This lead to the wider use of ultrasound in medical practice in the subsequent decades. Rapid technological advances in electronics and piezoelectric materials provided further improvements from energy to greyscale images, and from still images to real-time moving images. The technical advances at this time led to a rapid growth in the applications to which ultrasound could be put. The development of Doppler ultrasound had been progressing alongside the imaging technology, but the fusing of the two technologies in Duplex scanning and the subsequent development of colour Doppler imaging provided even more scope for investigating theShow MoreRelatedThe Physics of Ultrasound Essay888 Words   |  4 PagesWithout the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from 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 haveRead More The Physics of Ultrasounds Essay1717 Words   |  7 PagesThe Physics of Ultrasounds Without the use of physics in the medical field today, diagnosis of problems would be challenging, to say the least. The world of medical imaging in particular has benefited greatly from the use of physics. Ultrasound is sound waves that have a frequency too high for humans to hear. With a shorter wavelength than audible sound, these waves can be directed into a narrow beam that is used in imaging soft tissues (Farr and Allisy-Roberts 183).
