The Physics behind Sonography Technology
Megan Rabideau
November 25, 2017 Sonography is a type of imaging that uses high frequency Ultrasound Waves to produce images of the body. The Ultrasound Technology can use different frequencies depending on what is needed to record. The higher the frequency, the smaller the length of the wave will be. Higher frequency sound waves are used to produce images of the body that are closer to the outside of the body. Lower frequency sound waves are used for structures of the body that are deeper in caparison. They are still in the high range for frequency but it is less than what is used with areas of the body that are towards the outside. The frequency measurement used in Sonography is usually between …show more content…

A refraction, is a bend in the Ultrasoundwaves. Now, when the sound wave refracts towards the transducer, it does not go in a straight line towards the detector. The reflected angle will be the same as the angle of the incident wave. How the incident wave refracts all relies on what angle it was at when the wave hit the structure. Since the wave won't go in a straight line towards the Transducer, the image will not be clear and could possibly be changed in the process. (Aldrich, 2007) This will be a diffuse reflection. The sound wave will bend and depending on how the angle is when it hits the surface, will determine what the angle is of the sound wave. The Ultrasound systems are programmed that sound goes in a straight line. Since the refraction is not in a straight line, the image will not look as it is supposed to. The image on the Sonogram will not be of high-resolution and the image could have been changed by the Ultrasound system because of this incident. So if a refraction occurs, you will not have an accurate …show more content…

It will take the Ultrasound waves and change them into an electrical signal which we can see during the Ultrasound or on the sonogram. When the soundwave reflects off of the structure in the body, the wave will reflect towards the Transducer. When the Ultrasound wave reflects off of the object, the altitude changes. The greater change in altitude, the clearer the sonogram will be. When the wave hits the structure, and the altitude changes, the wave will reflect back. Which produces the image we see on the Ultrasound. This high-frequency test is used frequently to see the condition of a fetus in the mother's womb. The child will not be harmed since the Ultrasound just uses high-frequency Ultrasound Waves to produce the image. Which will produce a clear Sonogram to evaluate what is happening in the

Introduction The purpose of this lab was for students to understand and explore their knowledge of standing, transverse, and longitudinal waves using a Slinky spring. It also served to investigate and verify the connection between waves and their specific properties such as: amplitude, wavelength, frequency, and period. Amplitude is directly related to the amount of energy transmitted by a wave. For a transverse wave, the amplitude is the maximum displacement above or below its position of equilibrium.

(The umbilical cord insertion can be not located lateral or central onto the placental plate.) Also, a diagnosis of placenta accreta can occur, meaning the myometrical invasion by villi tissue, caused by the partial or complete absence of deciduas basalis or of placenta previa, which is an abnormal position of the placenta. (Placenta previa can be categorized as complete, incomplete, partial and low-lying placenta) Another diagnosis are the vascular chorioangiomas, which are associated with increased polyhydramnio and fetal growth retardation and associated with the latter, the vascular placental lesions, such as infarcts and large thrombosis. What is more, complete or partial hydatidiform mole, both associated with trophoblastic tumours and the absence of one umbilical artery causing many fetal anatomical defects can be diagnosed with the use of

The impedance is the change between two mediums. Vibrations have to defeat this impedance going trough the outer and middle ear, known as the sound conductive mechanism. “Vibration is poorly transmitted at the interface between two media which differ greatly in characteristic impedance (product of density of the medium and speed of sound within it, pc), as for example air and water.” The inner ear works perfectly well but sound connect go through the other parts to be transmitted to the brain. This type of hearing loss concerns all the frequencies, but much more on the lower

Physics Of Ultrasound Essay

The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.

The purpose of this lab was to observe the phenomenon of resonance in an open ended cylindrical tube and use resonance to determine the velocity of sound in air at regular temperatures. A hypothesis for this lab was that if the frequency of the tuning fork increased, then the length of the tube to achieve resonance will increase because of the high amplitude of the vibration. The resonance of the open-closed tube was found through these steps. First, the tube was filled with water with an inner tube inside the outer tube. The water temperature was measured.

For the past 70 years, ultrasounds have been continually evolving with both diagnosis and treatment. An ultrasound is a type of diagnostic imaging technology. This technology uses sound waves to develop images based on the internal structures of the body. When the sound waves are being projected from a transmitter attached to the ultrasound and hits tissue, the sound waves reflect and create echoes which create a picture on the screen, the shorter the wavelength, the finer the detail of the picture. This is used to help physicains discover the reasoning of a patient’s pain, swelling and infection.

Reflection And Refraction In Media

1923 Words | 8 Pages

Refraction: Refraction occurs when light enters a more or less optically dense medium, which therefore has a different refractive index (measure of the velocity light can travel at in the medium compared to in a vacuum in which it can travel at 2.9 x 108ms-1). This causes the light’s speed to increase or decrease, which results in the rays bending towards or away from the normal, so the position of the image formed is dependent on the refractive indices of the two media. For refraction to occur, the light rays have to hit the boundary between media at an angle to the normal (which is 90 degrees to the boundary), otherwise no change in direction will occur, only a change in velocity. Therefore, if the light rays hit the boundary between the different media at a perpendicular (90 degree) angle, they will continue to go straight. This occurs because the angle at which the rays hit the boundary (called the angle of incidence) determines the angle at which the rays will refract (called the angle of refraction).
