FAQ

Those interested in the Ultrasound waves images category often ask the following questions:

☑️ How are ultrasound waves different from sound waves?

  • Sound waves are what we hear, ultrasound waves are sound waves that, well, we can not hear. Both need a medium to transmit through. Typically sound waves expand from about 100 Hz to 20 kHz. Ultrasound sound waves are sound waves with frequency higher than 20 kHz.

☑️ How are ultrasound waves different from normal sound waves?

  • As mentioned already, ultrasound waves come with higher frequencies than audible sound waves, but it is also important to understand that these ultrasonic waves have shorter wavelengths. It means the distance between one ultrasonic wave entering your ear and the one following that one is much shorter as compared to normal sound waves.

☑️ Can ultrasound waves travel through a vacuum?

  • Ultrasound travels through various media including gases, liquids and solids, but cannot travel through a vacuum. The speed of sound varies by the medium it travels through.

☑️ How are long bones probed by ultrasound waves?

  • Like tube or pipelines inspected by non destructive ultrasonic testing methods, long bones can be probed by ultrasound waves produced in response to an impact (the ultrasound impulse) transmitted by a source to the bone through the soft tissue. The method has been adapted by our group to reduce artifacts caused by soft tissue [7] (Fig. 3).

☑️ How do ultrasound waves break up kidney stones?

A machine called a lithotripter is used to crush the kidney stone. The procedure is performed by a urologist on an outpatient basis and anesthesia is used. In shock wave lithotripsy, the person lies on a table or, less commonly, in a tub of water above the lithotripter. The lithotripter generates shock waves that pass through the person’s body to break the kidney stone into smaller pieces to pass more readily through the urinary tract.

How does the refraction of an ultrasound wave work?

  • The transmitted ultrasound wave is refracted if the speed of sound is different in the two tissues, with the angle of refraction also referenced to the normal direction. Refraction angle depends on the relative speed differences and the change in the wavelength at the boundary.

How big is the wavelength of an ultrasound wave?

  • This is common with red blood cells (RBC), where the average diameter of an RBC is 7μm, and an ultrasound wavelength may be 300μm (5 MHz). When the sound wave is greater than the structure it comes in contact with, it creates a uniform amplitude in all directions with little or no reflection returning to the transducer.

What determines the initial strength of an ultrasound wave?

  • The initial strength or amplitude of a sound wave is determined by the vibration of the piezoelectric crystal in the transducer. The greater the vibration of the crystal, the larger the amplitude of the ultrasound wave.

How is sound reflected back to the probe in ultrasound?

  • When the sound waves encounter a tissue that absorbs or transmits the sound, a wave is reflected back to the probe. The ultrasound image is white or gray depending on the intensity of the reflection. Unlike x-rays or CAT scans, ultrasound doesn't detect tissue density. Rather, it detects sonotransmission (the passage or reflection of sound).

Which waves are compressional waves?

P waves are also known as compressional waves, because of the pushing and pulling they do. Subjected to a P wave, particles move in the same direction that the the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the 'direction of wave propagation'.

Are light waves electromagnetic waves?

Usually when one says light waves, one is referring to Visible light. Any light wave, and hence visible light, is an electromagnetic wave. As an electromagnetic wave, it is also a transverse wave. The oscillating electric and magnetic fields of an electromagnetic wave in free space are oscillating with a direction perpendicular yo the direction of movement of the wave. The velocity of an electromagnetic wave is the sped of light. This is a sensible things since light is an electromagnetic wave. In a vacuum all electromagnetic waves travel at the same speed. In matter, if the matter allows an electromagnetic wave to propagate, the speed is slower than the speed of light and in optics we say the speed is reduce by the index of refraction, v=c/n. Electromagnetic waves, like all waves, have velocity, wavelength, frequency, amplitude and phase. As with all transverse waves, electromagnetic waves can be polarized, or we say, have a polarization. Electromagnetic waves have electric and magnetic fields that are sinusoidal in space and time. These electromagnetic fields satisfy Maxwell's equations, i.e. the fundamental laws of electromagnetism. There is a quantum version of electromagnetic theory called electrodynamics and that theory is the necessary edification of Maxwell's equations to describe the quantum nature of light. Thus, even when we are discussing light as photons, it is correct to say light is an electromagnetic wave as such is manifested within quantum electrodynamics.

Are sound waves circular waves?

  • When the airplane is flying below Mach 1, the sound waves it generates form a circular shape as a whole. However, when the airplane exceeds Mach 1, then the sound waves it generates form a conical shape as a whole. This is explained by the "falling behind" phenomena, mentioned above in the second paragraph.

Are water waves longitudinal waves?

  • Water waves are surface waves, a mixture of longitudinal and transverse waves. Surface waves in oceanography are deformations of the sea surface. The deformations propagate with the wave speed, while the water molecules remain at the same positions on average. Energy, however, moves towards the shore.

Are lamb waves ultrasonic waves?

"Ultrasonic" is an adjective referring to sound waves at frequencies greater than the typical limit of human hearing. "Lamb waves" are elastic waves propagating in solid plates. Their particle motion lies in the plane that contains the direction of wave propagation and the plate normal (the direction perpendicular to the plate). The characteristic that defines a "Lamb wave" is completely different from the characteristic that defines an "ultrasonic" wave, so the question is a lot like asking "Are human beings American people ?" Some Lamb waves are ultrasonic, and the rest aren't.
