Acoustic artifacts
108
P6992-4, EN, 16/12/6
Acoustic saturation occurs when received signals reach a system’s high-amplitude limit At that point the
system becomes unable to distinguish or display signal intensities At the point of saturation, increased
input will not increase output
Aliasing occurs when the detected Doppler frequency exceeds the Nyquist limit It is characterized on the
spectral display by the Doppler peaks going off the display, top or bottom, and then continuing on the other
side of the baseline On the Color display an immediate change in color from one Nyquist limit to the other
is seen
Comet tail is a form of reverberation artifact produced when two or more strong reflectors are close
together and have a high propagation speed In this case, sound does not travel directly to a reflector and
back to the transducer and a strong linear echo appears at the reflector and extends deeper than the
reflector
Enhancement is an increased relative amplitude of echoes caused by an intervening structure of low
attenuation Focal enhancement, also known as focal banding, is the increased intensity in the focal region
that appears as a brightening of the echoes on the display
Mirror imaging artifact is most commonly seen around the diaphragm this artifact results from sound
reflecting off another reflector and back
Mirroring is the appearance of artifacts on a spectral display when there is improper separation of forward
and reverse signal processing channels Consequently, strong signals from one channel mirror into the
other
Multi-path positioning and refraction artifacts describe the situation in which the paths to and from a
reflector are different The longer the sound takes traveling to or from a reflector, the greater the axial
error in reflector positioning (increased range) Refraction and multi-path positioning errors are normally
relatively small and contribute to general degradation of the image rather than to gross errors in object
location
Propagation speed errors occur when the assumed value for propagation speed by the ultrasound system
is incorrect If the actual speed is greater than that assumed, the calculated distance to a reflector is too
small, and the reflector will be displayed too far from the transducer Speed error can cause a structure to
be displayed with incorrect size and shape
Range ambiguity can occur when reflections are received after the next pulse is transmitted In ultrasound
imaging, it is assumed that for each pulse produced, all reflections are received before the next pulse is sent
out The ultrasound system calculates the distance to a reflect or from the echo arrival time assuming that
all echoes were generated by the last emitted pulse The maximum depth to be imaged unambiguously by
the system determines its maximum pulse repetition frequency
Reverberation is the continuing reception of a particular signal because of reverberation rather than
reflection from a particular acoustic interface This phenomenon is analogous to the effect created by
mirrors positioned on opposite walls when an object, a head for instance, is placed between the mirrors
The image of the head is reflected back and forth infinitely between the two mirrors, creating the optical
illusion of multiple heads Reverberations are easily identifiable, because they are equally spaced on the
display
Scattering is the diffuse, low-amplitude sound waves that occur when acoustic energy reflects off tissue
interfaces smaller than a wavelength In diagnostic ultrasound, Doppler signals come primarily from
acoustic energy back-scattered from red blood cells
Shadowing is the reduction in echo amplitude from reflectors that lie behind a strongly reflecting or
attenuating structure This phenomenon occurs when scanning a lesion or structure with an attenuation
rate higher than that of the surrounding tissue The lesion causes a decrease in beam intensity, which
results in decreased echo signals from the structures beyond the lesion Consequently, a dark cloud behind
the lesion image forms on the display This cloud, or shadow, is useful as a diagnostic clue
Side lobes (from single-element transducers) and grating lobes (from array transducers) cause objects that
are not directly in front of the transducer to be displayed incorrectly in lateral position
