Color Flash Ultrasound

The color flash artifact is a commonly encountered artifact on color Doppler ultrasound, representing spurious flow signal arising due to tissue/transducer motion. Physics The flash artifact is caused by movement of reflective tissues (e.g. due to respiration), or the transducer, which generates a Doppler shift, and thus a color signal 1.

Doppler spectrum displays no true flow Flash artifact Flash artifact occurs as a result of motion of the patient or the transducer and presents as a sudden flash of color filling the color box and obstructing the grayscale image. It can be useful as "color bruit" that presents as a color mosaic in tissue adjacent to a vessel with turbulent. Taking ultrasound to new heightsThe new ACUSON Sequoia is built with unique and patented BioAcoustic Imaging technologies to virtually eliminate color flash architects and penetrate deeper than conventional ultrasound systems.

D ISCUSSIONS Doppler ultrasound played a very important role in the diagnosis of various pathological conditions related to hemodynamics. Along with other vascular abnormalities, color flow imaging plus grayscale has a key role in the assessment of the anatomic appearance and hemodynamics of transplanted and native kidneys. The following description relates to various embodiments for suppressing flash artifacts during color flow ultrasound imaging.

An example ultrasound system including an ultrasound probe, a display device, and an imaging processing system are shown in FIG. Case Discussion Spurious color noise e.g. that due to flash artifact affects tissues unevenly, with hypo/anechoic structures being much more prone to it.

Also, while an inappropriately high color gain is well-recognized cause of color flash artifacts a too low (!) color. Throughout my career in ultrasound, one of the most frequent and most challenging problems to solve has been related to noise artifacts. Typically, these present as axial bands of constant or flashing color in Color Doppler mode.

The color flash artifact is a commonly encountered artifact on color Doppler ultrasound, representing spurious flow signal arising due to tissue/transducer motion. Physics The flash artifact is caused by movement of reflective tissues (e.g. due to respiration), or the transducer, which generates a Doppler shift, and thus a color signal.

Flash artifacts in ultrasound flow images are suppressed to achieve enhanced flow discrimination. Flash artifacts typically occur as region of elevated signal strength (brightness or equivalent color) within an image. A flash suppression algorithm included the steps of estimating the flash within an image and then suppressing the estimated flash.

The mechanism for flash suppression is spatial.
