Abstract

A method color Doppler imaging in accordance with some examples of the present disclosure includes transmitting with a probe of an ultrasound imaging system, ultrasound pulses towards a region of interest in a subject, receiving with the probe echoes responsive to the pulses, generating B-mode image data and Doppler signals based on the ultrasound echoes, filtering the Doppler signals, wherein thefiltering includes rejecting lower intensity signals which have amplitudes below a threshold amplitude and passing higher intensity signals which have amplitudes above the threshold amplitude, generating color data based on the higher intensity signals, overlaying the color data with the B-mode image data to produce a color Doppler image, and displaying the color Doppler image in a kidney stone detection interface.

Description

technical field [0001] The present application relates to ultrasound imaging, and in particular to the use of color Doppler imaging operating in a specific mode configured for kidney stone detection. Background technique [0002] Kidney stone disease afflicts approximately 10 percent of Americans and seriously affects patients' quality of life. In general, the preferred imaging modality for detecting kidney stones is computed tomography (CT). Although the use of ultrasound, particularly the use of flicker artifact (TA) in color Doppler ultrasound imaging, has been proposed, this method has had limited application in successfully detecting kidney stones. Flicker artifact (TA) appears as a dynamically changing ultrasound color display for kidney stones. Studies have shown that the main contributors to TA are microvesicles that can be found on the surface of kidney stones. Although TA has been used in the past to aid in kidney stone detection, the diagnostic accuracy of kidn...
