An ultrasound imaging system has an improved dynamic range control which enables a user to reduce image haze with substantially no effect on bright tissue in the image and without increasing speckle variance. A dynamic range processor processes an input image to produce an approximation image which is a spatially low pass filtered version of the input image. The dynamic range of the approximation image is compressed, and image detail, unaffected by the compression, is added back to produce a dynamically compressed image for display.

Ultrasound imaging system with improved dynamic range control

An ultrasound imaging system according to the present disclosure may include an ultrasound probe, a display unit, and a processor configured to receive source image data having a first dynamic range, wherein the source image data comprises log compressed echo intensity values based on the ultrasound echoes detected by the ultrasound probe, generate a histogram of at least a portion of source image data, generate a cumulative density function for the histogram, receive an indication of at least two points on the cumulative density function (CDF), and cause the display unit to display an ultrasound image representative of the source image data displayed in accordance with the second dynamic range.
