Abstract
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.
