The system as recited in claim 1, wherein said computer is further programmed to perform the following steps: (d) in order of increasing pixel intensity values, testing each in a succession of bins to determine whether the bin being tested has a count equal to or in excess of a predetermined threshold; (e) if a bin has a count equal to or in excess of a predetermined threshold, identifying a brightness enhancement pixel intensity value having a count equal to said predetermined threshold; and (f) changing the value of each pixel intensity value in at least said second and third ranges by said brightness enhancement pixel intensity value. 6. The system as recited in claim 5, wherein said computer is further programmed to determine a skewness state of said histogram, a sign of a change made in said step (f) being dependent on said skewness state. 7. An imaging system comprising a data acquisition system for acquiring acoustic data, an image processor for converting acoustic data into a first set of pixel intensity values for an image, a display monitor for displaying the image, and a computer programmed to perform the following steps: (a) enhancing a contrast of the image to be displayed by processing said first set of pixel intensity values in accordance with a first algorithm, a result being a second set of pixel intensity values; (b) enhancing a brightness of the image to be displayed by processing said second set of pixel intensity values in accordance with a second algorithm different than said first algorithm, a result being a third set of pixel intensity values; (c) further enhancing the contrast of the image to be displayed by applying a mapping to said third set of pixel intensity values, a result being a fourth set of pixel intensity values, wherein said mapping is derived by processing a subset of said third set of pixel intensity values in accordance with a third algorithm different than said first and second algorithms, wherein said subset corresponds to a region of interest in the image to be displayed; and (d) displaying the image as a function of said fourth set of pixel intensity values on said display monitor, wherein said step (a) comprises the following steps: computing histogram data from said first set of pixel intensity values, said histogram data comprising counts representing a number of pixels having pixel intensity values belonging to a respective bin, said bins being defined to encompass non-overlapping subsets of pixel intensity values, each subset comprising either a different pixel intensity value or a different range of pixel intensity values; and decreasing the pixel intensity values in bins having pixel intensity values in a first range of lowest pixel intensity values, said first range including a predetermined fraction of a total count of pixel intensity values, said decrease in pixel intensity values in said first range being implemented by multiplying each pixel intensity value in said first range by a multiplication factor, said multiplication factor being less than unity and greater than zero. 8. The system as recited in claim 7, wherein step (a) comprises the step of generating a histogram for said first set of pixel intensity values. 9. The system as recited in claim 8, wherein step (b) comprises the step of determining a skewness state of said histogram. 10. The system as recited in claim 7, wherein step (c) comprises the step of generating a histogram for said third set of pixel intensity values. 11. The system as recited in claim 7, wherein said predetermined fraction is equal to about 1/3. 12. The system as recited in claim 7, wherein said step (a) further comprises the step of decreasing the pixel intensity values in bins having pixel intensity values in a second range of pixel intensity values excluding at least a third range of highest pixel intensity values, wherein said first through third ranges do n
