Paper Abstract

Coherent medical ultrasound images include high contrast speckle artifact. Low contrast, slowly varying image components, such as subtle tissue reflectivity changes due to a diffuse disease state, are difficult to perceive under such conditions. Physicians do not trust smoothed images followed by contrast stretching because of loss of other detail which is considered important. However, the color perception of human observers is ideally suited to the lower spatial frequencies. This paper discusses a technique in which color tinting is used to enhance the low spatial frequency information content of a medical ultrasound image. The resulting images present detail as reduced contrast luminance and slowly varying local average values as hue or chroma.
