Abstract
An ultrasound imaging system includes an ultrasound probe receiving echo signals from a subject, and a processor converting echo signals received from the probe to echo data corresponding to an ultrasound image. The system also includes a grayscale mapper transforming the echo data received from the processor to a corresponding value of perception data. The grayscale mapper makes this transformation using a DICOM compliant GSDF calibration curve. The perception data is passed to a transform processor, which also receives an ambient light signal from an ambient light sensor. The transform processor converts the perception values to respective digital driving levels based on the ambient light signal and display characteristics of a display device to which the digital driving levels are applied to maintain optimal image display under varying ambient light conditions.
