✦ Synopsis
Contemporary real-time ultrasound images are constructed of graduated shades of gray. The practical range of echo contrast than can be depicted is therefore limited. The use of color as well as intensity would potentially increase the amount of information available and possibly augment tissue texture contrast. Previous efforts to color encode ultrasound images have not been of adequate visual resolution, and have not produced simultaneous or real-time results. Described and illustrated here is a microcomputer-based system that successfully produces high-resolution simultaneous real-time pseudocolor transformation of real-time ultrasound images. The system accepts the composite video output in any ultrasound machine, and the specific color scheme may be chosen to suit the operator. It is proposed that such color enhancement improves visual clarity of fine fetal anatomy by highlighting tissue-tissue contrast and tissue-fluid interfaces.
