Application of a knowledge-based system to the interpretation of ultrasound images

Some of the problems of computer interpretation of medical ultrasound images and the use of an expert system to control the image processing and model matching are discussed. An expert system shell developed for this task is briefly discussed, and preliminary application to an ultrasound scan is detailed. The anatomical and geometric structures involved are modeled as a network of frames. This modeling and the model-matching control strategy used are discussed with reference to example images and the feedback aspects of the control mechanism
