Small lesion detection with resolution enhancement compression: a method of coded excitation/pulse compression
A novel coded excitation method, resolution enhancement compression (REC), increases the axial resolution and the echo signal-to-noise ratio (eSNR) for an ultrasonic imaging system. The REC technique was examined for its ability to improve lesion detectability. In addition to lesion detectability, …
