Cite This Study
Ryan et al. (1987) conducted a review in Cardiac imaging. Annular array imaging vs. Phased-array and mechanical transducer technology was evaluated on Image quality. Annular array imaging improves ultrasonic cardiac image quality through dual-plane electronic focusing, providing deeper penetration, improved lateral resolution, and a thinner tomographic slice.
