A new phased array ultrasound system generates real-time, two-dimensional tomographic images of the heart at 20 frames per second with 2-4 mm resolution.
Describes the design of a novel phased array ultrasound system capable of real-time, high-resolution cardiac imaging.
A new two-dimensional, real-time, high resolution ultrasound imaging system is described. This system uses a linear array of ultrasound transducers to generate tomographic images of the heart in a circular sector format. Phased array techniques allow rapid steering of the ultrasound beam so that images are produced at the rate of 20 per second, or more, while maintaining a resolution of 2-4 mm throughout the field of view.
vonRamm et al. (1976) studied Cardiac imaging. Phased array ultrasound system was evaluated. A new phased array ultrasound system generates real-time, two-dimensional tomographic images of the heart at 20 frames per second with 2-4 mm resolution.
