Abstract
The benefits of a multi-aperture ultrasound probe can be achieved with add-on devices. Synchronization and correlation of echoes from multiple transducer elements located in different arrays is essential to the successful processing of multiple aperture imaging. The algorithms disclosed here teach methods to successfully process these signals when the transmission source is coming from another ultrasound system and synchronize the add-on system to the other ultrasound system. Two-dimensional images with different noise components can be constructed from the echoes received by individual transducer elements. The disclosed techniques have broad application in medical imaging and are ideally suited to multi-aperture cardiac imaging using two or more intercostal spaces.
