Abstract
A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate physical apertures of ultrasound arrays. The probe can include separate backing plates configured to secure the ultrasound arrays in predetermined positions and orientations relative to one another. Some embodiments of the probe include flex circuit connected to the ultrasound arrays. In additional embodiments, a flex/PC board comprising flex connectors and an array of terminals is connected to the ultrasound arrays. Algorithms can solve for variations in tissue speed of sound, thus allowing the probe apparatus to be used virtually anywhere in or on the body.
