Abstract

Multi-probe ultrasound methods can extend the field of view and improve the spatial resolution of images and have been proven effective in various applications. However, the need for expensive and cumbersome setups, together with the prohibitive real-time implementation, is hampering possible clinical applications. In this work, we present an ultrasound system capable of simultaneously and independently controlling, with a single scanner, up to four probes. Four 64-element Capacitive Micromachined Ultrasonic Transducer (CMUT) arrays were purposely developed and connected to a ULA-OP 256 scanner using four multi-coaxial cables attached to a single connector. High-frame-rate and phased scan modalities were implemented achieving maximum frame rates of 140 Hz and 26 Hz, respectively. As a proof of concept, the system was used to image, at the same time, different regions of interest of a healthy volunteer. The system represents a demonstrator capable of accelerating the research and the implementation of real-time multi-probe applications.
