US 2026/0153483 A1 · A SYSTEM AND METHOD FOR ULTRASOUND IMAGING USING ARBITRARY VIRTUAL ARRAY SOURCES OF APERTURE EXCITATION

Abstract

The present invention discloses a system (100) and method (1200) for ultrasound imaging using arbitrary virtual array sources of aperture excitation. The system (100) comprises at least one user device (102), an imaging device (104), a probe module (106), a sample module (108), a communication network (110) and at least one server (112). The user device (102) is configured to accept input data from the user. The imaging device (104) designed to monitor input data from the user interface and control the functioning of the PAUT probe. The probe module (106) triggers multiple transducer elements based on the input data to generate a wave pattern, where the wave propagates into the sample module (108) for non-destructive testing. The received wave is processed by the imaging device (104) to convert the analogue signal to digital before generating and displaying an ultrasound image of the sample.
