A numerical simulation study of three linear array arrangements for vlbro-acoustography

Research output: Contribution to journalConference articlepeer-review


In this work, we study the beamforming of three linear array transducers for vibro-acoustography systems: separated, interlaced, and randomly interlaced. Each transducer is composed of two linear arrays. The goal of this research is to model and design a system with a linear array probe for in vivo applications. The system pointspread function is given in terms of the dynamic ultrasound radiation force produced by the interference of the ultrasound beams generated by each array. Simulations using a lateral aperture of 48 mm and array parameters similar to conventional ultrasound systems present the resolution cells smaller than 1.4 × 2.8 × 6.1 mm in azimuth, elevation, and range. The interlaced transducers exhibit transverse resolution acceptable for medical imaging applications.
