The Effect of Dynamic Beam Deflection and Focus Shift on the Acoustic Field Distribution Inside the Ultrasonic Ring Array

This paper presents the results of acoustic field distribution simulations for 1024-element ultrasonic ring array intended diagnosis female breast tissue with use ultrasound tomography. For purpose analysing data, all fields created by each elementary transducer were combined. The natural position focus inside was changed altering activation time individual transducers in sectors consisting 32, 64, and 128 transducers. Manipulating the position will allow to concentrate beam a chosen location interior space array. goal this research is receive best possible quality images cross-sections breast. study also analysed influence on inclination beam. enable choose an optimal number activated
