Spatio-temporal ultrasound beam modulation to sequentially achieve multiple foci with a single planar monofocal lens

Abstract Ultrasound focusing is a hot topic due to its multiple applications in many fields, including biomedical imaging, thermal ablation of cancerous tissues, and non destructive testing in industrial environments. In such applications, the ability to control the focal distance of the ultrasound...
