An Algorithm for Rendering Force Fields at Many and Close Control Points Using Acoustic Holography for Ultrasound Therapy
Ultrasound therapy is advantageous because it is a noninvasive treatment for the body. Low-intensity pulsed ultrasound can aid fracture healing. We focus on phased array transducers (PATs) to render force fields and realize the improvement in medical equipment to enhance this therapy. This can both render an arbitrary acoustic field and quickly change it by controlling the output and phase of each transducer. There are some algorithms for controlling PATs; however, the effectiveness of these algorithms is limited at sparse control points. We propose a novel algorithm to control PATs at many and close control points in this research. We compare the proposed algorithm with previous ones and assess the avoidance of negative effects outside the target area. The findings show that the proposed algorithm achieves both excellent reconstruction performance and low computational cost, and it can render an acoustic field sufficient to prevent negative effects on the body.
