Dual-strategy approach for high-resolution ultrasound imaging: Resolution-jumping and beamforming
Source abstract
Abstract
The demand for high-resolution ultrasound imaging is increasing, particularly in medical diagnostics, where the number of measurements is often limited due to physical and technical constraints. Ultrasonic tomography, based on linearizing the inverse acoustic scattering problem, enables the detection of small variations in a reference medium. To address these challenges, this study proposes a novel combination of resolution-jumping and beamforming techniques. The resolution-jumping approach progressively refines reconstruction accuracy by leveraging coarse-to-fine information, improving performance under limited measurement conditions. Simultaneously, beamforming employs multiple transmitting elements to generate a narrow beam, effectively reducing noise and enhancing structural detail recovery. Numerical simulations demonstrate that the proposed method significantly improves reconstruction quality while considerably reducing processing time, making it well-suited for real-time, high-resolution ultrasound imaging applications.
