AI Technical Summary

Technical Problem

Existing elastography devices face challenges in accurately compensating for the displacement of ultrasound transducers during tissue characterization, leading to noisy elastograms and increased computational burden, particularly in vibration-controlled harmonic elastography.

Method used

An elastography device with motionless ultrasound transducers and a control system that adjusts temporal offsets upon emission and/or reception based on the transducer's displacement, compensating for time shifts in real-time to align echo signals.

Benefits of technology

This approach reduces computational requirements, minimizes noise, and enables accurate real-time tissue deformation tracking, improving the quality of elastograms without the need for post-processing.
