Optimized Coherence Masking Improves Ultrasound Imaging of Kidney Cysts
Journal of Ultrasound in Medicine, EarlyView.Objectives Renal cystic lesions are exceedingly common and typically benign, though accurate diagnostic techniques are required to recognize the subset of malignant lesions that require timely intervention. Ultrasound (US) is the preferred first line test for renal cyst evaluation because it is safe, widely accessible, and low cost. US imaging, however,

In Situ Acoustic Monitoring of Focused Femtosecond Pulse Duration in Air
Laser &Photonics Reviews, EarlyView.Air‐breakdown acoustics at the laser focus is used to determine femtosecond pulse duration with a simple USB microphone. By chirp‐tuning and compressing 1030 nm pulses from 241 to 50 fs, the acoustic amplitude scales inversely proportional to the square root of the pulse duration, enabling in situ readout over 50 fs–5 ps—crucial for precise pulse ...
