Scanning acoustic microscopy for material evaluation [PDF]
Applied Microscopy, 2020 Scanning acoustic microscopy (SAM) or Acoustic Micro Imaging (AMI) is a powerful, non-destructive technique that can detect hidden defects in elastic and biological samples as well as non-transparent hard materials. By monitoring the internal features of

Stiffness reduction and collagenase resistance of aging lungs measured using scanning acoustic microscopy [PDF]
PLoS ONE, 2022 Lung tissue stiffness is altered with aging. Quantitatively evaluating lung function is difficult using a light microscope (LM) alone. Scanning acoustic microscope (SAM) calculates the speed-of-sound (SOS) using sections to obtain histological images by ...
