Bones Characterisation with Ultrasound
Engineering Transactions, 2015 Macroscopic, X-ray methods for bone quality assessment are mainly based on porous bone density measurements. The bone quality is a property that is difficult to define, as it is related to both density and structure of the bone.

Dendriform pulmonary ossification visualised by scanning acoustic microscope [PDF]
Thorax, 2015 A 45-year-old man was referred to our facility because of an abnormal shadow on chest radiography. CT revealed a reticular and nodular shadow (figure 1). Histopathology of a surgical lung biopsy specimen showed dendriform mature bone formation with marrow residing within the alveolar spaces, which was …

Observation of stable crack growth in Al2O3 ceramics using a scanning acoustic microscope
, 2022 We employed ultrasonic techniques in order to gain information on the R-curve behavior of Al2O3 ceramics. A reduction in the sound velocity has been observed at the crack tip of subcritically grown cracks.

Microprobe techniques in SAW measurements
Archives of Acoustics, 2014 Starting from the conventional microprobe techniques, a scanning acoustic tunneling microscope (SATM) and a scanning acoustic force microscope (SAFM) have been developed to detect particle displacements at solid surfaces up to GHz frequencies.

Phase imaging with the scanning acoustic microscope
Electronics Letters, 1976 A new mode of operation for the acoustic microscope is described whereby the phase shift through the object is displayed in the form of an image. Experimental results are presented at an acoustic frequency of 1000 MHz. It is hoped that the `phase-only? images obtained with this technique will complement the conventional amplitude transmission images by
