Název v původním jazyce

Imaging of human tooth using ultrasound based chirp-coded nonlinear time reversal acoustics

Popis výsledku v původním jazyce

The complexity of the tooth internal structure (enamel?dentine interface, cracks between internal tubules) is analyzed by adapting the nonlinear elastic wave spectroscopy (NEWS) with the objective of the tomography of damage. Optimization of excitationsis proposed using time reversal (TR) invariance, reciprocity, correlation properties, etc. The TR-NEWS approach is implemented on a third molar human tooth. A 10 MHz bandwidth ultrasonic instrumentation is used, including laser vibrometer and a 20 MHz contact piezoelectric transducer. Nonlinear signature coming from the symmetry properties is experimentally observed in the tooth using bi-modal TR-NEWS imaging after and before focusing induced by the time-compression process. The TR-NEWS polar B-scan ofthe tooth is described and suggested as a potential application for modern echodentography.
