Diseño de un escáner ultrasónico para la construcción de un diagrama de capas del cerebro de un porcino joven con base en el procesamiento de señales sísmicas

Abstract

The pressure variations produced by a piezoelectric transducer are mechanical waves similar to those generated by a seismic shot with a controlled frequency and bandwidth. This shot is used to disturb the medium (the first meters of the subsoil), generating S, P, Love and Rayleigh waves, in different amplitude and spectral component. The changes that these waves suffer when moving in the middle, with respect to the source, allow to parameterize some physical properties of the disturbed medium. Using an ultrasound transducer as a trigger source and hardware specially designed for this purpose, the in vitro brain of a young porcine is subjected to a longitudinal wave, in order to obtain a layer diagram similar to those obtained in the explorations. Seismic reflection, as the first stage of validation of the hardware designed for the construction of a scanner cerebral viscoelasticity.
