Abstract
The invention concerns an image method for observing the propagation of low-frequency shearing pulse wave simultaneously in multiple points of a diffusing viscoelastic medium. The method consists in transmitting at a very high rate ultrasonic compression waves enabling to obtain a succession of images of the medium; then in delayed processing of the resulting images by intercorrelation to determine in each point of each image the movements of the medium while the shearing wave is being propagated.
