The invention concerns an imaging method for observing the propagation of a low-frequency shearing pulse wave simultaneously in multiple points of a diffusing viscoelastic medium (1). The method consists in transmitting at 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.
