Abstract: An ultrasonic includes: a piezoelectric layer; an absorbing layer disposed at a lower portion of the piezoelectric layer, configured to absorb an acoustic signal; and a connection part disposed between the piezoelectric layer and the absorbing layer. The connection part may deform at least partially so that a plurality of acoustic signals radiated from the piezoelectric layer due to the connection part have different magnitudes. In the case of the ultrasonic probe, since the magnitude of the acoustic energy radiated from the center of the ultrasonic probe is larger than the magnitude of the acoustic energy radiated from the side of the ultrasonic probe, the directivity of the ultrasonic signal is improved and a side lobe is decreased. In addition, an apodization effect capable of suppressing overlapping between adjacent phases can be obtained by using a difference in the magnitude of the acoustic energy to be radiated.

Abstract: A computer implemented method for generating synthetic training data to train a convolutional neural network is described. The method consists of steps including receiving a source image depicting an object for identification. The type and shape of the depicted object is determined. The source image is overlayed with a N×M grid of vertices, the grid including horizontal and vertical edges and being fit to the shape of the depicted object. For each vertex in the grid, perturbations are added to the (x,y) coordinates of the vertex and the pixel values in a range between the original and final (x,y) coordinates are interpolated, resulting in the generation of an item of synthetic training data. The method is repeated to generate multiple items of synthetic training data which are then used to train a neural network to identify the object in an image.
