Abstract:
1. A method for carrying out contrast imaging or harmonic imaging in biological tissues without providing the presence of contrast media comprising: acquiring an image array representing an ultrasound or MRI or radiographic image of a certain body or of a certain part of a body; and subjecting the acquired image data array is subjected to a method of image processing comprising: forming an image by a two or three dimensional array of pixels, and having each pixel of the array form a unit or knot of an artificial neural network, wherein an input and an output of the artificial neural network is formed by original values of the pixels corresponding to each unit and by a computed value of each pixel, and wherein a computation of an output value of each one of the knots is carried out as a function of the values at least some of the pixels surrounding the knot, using a neural network comprising: a n-dimensional array of cells (K each cell (K each cell (K the connection between each cell (K each cell being characterized by an internal value defined as the activation value or function (A each cell (K the transfer function determining the output signal (u a n-dimensional database of input data records (P each data record (P the value (U the activation value (A wherein: for each processing step of the said certain number of iterative processing steps, the weights (w the current activation value (A
