Reconstruction of the Ultrasonic Image by the Combination of Genetic Programming and Constructive Solid Geometry

We propose a method for improving the highly-degraded images obtained by ultrasonic imaging system. To reconstruct 3-dimensional images from highly-degraded acoustic images, strongly typed genetic programming including constructive solid geometry which is an expression method of 3-dimensional object is used as post processor. In the tree structure of genetic programming, the temporally node is established in order to enable the individual change of type and position information of the primitive. By the experimental results, it is possible to specify type and position of the primitive from the 2-dimensional ultrasonic wave image
