Abstract
Generally, image reconstruction by ultrasonics uses reflective data and observation position unidirectional information. This study examines the method to obtain a high quality reconstruction image from projection data of a few directions. To reduce the number of projection data, the model of the object expresses the wavelet function. As the applied wavelet function to be used has high localization property, the quantity required for reconstruction to calculate decreases. Thereby, high quality images are obtainable by computer simulation.
