1. A method for reconstructing a borehole image, the method comprising: (a) determining a spatial sensitivity function for a borehole imaging tool; (b) using the borehole imaging tool to obtain a borehole image of a subterranean formation; and (c) computing a reconstructed image from the borehole image obtained in (b) and the spatial sensitivity function determined in (a) according to the following mathematical equation: 
 A·X=B wherein A·X represents a linear convolution of A and X, A represents a two-dimensional spatial sensitivity function in two-dimensional matrix form as determined in (a), B represents the borehole image obtained in (b), and X represents the reconstructed image.
