1. A method for forming an image of an object, the method comprising:

  • (a) performing a cone-beam scan of the object in a scanning plane by using a cone-beam emitter and a detector to perform a half-circle scanning geometry so as to obtain projection data for a plurality of rows;

    (b) weighting the projection data with a weighting factor to produce weighted projection data, wherein the weighting factor decreases as the rows become farther from the scanning plane, wherein the weighting factor is a function of a weighting angle which is a function of the row and a scan angle, wherein the weighting angle is
