## COMPARE DIGITOME AND CONVENTIONAL TOMOSYNTHESIS METHODS

While there are many possible projection geometries to which the Digitome® Volumetric Reconstruction method can be applied, there are three of particular interest: circular, linear, and radial. These geometries are of interest because the fixtures required to produce them are straight forward to design, build, and calibrate. Based upon both theory and experience, the circular projection geometry offers improved results in a wider range of circumstances than either the linear or radial projection geometries.

It is the purpose of this document to describe the three geometries and to present the results from a series of simulated Digitome® exams that will demonstrate the above.

The reader is advised to remember that the results presented in this document are based upon mathematical constructs. All images are computer generated. However, the math has been carefully verified to be a faithful representation of the physical situation except where noted.
