Methods, simulations, and apparatus are provided that may be utilized for medical treatments which are especially suitable for treatment of benign prostatic hyperplasia. The method includes the steps of: providing an input digital image of the chest radiograph; preprocessing the input digital radiographic image; classifying the view of the input digital radiographic image; and determining the orientation of the input digital radiographic image. In supporting the stack of panels as the bottom panel is freed, the bottom panel can be slid out from under a stack without damaging the facing of the panel. In some instances, the method also includes forming a configuration layer for routing among a subset of the vias to provide at least the amount of overlap area for each via in the subset, and for forming the via caps for unrouted vias that are not part of the subset.
