Abstract

Digital tomosynthesis is a novel technology to volumetrically reconstruct three-dimensional information with a finite number of low-dose two-dimensional projection images. In digital breast tomosynthesis imaging fields, most current breast tomosynthesis systems utilize a design where a single x-ray tube moves along an arc above objects over a certain angular range. Parallel imaging configurations also exist with new nanotechnology enabled multi-beam x-ray sources. In this paper, a framework is described for comparison and optimization of imaging configurations for digital tomosynthesis. The framework is designed to allow the flexibility of comparison and optimization of various imaging configurations such as parallel imaging, partial iso-centrical imaging, rectangular imaging, etc., with uniform and non-uniform beam distributions where imaging parameters of x-ray tube and detector can be assigned. The proposed framework may assist in the study of digital tomosynthesis and expand tomosynthesis applications to various diagnostic and interventional procedures.
