Noise power spectrum and modulation transfer function analysis of breast tomosynthesis imaging

摘要

The recent commercialization of digital breast tomosynthesis systems realizes the clinical applications of this novel three-dimensional imaging technology. The total dosage of breast tomosynthesis for single patient is comparable to that of the traditional mammography. This paper presents our continuous work on image quality analysis for the optimization of a new multi-beam breast tomosynthesis system based on carbon nanotube X-ray emission technology. Several tomosynthesis reconstruction algorithms were implemented to reconstruct the phantom data. Noise power spectrum and modulation transfer function were investigated to evaluate the image quality.
