Abstract
The purpose of this study was to evaluation of the performance characteristic for mammography by using edge device that mammography equipment improves essential in the correct diagnosis for the maintenance. We measured the modulation transfer function (MTF), the noise power spectrum (NPS), and the detective quantum efficiency (DQE) using the 61267 RQA-M2 based on commission standard international electro-technical commission (IEC). As a results, spatial resolution of elenia demensions tomo and lorad selenia mammography were maintained at $10mm^{-1}$ and NPS and DQE including the low nyquist frequency indicated to $6.0mm^{-1}$. Therefore, regulary QA of mammography system should be necessary. This study can be contribute to evaluate QA for performance characteristic of mammography of DDR system.
