Breast cancer is second only to lung cancer as the leading cause of non-preventable cancer death in women. Digital Breast Tomosynthesis (DBT) is a promising technique to improve early breast cancer detection. In this paper, we present the impulse response and Modulation Transfer Function (MTF) analysis to quantitatively compare Shift-And-Add (SAA) and point-by-point Back Projection (BP) three-dimensional image reconstruction algorithms in DBT. A Filtered Back Projection (FBP) deblurring algorithm based on point-by-point BP was used to demonstrate deblurred tomosynthesis images.
乳腺癌是女性非预防性癌症死亡的主要原因，仅次于肺癌。数字乳腺断层合成（DBT）是一种很有前景的早期乳腺癌检测技术。在本文中，我们进行了脉冲响应和调制传递函数（MTF）分析，以定量比较DBT中移位相加（SAA）和逐点反投影（BP）三维图像重建算法。基于逐点BP的滤波反投影（FBP）去模糊算法被用于展示去模糊后的断层合成图像。
