超声断层扫描是检测乳腺癌的一种有吸引力的成像方法。乳房的复杂解剖结构及其不同的空间尺度和材料属性对比使得精确重建非常具有挑战性。本文提出了一种混合的方法,即飞行旅行和衍射层析成像相结合,以实现高分辨率和高精度的声速重建。用几个数值模型对该方法进行了验证。
Ultrasound tomography is an attractive imaging method for the detection of breast cancer. The complex anatomy of the breast with its different spatial scales and material property contrasts make accurate reconstructions very challenging. This paper proposes a hybrid approach whereby Travel-of-Flight and Diffraction Tomography are combined together to achieve high-resolution and high-accuracy sound-speed reconstructions. The method is validated with several numerical phantoms.
