One woman in 9 will contract breast cancer. Early diagnosis and treatment increases survival rates. A unique feature of our proposed approach is the ultrasound modalities plus x-ray mammography can be obtained in the same scanning machine and the respective images can registered fused and combined. We will demonstrate the following modalities on a purchased NeoVision SONOPSY scanner: 2-d refraction projection, 2-D adsorption projection, and 2-D and 3-D scattering number density images. This machine presently performs ultrasound guided breast biopsy and makes 3-D reflectivity images with about 1.6 mm spatial resolution within a 200 by 300 by 40 voxel volume in one minute. We will demonstrate the improved spatial resolution obtained with phase aberration correction and larger apertures on our 5-ring, 26 segment, annular array in our lb scanner, as preparation for phase 2 SBIR upgrading the NeoVision scanner to 0.57 mm resolution by incorporating F-1.33 annular arrays. We will also simulate a local, 3-D, refractive index, inverse imaging mode for phase 2 SBIR development. These multiple images can be combined in neural nets or probability-of-cancer image. PROPOSED COMMERCIAL APPLICATION: Ultrasound, imaging, synthetic-focus, software, breast, cancer, inverse scattering.

每9名妇女中就有1人会患乳腺癌。 早期诊断和治疗 提高存活率。 我们提出的方法的一个独特之处是 超声模式加上X射线乳房X线摄影可以在 同一台扫描机和各自的图像可以配准融合， 加起来 我们将在购买的 NeoVision SONOPSY扫描仪：二维折射投影，二维吸附 投影以及2-D和3-D散射数密度图像。 这 机器目前进行超声引导乳腺活检，并使三维 在200 × 10 - 6毫米范围内具有约1.6毫米空间分辨率的反射率图像。 300乘40的体素体积。 我们将展示改进的 通过相位像差校正获得的空间分辨率， 我们的5环，26段，环形阵列在我们的LB扫描仪的光圈， 为SBIR第2阶段升级NeoVision扫描仪至0.57 mm做准备 分辨率通过纳入F-1.33环形阵列。 我们还将模拟 用于相位2 SBIR的局部、3-D、折射率、逆成像模式 发展 这些多个图像可以在神经网络中组合， 癌症概率图像。 拟议的商业应用：超声、成像、合成聚焦， 软件，乳腺癌，逆散射。
