We describe a novel 3-D ultrasound technology, the quantitative transmission ultrasound system and algorithm to image a pendent breast in a water bath. Quantitative accuracy is verified using phantoms. Morphological accuracy is verified using cadaveric breast and in vivo images, and spatial resolution is estimated. This paper generalizes an earlier 2-D algorithm to a full 3-D inversion algorithm and shows the importance of such a 3-D algorithm for artifact suppression as compared with the 2-D algorithm. The resultant high-resolution ultrasound images, along with quantitative information regarding tissue speed of sound/stiffness, provide a more accurate depiction of the breast anatomy and lesions, contributing to improved breast care.
我们描述了一种新颖的三维超声技术,即定量传输超声系统和算法,用于在水浴中对悬垂乳房进行成像。通过使用体模验证了定量准确性。通过使用尸体乳房和体内图像验证了形态学准确性,并估计了空间分辨率。本文将早期的二维算法推广到全三维反演算法,并表明与二维算法相比,这种三维算法对于抑制伪影的重要性。由此产生的高分辨率超声图像以及关于组织声速/硬度的定量信息,更准确地描绘了乳房的解剖结构和病变,有助于改善乳房护理。
