Abstract
Early detection of cancer can significantly increase the survival chances of patients. Palpation is a traditional method in order to detect cancer; however, in minimally invasive surgery the surgeon is deprived of the sense of touch. We demonstrate how shearing elastography can recover elastic parameters and furthermore can be used to localize stiffness imhomogenities even if hidden underneath the surface. Furthermore, the influence of size and depth of the stiffness imhomogenities on the detection accuracy and localization is investigated.
摘要
癌症的早期检测可显著提高患者的生存几率。触诊是检测癌症的传统方法；然而，在微创手术中，外科医生失去了触觉。我们展示了剪切弹性成像如何恢复弹性参数，并且即使隐藏在表面之下，也可用于定位硬度不均匀性。此外，还研究了硬度不均匀性的大小和深度对检测准确性和定位的影响。
