A new method is presented for determining the existence of an embedded object in biological tissue.
We propose a method for modelling tissue containing a simulated tumour. Indications of the existence of a tumour that appear on the surface of the tissue were also determined. FEM provided properties such as the shape, size, depth and location of tumour.
A number of different cases were created and solved by the software and tactile images and stress graphs were extracted. These results clearly showed the existence of the tumour in the tissue. Maximum stresses were used to create tactile maps. Simulation results demonstrated good agreements with other studies.
Three-dimensional analysis leads to a novel method of predicting the characteristics of a tumour and can be directly applied to the incorporation of tactile sensing in artificial palpation, helping surgeons in non-invasive procedures.
提出了一种用于确定生物组织中嵌入物体存在的新方法。
我们提出了一种对包含模拟肿瘤的组织进行建模的方法。还确定了在组织表面出现的肿瘤存在的迹象。有限元法提供了诸如肿瘤的形状、大小、深度和位置等特性。
软件创建并解决了许多不同的案例，并提取了触觉图像和应力图。这些结果清楚地表明了组织中肿瘤的存在。最大应力被用于创建触觉图。模拟结果与其他研究显示出良好的一致性。
三维分析导致了一种预测肿瘤特征的新方法，并且可以直接应用于在人工触诊中纳入触觉传感，帮助外科医生进行非侵入性手术。
