During the past year, we have been working on creating a suitable phantom for three-dimensional (3D) ultrasound image reconstruction of the oropharynx. We had a six-surface plastic structure made with a 1-mm steel ball implanted at various distances from the surface. Then 14 calibration measures were obtained from each surface using our transducer with a specially mounted 3D spatial tracker. We were able to obtain data that closely matched the acquisition formulae we used as a model. We are continuing to attempt to produce 3D images from our test data file, but there appears to be an error in the program. In order to progress in our work, we are examining other 3D construction algorithms and exploring use of commercial systems for 3D ultrasound imaging. Once completed, this project will have widespread application for tumor tracking and swal-lowing function. - 3D ultrasound,ultrasound tissue characterization

在过去的一年中，我们一直致力于创造一个合适的三维（3D）超声图像重建的口咽体模。我们有一个六面的塑料结构，在离表面不同距离处植入一个1毫米的钢球。然后，使用我们的传感器和专门安装的3D空间跟踪器从每个表面获得14个校准测量值。我们能够获得与我们用作模型的采集公式非常匹配的数据。我们继续尝试从我们的测试数据文件中生成3D图像，但程序中似乎存在错误。为了在我们的工作中取得进展，我们正在研究其他3D构建算法，并探索使用商业系统进行3D超声成像。一旦完成，该项目将广泛应用于肿瘤跟踪和吞咽功能。- 3D超声，超声组织定征
