我们之前开发了一种方法，将微型伽玛相机和光学相机结合起来，合成两种图像，帮助外科医生在癌症切除手术中轻松识别胃表面的前哨淋巴结。由于该方法假定物体表面为平面，因此其应用范围有限。在本文中，我们扩展了这种方法，以便从立体光学相机中估计物体的三维形状。构建了一个由一台微型伽马相机和两台光学相机组成的原型系统，并进行了刚性机械制造体的初步实验。通过与先前方法的结果比较，我们证实了使用三维形状的有效性。
We have previously developed a method that combines a mini gamma camera with an optical camera to synthesize the two kinds of images and help surgeons to easily identify sentinel lymph nodes on the gastric surface in cancer resection surgery. Since we assumed in this method that the object surface is flat, its application was limited. In this article, we extend this method so as to estimate the three-dimensional shape of the object from stereo optical cameras. A prototype system with a mini gamma camera and two optical cameras was constructed and a preliminary experiment with a rigid machine-made phantom was performed. From comparison with results obtained by the previous method, we confirmed the effectiveness of using the three-dimensional shape.
