In this paper we present a technique for fully automatic, real-time 3D SPECT (Single Photon Emitting Computed Tomography) and 2D ultrasound image registration. We use this technique in the context of kidney lesion diagnosis. Our registration algorithm allows a physician to perform an ultrasound exam after a SPECT image has been acquired and see in real time the registration of both modalities. An automatic segmentation algorithm has been implemented in order to display in 3D the positions of the acquired US images with respect to the organs.
在本文中，我们提出了一种用于全自动、实时三维单光子发射计算机断层扫描（SPECT）和二维超声图像配准的技术。我们将此技术应用于肾脏病变诊断。我们的配准算法允许医生在获取SPECT图像后进行超声检查，并实时查看两种模态的配准情况。为了以三维方式显示采集到的超声图像相对于器官的位置，我们实现了一种自动分割算法。
