摘要
介绍了一种基于崭新学术思想的医用成像技术——微波激励热声 CT,这一技术架起了超声 CT和微波 CT功能和技术上优热互补的桥梁。在介绍它的成像原理的基础上 ,进而介绍了刚刚起步进行研究的两个实验装置和相应的成像实验 。
A brand new imaging technology,which is based on microwave induced thermoacoustic effect and is called microwave induced thermoacoustic tomography,is introduced in this paper.The technology may bridge the gap and combine the advantages of the two imaging modalities purely altrasound tomography and purely microwave tomography.The principle of microwave induced thermoacoustic tomography is describled at first,then two experimental setups and calculations of thermoacoustic signal are introduced.
