中文摘要: 天元数学交流项目将以光声成像和超声成像的联合反演作为主题,研究相关的反问题的理论和快速算法。将邀请国内外的从事光声成像和超声成像的顶尖学者做学术报告,聚集国内从事逆散射问题研究的学者对该问题的实际背景和目前遇到的难点进行比较深入的研讨。争取在一些关键的技术和快速算法上取得一些共识。我们的研究方案是:1. 利用超声成像技术,得到介质的信息。2. 将从超声成像中得到的介质信息用到光声成像的源项反演中。由于这种联合反演可以将两种反演方法的优点进行互补,可望得到更加清晰和稳定的成像。

英文摘要: This Tian Yuan Mathematical Exchange Program’s theme is the combined inversion of photoelectric imaging and ultrasound imaging. We will manly study the relevant inverse theory and fast algorithm. Some top international researchers in the fields of photoacoustic imaging and ultrasound imaging will be invited to give the talks in the workshop. We will also invite the talent researchers, who are working on the inverse scattering and fast algorithms, attend the workshop. It is hoped that the participants will understand and discuss the actual background of the problem and the current difficulties encountered. Our research plan is as follows: 1. By ultrasound imaging technology, the rough information for the media can be obtained. 2. We can use the rough media information obtained from ultrasound imaging in the source term inversion of photoacoustic imaging. Because this combined inversion can complement the advantages of the two inversion methods, it is expected that more clear and stable imaging will be achieved.
