| 摘 要： | 提出一种光谱体层析图像重建新算法.通过计算机数值模拟, 考察了该算法对非对称单峰发射系数场分布的重建效果,并与传统的三维重建算法进行比对.结果表明，该算法具有收敛快，重建准确度高的特点，仅用两个方向的投影数据就能高准确度地重建单峰三维发射系数场分布.作为一个应用实例, 结合谱线相对强度测量方法重建了自由电弧等离子体的三维温度场分布.

| Abstract: | A volume reconstruction approach of emission spectra was proposed,whose three dimensional reconstruction performance was studied by numerical simulation.Results show that this new algorithm has faster convergence velocity and higher precision compared with common used approaches and a three dimensional single-peak phantom was reconstructed precisely only with two projection angels.An arc plasma temperature distribution was also obtained in our application experiment of this approach. |
