摘要
本论文阐述的是断层重建技术在核医学领域的应用。通过投影滤波技术把病灶在二维空间的图像,扩展到三维空间,得到病人病灶纵深的“信息”,使临床医生更好、更快的定位病灶和了解病情。
This paper discussed the theories of emission computed tomography reconstruction in the area of nuclear medicine, the image of focus expand from two dimension space to three dimension space, thereby we can get the deep information of focus and the clinicians can know the state of an illness faster.
