Systems and methods for reconstruction of emission activity image

Systems and methods for reconstruction of emission activity image

Aspects of the invention relate to generating an emission activity image as well as an emission attenuation map by using an iterative updating based on both the raw emission projection data and the raw radiography projection data, and an optimization function. The outputs include an optimized emissi...

description Aspects of the invention relate to generating an emission activity image as well as an emission attenuation map by using an iterative updating based on both the raw emission projection data and the raw radiography projection data, and an optimization function. The outputs include an optimized emission activity image, and at least one of an optimized emission attenuation map or an optimized radiography image. In some aspects, an attenuated corrected emission activity image is obtained by using the optimized emission activity image, and the optimized emission attenuation map. 本发明的方面涉及使用迭代更新基于原始发射投射数据和原始射线照相投射数据两者以及优化函数生成发射活动图像以及发射衰减图。输出包括优化发射活动图像和优化发射衰减图或优化射线照相图像中的至少个。在些方面中，使用所述优化发射活动图像和所述优化发射衰减图获得衰减被校正的发射活动图像。
