Physiological Parameter Estimation in PET Dynamic Imaging

摘要

PET (Positron Emission Tomography) dynamic imaging has a great impact on the quantification of physiological parameters in human. However, the physiological parameters, such as glucose metabolic rate and cerebral blood flow, are usually estimated with the measure of a huge amount of PET dynamic imaging data and the troubles of computational cost and memory space. This paper presents a new method for estimating the physiological parameters, which is suitable for the short data of the dynamic imaging in PET studies.
