Method and system for performing a low-dose CT imaging

摘要

The method includes the step of generating a high-resolution image data based on an incomplete low resolution projection data and high-resolution projection data that is undersampled. Incomplete low resolution projection data and high-resolution projection data that is undersampled is collected during a collection interval of different same scan. System between the low resolution and high resolution in a coordinated manner and composed-ray source, a modulation of the flux to modulate alternately release radiant flux fleeting flow and low Taka-ryu bunch during the integration period of different scan Re high-resolution image data based on projection data corresponding to an incomplete low resolution projection data and configured detector array, a high-resolution projection data that is undersampled to alternately switch to the detector pixel multiplexing and a composed reconstructor to be configured.
