METHOD FOR DYNAMIC PRIOR IMAGE CONSTRAINED IMAGE RECONSTRUCTION |
摘要 |
<p>A method for reconstructing a high quality image from undersampled image data is provided. The image reconstruction method is applicable to a number of different imaging modalities. Specifically, the present invention provides an image reconstruction method that incorporates an appropriate prior image into the image reconstruction process. One aspect of the invention is to provide an image reconstruction method that produces a time series of desired images indicative of a higher temporal resolution than is ordinarily achievable with the imaging system, while mitigating undesired image artifacts. This is generally achieved by incorporating a limited amount of additional image data into the data consistency condition imposed during a prior image constrained image reconstruction. For example, cardiac phase images can be produced with high temporal resolution using a state-of-the-art multi-detector CT system with either fast gantry rotation speed or CT imaging system with a slow gantry rotation speed.</p> |
