Abstract
Method and system for computed tomography. Data is collected by irradiating a subject with x-rays. The data is interpolated and then weighted based upon the data collection time. The interpolated and weighted data is then used to reconstruct the image using fan beam reconstruction. The weighting function may by shifted in time. Signals may be obtained from the subject and used to control exposure, reduce the dose and provide automatic volumetric cardiac reconstruction. The method and system can increase the temporal and spatial resolution, and reconstruct images at different timing.
