Method for reducing partial scan artifact in image data of phase-correlated cardio-computed tomography, involves correcting raw data using extracted datasets, and reconstructing image from corrected raw data

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a method and device to reduce artifacts (unwanted distortions) that occur in medical images produced by phase-correlated cardio-computed tomography (CT), especially when using partial scan data. The approach involves simulating full-scan datasets, using those simulations to extract virtual partial scans, and correcting the original raw CT data before reconstructing a clearer image.

Patent Abstract

The method involves calculating a dataset for full rotation scan from raw data of real partial scans or a partial quantity of the partial scans, in an initially simulated manner. Datasets for virtual partial scans with different start angles are extracted from the calculated dataset. The raw data is corrected using the extracted datasets corresponding to initially produced partial scans with the same start angles or a start angle offset about 180 degrees. An image is reconstructed from the corrected raw data. An independent claim is also included for a device for reducing partial scan artifact in image data of phase-correlated computed tomography.
