In one embodiment, a method for computed tomography imaging comprises generating an original image comprising multiple subvolumes, segmenting the original image into different structures for each subvolume, selectively applying a mask-based correction through each area of subvolume that includes continuous structures to generate an updated image, and performing streak correction between the original image and the updated image to generate a final image. In this way, image quality may be improved without adjusting anatomical structures in an image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for normalizing contrast across multiple acquisitions","description":"Various methods and systems are provided for correcting contrast banding artifacts across multiple acquisitions in reconstructed images.
