A new computer method for cleaning up noisy CT scans works better than other methods, making the images clearer by up to 17% in sharpness and 38% in structural detail quality.
A special part of the cleaning method uses CT scan projection data to help preserve important anatomical details and textures in the cleaned-up images.
Training the cleaning method in two steps (first on many different scans, then on specific types of scans) makes it work better across different body parts and scan types.
A special part of the cleaning method uses a transformer-based system to analyze CT scan projection data, capturing both small details and overall patterns for better image cleanup.
A special part of the cleaning method creates custom instructions for the image cleanup process based on the CT scan's features, helping to preserve important anatomical details.
