摘要: Methods and apparatus for producing an image of an object with a multi-slice imaging apparatus having a row of detectors are provided. The method includes generating a first partial image using projection data acquired at a first imaging position in a step-and-shoot imaging mode, generating a second partial image using projection data acquired at a second imaging position, and combining the partial images to form a final image.

摘要: Method and apparatus for locally enhancing image data represented as pixels having CT numbers is provided. The image data includes bony structures, and the method comprises segmenting pixels within the image data into areas based on the pixel's CT number. A first area represents a combination of soft tissue and lower density bones and a second area represents higher density bones. A subset of pixels is identified within the first area representative of the lower density bones. An enhancement is applied to the subset of pixels within the first area and to the second area to create an enhanced dataset, and a locally enhanced image is generated based on the image data and the enhanced dataset.
