US 7,352,885 B2 · Method and system for multi-energy tomosynthesis

Abstract

Briefly in accordance with one embodiment, the present technique provides a multi-energy tomosynthesis imaging system. The system includes an X-ray source configured to emit X-rays from multiple locations within a limited angular range relative to an imaging volume. The imaging system also includes a digital detector with an array of detector elements to generate images in response to the emitted X-rays. The imaging system further includes a detector acquisition circuitry to acquire the images from the digital detector. The imaging system may also include a processing circuitry configured to decompose plurality of images based on energy characteristics and to reconstruct the plurality of images to generate a three-dimensional multi-energy tomosynthesis image.
