Abstract: Novel and advantageous systems and methods for performing X-ray imaging by extracting X-ray phase-shift and/or dark-field information through a detector that has built-in G2 functionality are provided. Grating translation can be replaced by an electrical operation in the detection procedure, thereby eliminating the need for the analyzer grating and the typical mechanical stepping process.

Abstract: Novel and advantageous methods and systems for performing spectral computed tomography are provided. An edge-on detector, such as a silicon strip detector, can be used to receive X-rays after passing through a sample to be imaged. An energy resolving process can be performed on the collected X-ray radiation. The CT scanner can have third-generation or fourth-generation geometry.

Abstract: Novel and advantageous methods and systems for performing computed tomography (CT) imaging are disclosed. Electrodes can be connected to appropriate surface sites of a detector element of a CT scanner to capture nearby electron-hole pairs generated by X-rays received on the detector element. This detection can be performed in current-integrating/energy-integrating mode.
