An imaging system (200) includes a radiation source (208) that emits radiation that traverses an examination region. The imaging system further includes a hybrid data acquisition system (212) that receives radiation that traverses the examination region. The hybrid data acquisition system includes a phase-contrast sub-portion (304) spanning a sub-portion of a full field of view. The hybrid data acquisition system further includes at least one of an integrating portion (302, 702, 804, 806, 902) or a spectral portion (402, 704, 706, 802, 1002) spanning the full field of view. The hybrid data acquisition system generates a phase-contrast signal and at least one of an integration signal or a spectral signal. The imaging system further includes a reconstructor (216) that reconstructs the phase-contrast signal and at least one of the integration single or the spectral signal to generate volumetric image data indicative of the examination region.
