PROCÉDÉS ET APPAREIL POUR TOMOGRAPHIE PAR ORDINATEUR À FAISCEAU EN ÉVENTAIL, TOMOGRAPHIE PAR ORDINATEUR À FAISCEAU CONIQUE ET TOMOGRAPHIE PAR ORDINATEUR À FAISCEAU CONIQUE HYBRIDE, À CONTRASTE DE PHASE DIFFÉRENTIEL
A device for imaging an object, such as for breast imaging, includes a gantry frame having mounted thereon an x-ray source, a source grating, a holder or other place for the object to be imaged, a phase grating, an analyzer grating, and an x-ray detector. The device images objects by differential-phase-contrast cone-beam computed tomography. A hybrid system includes sources and detectors for both conventional and differential-phase-contrast computed tomography.
