High Resolution X-Ray Phase Contrast Imaging With Acoustic Tissue-Selective Contrast Enhancement
Abstract
We show that ultrasound can be used for contrast enhancement in high-resolution x-ray imaging of tissue and soft materials. Interfacial features of objects are highlighted as a result of both the displacement introduced by the ultrasound and the inherent sensitivity of x-ray phase contrast imaging to density variations. Experimental results are reported for tumor phantoms. The method produces a directional image that is equivalent to the first space derivative of the phase contrast image along the propagation coordinate of the ultrasound.
