Abstract: A system and method for imaging a volume having a detector including a first atomic species with an absorption edge at a first wavelength. The system also includes a source having a second atomic species for emitting an ionizing energy. The second atomic species has a characteristic emission peak that substantially matches the absorption edge of the detector. A filter may be provided for blocking ionizing energy from the source in regions other than a region proximate the characteristic emission peak. Effective imaging with a lower radiation dose may be achieved with the system and method.

Abstract: A system and method for imaging an object that takes into account movement of the object in producing an MR image. A system may include a target volume location sensor for determining a location of an object being imaged. A moving-target algorithm may use the location information and other image information to match appropriate data to construct an image of the object. A moving-target algorithm may use the location information to provide instruction on changing a gradient field of an imaging system to account for a location of an object.
