Abstract
An imaging phantom for contrast imaging calibration. The phantom includes a body defining at least one cavity having a directional configuration corresponding to at least one pre-determined direction of motion of the phantom. The phantom also includes at least one imaging capsule configured to match and be contained in the at least one cavity. The imaging capsule comprises a material having an imaging contrast different from that of the body.
Claims16
An imaging phantom for contrast imaging calibration, the phantom comprising:
- a body defining a plurality of cavities, the cavities each having a directional configuration corresponding to at least one pre-determined direction of motion of the phantom;
- and
- at plurality of imaging capsules configured to match and be contained in respective cavities, the imaging capsules each comprising a material having an imaging contrast different from that of the body, the imaging capsules each having different densities, the different densities being selected to produce imaging contrast enhancements representative of different concentrations of a contrast agent.
An imaging phantom for contrast imaging calibration, the phantom comprising:
- a body defining at least two cavities;
- and
- at least two imaging capsules configured to match and be contained in respective ones of the at least two cavities, the imaging capsules comprising respective materials having an imaging contrast different from that of the body, the imaging capsules each having different densities, the different densities being selected to produce imaging contrast enhancements representative of different concentrations of a contrast agent.
