A new calibration phantom for quantitative computed tomography.
We report on a new calibration phantom for quantitative computed tomography which has been improved with respect to reference materials and geometrical setup. Instead of liquid calibration solutions, we use polyethylene-based water- and bone-equivalent plastics. The size of the phantom is considerably reduced by using only two samples. This design guarantees long-term stability and it offers advantages with respect to radiation geometry.
