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.
