Abstract

Physics and radiographer QC procedures are urgently needed as the first few contrast-enhanced dual energy systems have been installed in the U.K. Preliminary work on one commercially available system has enabled us to propose new tests, relevant to the properties of dual energy imaging systems. Results are presented for measurements with the chosen phantom, which contains disks with a range of iodine content from 0.25 to 2 mg/cm2. Breasts of different thicknesses and different glandularity were simulated by adding slabs of CIRS material, of a range of compositions, on top of the phantom. The system tested had a response which was proportional to the iodine content of disks in the phantom, had good reproducibility, and did not change significantly when simulated breast thickness and composition were varied.
