In conclusion, we have presented for the first time the use of VIPAR gel dosimeters for dose measurements in multi-detector CT scanners. Our results show that VIPAR gel dosimeters can be used to determine beam width dose profiles and calculate the z-axis geometric efficiency of the modern multi-detector CT scanners. Measurements of all the available beam width dose profiles can be performed as a part of the acceptance tests and the quality assurance of modern CT scanners. Further research work is required in manufacturing polymer gels with improved sensitivity in the diagnostic energy region doses.
