Correlation of several prescription and reporting methods. All methods report for the same dose distribution per study. -- Non-breast cases. The upper value in each cell is the mean value; the lower value is the corresponding standard deviation. ICRU RD: ICRU Reference Dose; PTV₅: PTV shrunk by 5 mm; Case mean: Mean value of four (IMRT with a single PTV: five) points suitable for dose description according to ICRU 50/62
