Table 1: Number of ionization chambers located within the field at intervals of dose differences between the measurement and the dynalog-derived response. For comparison, the 2D array measurements and the dynalog-derived responses are renormalized to the central ionization chamber position value for every field. A file is the sum of the result of all fields for a single patient. More than 99.5% of the ionization chambers are within ±3%, and more than 96.5% are within ±2%
