Table 5.
Measured percent change in the slope-to-intercept ratio of the MTP versus dose line for a variety of MT powers and offset frequencies for the MAGIC dosimeter. For most powers and offset frequencies, the slope-to-intercept ratio does not vary more than 10% for even a 10% error in B1 pulse angle.
