      Since IMRT uses a combination of small beamlets, it yields higher monitor units (MU) than required for three-dimensional conventional radiotherapy (3D-CRT) to deliver the same prescribed dose to patients (Haertl et al., 2013; Wolff et al., 2009; Liu et al., 2017; Palma et al., 2008). The average MU ratio per absorbed dose of IMRT to the average MU per absorbed dose of the existing 3D-CRT is called the IMRT factor, and it affects the leakage dose (Followill et al., 1997; Mohan et al., 2000; Mutic et al., 2001). According to the existing literature, the IMRT factor is described in the range of 2–10, but exceeds 10 in some cases (Afrin and Ahmad, 2020; Mutic and Low, 1998; Rodgers, 2001; Webb, 2000).
