Figure 1From: Dosimetric comparison of 4 MeV and 6 MeV electron beams for total skin irradiationPositions of treatment apparatus gantry used to generate a dual field for the anterior body position in TSEI. The spoiler was only used for 6 MeV TSEI beam. The gantry angle (θ) was ± 18.5° and 90 ± 18° for 4 MeV with no spoiler and 6 MeV with spoiler, respectively.Back to article page
