Various [human] whole body, multiple field, electron beam therapy techniques are analyzed. Accelerator characteristics, various dosimetric techniques and experimental setup are described. A flattening filter was constructed which produced an uncollimated electron beam profile (4 MeV) with a uniformity of .+-. 8% across a 200 cm diameter area at 7 m from the source. Irradiation techniques include 2-, 4-, 6- and 8-field therapy and rotation. Conclusive evidence is presented to support adoption of the 8-field technique or rotation as the methods of choice for superfical whole body treatment of mycosis fungoides and other skin lymphomas.
