Total Body Irradiation with Step Translation and Dynamic Field Matching

Table 2

The dose variation in the overlapped region at various depths measured using EBT3 film strips placed in the solid water phantom slabs. Two dynamic field edges with 3 cm of leaf motion and gantry angles of 11° and 349° delivered a dose to a 20 cm-thick phantom with an overlap of 5.5 cm.

Depth (cm)	0	5	10	15
Dose variation in overlap region (%)	98.4–103.8	99.3–105	97.9–102.3	98.3–101.2
