%X <em>Aims</em>: This study compares data between the Field in Field planning and Wedge planning techniques to figure out which technique has better dose coverage and distribution for PTV, and, if using FiF technique for whole brain treatment, how many beams will have better plan. <em>Methods</em>: 56 patients, who need to radiate whole brain with 30 Gy/10 fractions, have been selected for this study. Four plans have been made for each patient (FiF1¡ªone subfield per field plan, FiF2¡ªtwo subfields per field plan, FiF3¡ªthree subfields per field plan, and a Wedge plan). <em>Results</em>: The results of Field in Field plans including C<em>ompare dose distribution on the transverse CT slice, plan evaluation using DVH, number MU of plan, D<sub>max</sub>, HI, HTCI, D<sub>maxPTV</sub>, D<sub>meanPTV</sub>. Volume of PTV with the dose over 105% prescribed dose, dose of organ at risk, and Quality Assurance (QA) plan</em>, are better than those of Wedge plan. <em>Conclusions</em>: Plans using Field in Field technique has better coverage, is more homogeneous in dose distribution than plan using Wedge technique. When using Field in Field technique for whole brain radiotherapy, using three subfields per field has better result than two subfields per field and one subfield per field.
