Figure 1From: Independent absorbed-dose calculation using the Monte Carlo algorithm in volumetric modulated arc therapyComputed tomographic image of the water phantom (RT-3000-New-Water, R-Tech, Japan) mapping a dose distribution. This phantom permits the insertion of a 0.6-mL ionization chamber at the locations indicated as (isocenter), and 3 cm to the left and right and 3 cm above and below the isocenter.Back to article page
