METHOD OF MEASURING TWO-DIMENSIONAL DISTRIBUTION OF RADIOLOGICAL DOSE USING 3D PHANTOM

WIPO Patent Application WO/2011/093183

A1

Disclosed is a method of efficiently and accurately measuring the two-dimensional distribution of radiological dose using a 3D phantom with high reproducibility. The method comprises a step of holding a radiation-dose measuring body such that the measuring body is in a horizontal position between the 3D phantom that are formed of upper and lower separable bodies and of which cross-sectional shapes are symmetric with respect to 90°; a step of measuring a dose distribution in the coronal plane by emitting radial rays onto the 3D phantom that holds the radiation-dose measuring body in a horizontal position using gantries of a radiotherapy device; and a step of measuring a dose distribution in the sagittal plane by emitting radial rays onto the 3D phantom after the gantries are rotated by 90° without changing the position of the 3D phantom.
