摘要
PURPOSE: A multidimensional phantom for controlling qualities of a stereotactic body radiation therapy and an intensity modulated radiation therapy is provided to enable to measure multidimensional radiation dose for applying radiation from one phantom to various simulating human bodies, thereby increasing a success rate of the radiotherapy by easily and accurately confirming the amount of the radiation dose. CONSTITUTION: A multidimensional phantom(1) for controlling qualities of a stereotactic body radiation therapy and an intensity modulated radiation therapy comprises a movable body(200), a fixed body(100), and a movable body adjusting lever(300). An ionization chamber(20) is formed in one side of the movable body in a body-axial direction of the multidimensional phantom so that an ion chamber for measuring a one-dimensional distribution of a radiation dose is inserted into the movable body. The fixed body is mounted so that the movable body is movable. The movable body adjusting lever moves the movable body to be spaced from the fixed body at a predetermined distance or fixes the spaced movable body to the fixed body.
