Abstract:
To adjust the Z position of an isocenter IC easily as desired without being limited by the thickness and pitch of a sectional image.
When the position of an isocenter IC is moved by an operator on an image HG where the shape of a radiation field F and the projected shape of a target region T are superposed and displayed, the Z position and X position of the isocenter IC are changed to a moved position as shown in the figure. Thus, while the positional relationship between the radiation field F and the target region T is grasped, the ZX position of the isocenter IC can be adjusted easily and correctly so as to properly execute radiotherapy plan.
