Abstract:
1. A hadron therapy device comprising: a rotatable gantry and a patient positioning imaging device configured to position a patient, said patient positioning imaging device comprising an imaging beam source, an imaging beam receiver, and a rotatable structure provided with an extensible arm or a foldable pivot arm configured to connect said imaging beam source and an extensible structure or a foldable pivoting structure configured to carry said imaging beam receiver, whereby said rotatable structure is configured to take CBCT shots of said patient while said patient is located in an offset position with respect to an isocentre of said hadron therapy device, said offset position being in the direction of a rotational axis of said rotatable gantry, whereby said rotatable structure is configured to be rotated while said rotatable gantry remains fixed, and while said extensible or foldable pivoting arm and said extensible or foldable pivoting structure are in extended or unfolded position, wherein said rotatable structure is mounted on the rear of said rotatable gantry.
