Abstract: Machine for drawing metal sheets, which comprises a static support (3) and a moving support (4) that hold a metal sheet (2) during a process of drawing said metal sheet (2), and driving means (5) that cause a longitudinal movement of said moving support (4) in relation to said static support (3) during said process, a section (S) of said metal sheet (2) comprised between said supports (3, 4) being drew and tensioned. Said machine (1) also comprises a third support (6) that remains static during the drawing process and which is disposed between the static support (3) and the moving support (4), and the driving means (5) cooperate with said third support (6) in order to move said moving support (4) longitudinally during said drawing process.

Abstract: A method of treating an object with radiation that includes generating volumetric image data of an area of interest of an object and emitting a therapeutic radiation beam towards the area of interest of the object in accordance with a reference plan. The method further includes evaluating the volumetric image data and at least one parameter of the therapeutic radiation beam to provide a real-time, on-line or off-line evaluation and on-line or off-line modification of the reference plan.
