Exempel på gantry

• However, time optimal feedback designing is a difficult problem for a gantry crane and this problem is not yet solved.

• The possibility to render the elastic vibrations as small as desired is proved analytically for a gantry crane with a payload.

• This should be done for a range of depths and for treatment beams at a range of gantry angles.

• No significant difference between the gantry tilting and half beam block techniques was demonstrated.

• It has launched a 3 to 5 axis gantry-robot for industrial production of large and specific complex parts for special applications in the aeronautic industry.

• The motion of a gantry crane under the designed feedback control is not far from the time optimal motion.

• Production of ion beams in high-power laser-plasma interactions most of the gantry, which provides multidirectional irradiation of a lying patient, is no longer required.

• Therefore, in our opinion, the problem of the controller design is for a gantry crane not closed.

• However, by law the gantry can only complete one 360° rotation in a maximum of 1 minute, this therefore means that image acquisition is slow.

• One other difficulty was air movement above the water and mechanical vibration through the table structure, probe mount and gantry.

• The gantries themselves are more imposing structures than linear accelerators and can enclose patients as much as helical tomotherapy equipment.

• The couch was moved 500 mm into the gantry and the offset from the marker recorded: this was found to be <1 mm.

• A common arrangement of five beams, each separated by equal gantry angle, was adopted.

• The point of intersection between the gantry axis of rotation and the beam is called the "isocenter".

• For a prosthesis on the left side, the gantry angles are approximately 30, 150, and 270 degrees.
