Estimating the term…
The present invention is related to a method for treating or irradiating a target volume with a particle beam produced by an accelerator, comprising the steps of: deflecting said particle beam with the help of scanning means in two orthogonal (X, Y) directions, thereby constituting an irradiation plane perpendicular to the direction (Z) of the beam, defining in the irradiation plane a scanning field which circumscribes the area of intersection of target volume and irradiation plane and scanning said scanning field by drawing scan lines which form a scan pattern comprising interleaved frames of triangle waves. The scan pattern is preferably continuous and represents contiguous rhombi figures. The invention is equally related to a device and a software program or sequencer implementing the method.
A method for irradiating a target volume with a particle beam produced by an accelerator, comprising the steps of:
An apparatus for irradiating a target volume through a particle beam produced by an accelerator, wherein the particle beam generates a spot located within the target volume, with the spot being associated three coordinates (x,y,z), the coordinate (z) corresponding to beam direction Z while coordinates (x,y) correspond to directions X and Y orthogonal to the direction Z and to one another, the x and y coordinates being obtained with a scanning device deflecting the particle beam along directions X and Y while the z coordinate is obtained with an energy variation device, wherein the apparatus comprises a control device adapted to control continuously the scanning device in order to allow the spot to be scanned in the X, Y plane according to a scan pattern comprising a multiple of two interleaved frames of triangle waves.
