>Scan Mode​

(300A,0308)​

1​

The method of beam scanning used during treatment.​

Defined Terms:​

NONE​

No beam scanning is performed.​

UNIFORM​

Between control points, the beam is scanned to​

create a uniform lateral fluence distribution across​

the field.​

MODULATED​

Between control points, the beam is scanned to​

create a modulated lateral fluence distribution​

across the field.​

create a modulated lateral fluence distribution​

across the field. The specific scan mode is defined​

by Modulated Scan Mode Type (300A,0309).​

position begins when the spot is at the previous spot​

position but the spot moves as quickly as possible to the​

currentspecifiedspotpositionwheremostoftheMeterset​

is delivered.​

LINEAR​

The beam spot is delivered with uniform flux while​

traveling from one position to the next position​

(continuous).​

MIXED​

Between control points the beam may be delivered by a​

combination of STATIONARY, LEAPING or LINEAR​

modes.​
