Parameters of the multileaf collimator of Axesse (Agility)

Parameter	Value
Field size maximum	400 mm
Leaf individual travel range (with respect to DLG)	200 mm
Leaf interdigitation range	200 mm
Leaf and DLG combined travel range	350 mm
Diaphragm/jaw overtravel relative to central axis	120 mm
Diaphragm/jaw speed, maximum	$90\hspace{0.17em}\text{mm}/\mathrm{s}$
Leaf speed, maximum	$35\hspace{0.17em}\text{mm}/\mathrm{s}$
Leaf and DLG combined speed, maximum	$65\hspace{0.17em}\text{mm}/\mathrm{s}$

$\text{DLG}=\text{dynamic leaf guides}$; all leaves were integrated with two DLGs and they traveled together.
