3 basic application of MLCs
1.To replace conventional blocking
2.Matching the BEV to PTV during an arc rotation of X-ray beam
3.Achieve beam intensity modulation
1.upper jaw replacement
2.lower jaw replacement
3.tertiary MLC

Tungsten alloy(tungestan,Fe,Cu,Ni) is the material of choice for leaf construction because:
High density Hard Inexpensive low coefficients of expansion density of Pure tungsten= 19.3 g/cm3 density of the alloys =17.0- 18.5 g/cm3
