MLC Usage Approaching 100%

Until July 16, 1999, more than 134500 photon fields were treated at IRO on our two machines. The following graph shows the percentage of MLC for HiX (15MV) and LoX (6MV). For HiX, nearly 100% of all fields are shaped with the MLC (high score: 4107 15MV MLC fields in 6MV is mainly caused by breast March 99). The lower percentage for irradiations (no MLC).
