Tumor tracking: DMLC

• Advantages : Ø

Using the available dynamic MLC mode for tumor pursuit

Use of full field size

Ø Ø

Little compromises for other classic treatments

• Drawbacks : Ø

Only useable with a flattened beam, what with FFF?

Ø Tracking and DMLC intensity modulation are coupled: coupled constraints and increased complexity with higher modulation and higher velocities Ø Tracking perpendicular to MLC leaf tracks?
