Tumor tracking: DMLC

Advantages

:

Ø

Using the available dynamic MLC mode for tumor pursuit

Ø

Use of full field size

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?

Static

Not-tracked

Tracked

MLC
