Comparison with MLC based CFIMRT and non-MLC CFIMRT

Left pelvic mass (Lymphoma)

 Residual mass after several chemotherapy is seen at Pelvis. I treat him by MLC based CFIMRT. But I made another plan without MLC to the trial. All ports are coplanar.


Its dose distribution is very good. Indeed, let's compare to MLC-based CFIMRT plan.

1: Non-MLC CFIMRT                             2:MLC-based CFIMRT

There are no superiority or inferiority in both plan. In some cases, you are maybe able to plan well without MLC.
