Is there an "ideal" method for abdominal motion control when treating upper abdomen malignancies?
In my training, we used an abdominal compression paddle, but in my current practice, my physicist says that we cannot treat through multiple parts of the paddle. This is especially a problem with pancreas, liver, and GE junction tumors since the paddle lies directly anterior to the field.

When giving a BED of <60 Gy, there is no need to use ...
