[Gate-users] Model for bowtie filter for fan-beam CT in GATE

[Alejandro Coloma]

Dear S, Megha Singh

If you have the information about the shape of the bow-tie filter (i.e. the
height h=h(x) of the filter in the fan plane, or its angle dependence), you
can use the wedge geometrical shape, which is available in GATE, to
construct the whole filter as a sum of many wedge bodies with tiny
x-dimensions to approximate the real shape of your filter.

Best regards,
Alejandro Coloma
