You could just change the surface of of the source from 0.02 mm2 to 200 mm2 to make it equal to the surface of the irradiation field.

<br>
Hi Asra,<br>
<br>
Are you simulating a CBCT like scanner? If yes here a 120 kVp X-ray spectra covering a uniform rectangular field of view, which I built few years ago, to change the irradiation field you need to change irradiation angle and the source to FOV center distance.<br>
<br>
Hope it helps,<br>

<br>
Does anyone else know how to simulate a source with rectangular cross section without using beam collimation.<br>
<br>
<br>
Thanks & Regards<br>
