Hello, </p>
<p dir="ltr">Can someone recommend a solution for incorporating important structures into the Gate model. Specifically, </p>
<p dir="ltr">1) I would like to design an Antiscatter grid such as those commonly used in fan beam or cone beam CT. I would like to design a focusing type Collimator, but there is some difficulty as geometry editor does not permit anything more than basic geometries. I was considering a tall trapezoid, and performing a ring pattern operation to generate a focusing type grid, but this is not correct because a ring operation would give the antiscatter grid some radius, creating a gap between the detector and anti scatter grid. </p>
<p dir="ltr">2) I would like to use some standard phantoms. I feel this has probably already done. Is there some place I can download geometry? </p>
<p dir="ltr">Cheers </p>
