<div dir="ltr">If you are doing any real experiments with the Hoffman brain phantom, I believe you can get the original digital version of the phantom image from the manufacturer, and then you can convert it to the specific format for simulations. And that should be exactly the same version as the physical one you are using for experiments, no matter in size or resolution.<div><br></div><div>Best,</div><div>Xinjie</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Mar 24, 2022 at 10:29 AM Daniel Bonifacio <<a href="mailto:daniel.bonifacio@ipen.br">daniel.bonifacio@ipen.br</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi Xinjie,<div><br></div><div>Thanks for your reply.
