We receive requests directly or via submission online through the SAR website, we look at the institutional representative from that institution if any and whether we have additional roles for new members to fill.
They will participate in quarterly meetings, join one working group and one committee and be able to collaborate with all members for research projects, collaborate with other relevant SAR DFPs/ETC and other societies on ultrasound topics.
We don’t have a cap but wanted to keep it a manageable group with enough tasks to distribute, a rough number is around 20 and as a new ETC we initially had more interest than we felt we had room for but have since then added 4 of these members, all more early career.
