Is ASTRO worth exhibiting?
Why Exhibit
The definitive conference for radiation oncology and medical physics. If you sell linear accelerators, proton therapy systems, treatment planning software, radiation protection, or brachytherapy equipment, ASTRO is where department-level purchasing decisions begin. Medical physicists, who heavily influence capital equipment selection, attend in force.
Why Skip
Very narrow audience. Non-radiation-oncology devices have no buyer here. The $49/sqft rate plus $2,000 island surcharge makes it expensive for the audience size. Capital equipment companies (Varian, Elekta, Accuray) dominate the floor.
What should exhibitors know before ASTRO?
ASTRO is dominated by the big 3 (Varian/Siemens, Elekta, Accuray) but there is real opportunity for treatment planning software, QA tools, patient positioning, radiation protection, and AI/ML companies. Product Showcases at $3,500 are an underused option for startups to present without a full booth. Boston BCEC is a union venue. Plan for drayage and labor. A. Fassano & Co manages both ASTRO and HRS. If you exhibit at both, leverage the relationship.
