Guide to AI at AAPM Annual 2026
A field guide to artificial intelligence at the AAPM | COMP Annual Meeting & Exhibition — one agenda of sessions and committee meetings worth your time, which exhibit-hall products are worth a real look, and where AI policy for the field actually gets written.
A decade of AI at AAPM
Up from 1 in 2017. Peaked at 21 in 2025.
Zero before 2024. Large language models and foundation models are the newest AI subfield with a standing claim on the program.
Down from a peak of 8 in 2022 (faded ring) to 1 in 2026 (bold ring). Not because the work stopped — because "AI" absorbed it as the umbrella term.
Down from a peak of 4 in 2018 (faded ring) to zero in 2026 — no bold ring left at all. No named session since 2022; same story, different label.
Down from a peak of 9 in 2021, holding at 2–3 since. Auto-contouring and auto-planning are arguably the most clinically deployed AI in the room — just no longer novel enough for a headline.
Sessions & committees to attend
One agenda — the AI-focused scientific sessions and the AAPM committee rooms where policy for the field gets written, in the order they actually happen. Filter by priority or by type, then add anything straight to your calendar.
Which booths to visit
Ranked by genuine novelty first, recency second — a product that does something no prior commercial system did outranks a routine model update, even a very recent one. Built from vendor filings, FDA clearances, and trade press, not booth-copy marketing claims.
Real-time AI scatter correction running during CBCT acquisition, not after — pushes cone-beam CT toward sub-10-second, diagnostic-quality imaging and unlocks routine adaptive RT on more machines.
Marketed as the world's-first AI-powered detector-based spectral CT — deep-learning reconstruction fused with an always-on spectral detector, cleared for RT planning use as well as diagnostic radiology.
The AI is familiar zero-click auto-contouring — the notable part is that FDA clearance now includes a Predetermined Change Control Plan, letting future model updates ship without a fresh 510(k) each time. Cleared roughly six weeks before AAPM.
Adds AI-assisted "Identify" motion management and dynamic-couch upgrades on top of fast HyperSight CBCT, extending Halcyon's adaptive handling to more complex cases.
Merges two previously separate commercial auto-contouring products — AutoContour and the acquired Limbus Contour — into one platform: 480 combined AI models and a new browser-based "Zero-Click" workflow.
ECHO, an automated planning algorithm developed at Memorial Sloan Kettering, is now fully integrated, alongside continually expanding deep-learning segmentation. Real but incremental growth on an already-mature platform.
AI-driven auto-contouring, part of a broader planning and QA suite. No specific 2025/26 feature breakthrough surfaced in our research — included because Manteia is confirmed exhibiting with an AI-labelled product.
The reference point for AI-driven online adaptive RT. Base platform since 2021; the HyperSight integration that expanded it to 70+ auto-contoured structures cleared July 2024 — outside this year's window, but still worth seeing live if you haven't.
Real-time markerless motion tracking on Radixact and CyberKnife. By Accuray's own account, the underlying technology is over two decades old — continuously refined rather than newly launched.
