CARS: a centerline-anchored attention surrogate for coronary blood flow on skeleton-generated lumen geometries
Reza Akbarian Bafghi, Sukirt Thakur, Maziar Raissi
When the parameter of a PDE surrogate is the flow domain itself, the key/value set of an attention model must encode that domain. We present CARS (Coronary Artery Rapid Surrogate),…
Are Learned Vascular Tree Generators Better Than Conditional Resampling?
Reza Akbarian Bafghi, Sukirt Thakur, Maziar Raissi
Fidelity scores compare generated vascular trees with held-out real trees, so by themselves they cannot detect reuse of training data. A training-free conditional resampler shows t…
From Centerlines to Hemodynamics: Anisotropic RBF Decoders for Coronary Arteries
Reza Akbarian Bafghi, Sukirt Thakur, Maziar Raissi
Accurate and rapid estimation of hemodynamic metrics, such as pressure and wall shear stress (WSS), is important for assessing the severity of Coronary Artery Disease (CAD). Existi…
Test-Driven Agentic Framework for Reliable Robot Controller
Shivanshu Tripathi, Reza Akbarian Bafghi, Maziar Raissi
In this work, we present a test-driven, agentic framework for synthesizing a deployable low-level robot controller for navigation tasks. Given a 2D map with an image of an ultrason…
