Clinical data set
The TAIR database includes vascular imaging data that represents the critical imaging modalities essential for neurovascular procedures. These modalities are used to visualize the vascular anatomy, identify pathology, and guide procedures. These targeted datasets support workflows connected with the TAIR testbed, and also support community-wide clinical and diagnostic research. A flexible permissive license allows use in academic, government, and commercial applications.
01 – CTA / MRA
A large-scale multi-center compilation of Computed Tomography Angiography (CTA) and Magnetic Resonance Angiography (MRA). All data were collected as part of routine critical care. Prior to release, all data were rigorously de-identified through removal of PHI from the image metadata. Defacing algorithms were applied to remove potentially identifying facial structures.
02 – Fluoroscopy
Videos of X-ray fluoroscopy procedures collected from a multi-center study during interventional procedures. Fluoroscopic videos are paired with CTA/MRA imaging from the CTA/MRA database for multi-modality research and development use cases. Prior to release, all data were rigorously de-identified through removal of PHI from the image metadata. Algorithms were applied to remove potentially identifying facial structures and burned-in text.
03 – Anatomical models
This database includes 100 segmented, centerlined, and annotated CTA/MRA datasets, 50 annotated video fluoroscopy datasets, and models generated from population statistics and shape-modeling techniques.
