bull's eye plot
Standardized polar map display format showing left ventricular segments in a circular diagram for regional analysis of cardiac function and perfusion.
Full Definition
A bull's eye plot is a specialized data visualization technique that presents all 16 or 17 American Heart Association standard left ventricular segments in a single circular diagram. The format displays the heart as if viewed from the apex, with the anterior wall at the top and the inferior wall at the bottom. Each segment is color-coded or shaded according to measured parameters such as perfusion, wall motion, or strain values. This standardized presentation allows for rapid visual assessment of regional abnormalities and facilitates comparison between different imaging modalities and time points. Bull's eye plots are commonly used in nuclear cardiology, echocardiography, and cardiac MRI reporting.
Usage
Usage note: Use apostrophe in bull's eye; avoid bullseye as single word in formal medical reporting.
