Скачать или смотреть From 2D Images to 3D Left Atrial Size: A Clever Medical Shortcut

How can doctors estimate the size of a heart chamber without using slow, complex 3D measurements?

In this video, I walk through my science project exploring a clever shortcut used in medical imaging to estimate the volume of the left atrium — an important chamber of the heart linked to conditions like stroke and heart failure.

🔍 What this video covers:

Why left atrial volume matters in medicine
How true 3D heart volumes are measured using MRI segmentation
How a faster 2D area–length method works using just:
two views of the atrium, and one shared length measurement

How this 2D method can approximate a 3D shape by treating the atrium like an ellipsoid

How estimated volumes compare with true 3D volumes using correlation and regression analysis

📊 The project uses open-source cardiac MRI data and simple mathematical models to show that even quick measurements can give surprisingly accurate results.

🧠 This video is aimed at:

students interested in science or medicine
anyone curious about how maths and medical imaging work together
viewers who enjoy accessible explanations of real research ideas
This is an educational project and not intended for clinical use — but it shows how powerful simple models can be when applied carefully.

Thanks for watching!
