Heart by Contour: How AI Builds 3D Shape
The heart is not a perfect sphere; its shape changes with every beat. To build an accurate 3D copy for a computer model, doctors typically take dozens of MRI slices. But that's like assembling a watermelon from thin slices: the fewer slices, the more guesswork.
A new approach teaches a neural network to understand the heart's shape from sparse contours.
