Researchers have developed a novel method to reconstruct 3D bone geometry from just two X-ray images, bypassing the need for CT scans or large neural network datasets. The approach utilizes a statistical shape model derived from existing CT scans and employs differentiable rendering to fit the model to the silhouettes from the X-rays. This technique achieved an accuracy of 0.86-1.43mm in leave-one-out validation, though it struggled with bone shapes outside the model's coverage. AI
IMPACT This method could reduce reliance on CT scans for certain medical imaging applications, potentially lowering costs and radiation exposure.
