The data from a single CT scan is comparable to several feature-length films. TCAM-Diff bypasses this bottleneck: the program compresses the 3D scene into three shadow projections — like a sculptor reconstructing a solid statue from silhouettes on three walls. The resulting sketches contain only the essential outlines, but the neural network, like an experienced carver, fills in the missing details and then assembles a complete organ model. A special mechanism constantly cross-checks all three angles to avoid distorting the anatomy — much like an artist alternately looking at sketches from different viewpoints to achieve consistency.

Tests on brain, pancreas, and colon scans showed the method outperforms analogues with the same modest compressed data size. The big surprise: the three shadow projections together take up less space than a single photo on your phone — and that's exactly what paves the way for near-instant 3D diagnostics even on a weak internet connection.
