 ## 📋 Overview
 
-This dataset supports the paper **"PPCNet: Projection-Conditioned Point Cloud Reconstruction of the Lumbar Spine from Biplanar Radiographs"**. It provides paired biplanar DRRs, calibrated 3×4 projection matrices, and dense ground-truth point clouds for **1,037 patients** with complete L1–L5 lumbar vertebrae, derived from the publicly available **VerSe'19**, **VerSe'20**, and **CTSpine1K** collections.
