Medical imaging data compression utilizing codebooks

Abstract

A system and method for an innovative approach to medical imaging compression and encryption, specifically designed for tomosynthesis data. It transforms input data to a dyadic distribution, optimizing it for Huffman encoding while preserving critical diagnostic information. The compressed data is processed through a Large Codeword Model (LCM) incorporating a latent transformer, which learns complex patterns and relationships within the imaging data. This process not only achieves high compression ratios but also provides inherent encryption. A neural upsampler, trained to invert the dyadic transformation, reconstructs the original image with high fidelity. The system is particularly effective for handling the redundancies inherent in tomosynthesis datasets, where adjacent slices often contain similar information. By balancing compression efficiency with diagnostic accuracy, this method enables secure storage and transmission of large medical imaging datasets while maintaining the ability to reconstruct high-quality images for accurate diagnosis.
