DICOM-Decoder 1.0.1

1.0.1 - DICOM Streaming & Security Enhancements

New Features

• Add range-based pixel access methods to enable efficient streaming of DICOM image data without loading entire files into memory

• Implement JPEG Lossless decoder with full specification support including Huffman table decoding, first-order predictor, and bit unpacking

• Introduce DicomDecoderProtocol and dependency injection patterns for improved testability and modularity across FileImportService, StudyDataService, and DicomSeriesLoader

Improvements

• Refactor DICOM decoder with modular reader architecture and async support for better separation of concerns

• Optimize range-based reading for memory-mapped file access to improve performance with large DICOM datasets

• Replace print statements with logger.debug for consistent diagnostic output in DCMDictionary

Bug Fixes

• Add comprehensive security validation including bounds checking, sequence depth tracking, pixel buffer allocation validation, and malicious length detection to prevent stack overflow and buffer overflow attacks

• Guard reference decoder test on macOS to handle platform-specific compatibility issues
