Pull request overview
This pull request implements four new command-line tools for the DICOMKit ecosystem: dicom-validate, dicom-dump, dicom-convert, and dicom-anon. These tools provide essential DICOM file manipulation and inspection capabilities. The PR includes comprehensive test suites, documentation (README files), and updates to Package.swift to register the new executable targets. A minor fix to DataSet+TestHelpers.swift addresses a change in how VR information is accessed from the data dictionary.
Changes:
- Added four new CLI tools with ArgumentParser integration for DICOM validation, hex dumping, format conversion, and anonymization
- Created comprehensive test suites totaling over 1,900 lines of test code covering various scenarios and edge cases
- Updated DataSet test helpers to handle VR as an array from dictionary lookups

Default window settings (center: 128.0, width: 256.0) assume 8-bit display range, but DICOM medical images typically use wider dynamic ranges (e.g., 12-bit or 16-bit). This could result in loss of diagnostic information when pixel values fall outside the 0-255 range. Consider calculating a default window based on the actual pixel data bit depth or using a more conservative approach that samples actual pixel values to determine an appropriate range.

The hash function uses Swift's native hashValue which is not cryptographically secure and may not be deterministic across different program runs or Swift versions. For consistent pseudonymization in medical contexts (where the same patient ID should always hash to the same value across sessions), consider using a stable hash function like SHA-256 consistently, even on platforms without CryptoKit.

The deprecated tag warning at (0028,0004) Photometric Interpretation is incorrect. This tag is NOT deprecated in DICOM - it's a required Type 1 attribute for image IODs. The comment "is deprecated in some contexts" is misleading and could cause confusion. This validation check should be removed or corrected to check for actual deprecated tags.

There was a problem hiding this comment.
The isValidTagPattern function always returns true for any group >= 0x0003, which means it will accept completely invalid byte sequences as tags during hex dump annotation. This can lead to false positive tag detection and confusing output. Consider adding more sophisticated validation such as checking if the VR bytes form a valid VR string, or checking against known tag patterns from the DICOM dictionary.

The validateFile and validateDirectory methods are marked as async but don't contain any actual asynchronous operations (no await calls). This is unnecessary overhead and misleading API design. Consider removing the async keyword from these methods unless there are plans to add actual asynchronous operations (like concurrent file processing).

The tag search implementation uses a simple linear scan through raw file data and makes assumptions about explicit VR encoding. This approach is fragile for files with implicit VR encoding or compressed transfer syntaxes. The comment acknowledges this is "simplified" but the tool could fail or produce incorrect output for such files. Consider adding better transfer syntax detection or documenting this limitation more prominently.

The date validation only checks basic range constraints (year 1900-9999, month 1-12, day 1-31) but doesn't validate actual calendar validity. For example, it would accept February 31 or April 31 as valid dates. Medical imaging data requires accurate date validation for longitudinal studies and regulatory compliance. Consider using proper calendar validation to reject impossible dates.

The conversion logic doesn't handle compressed transfer syntaxes (like JPEG, JPEG 2000, RLE). When converting from or to compressed syntaxes, the pixel data needs decompression/compression which is not implemented. The code will attempt to write compressed pixel data as-is with a different transfer syntax UID, resulting in invalid DICOM files. Either add compression/decompression support or explicitly reject unsupported transfer syntax conversions with a clear error message.

Similar to dicom-validate, the convert methods are marked as async but don't contain any actual asynchronous operations. This adds unnecessary complexity and doesn't provide any performance benefits. Consider removing the async keyword or implementing actual concurrent processing for batch operations.

scanForPHILeaks builds warning messages that embed the first 20 characters of values detected as potential PHI, which are later printed by the CLI, leaking sensitive patient information to stdout/logs. An attacker (or any log consumer) can recover portions of names, IDs, or other identifiers from these warnings, defeating anonymization guarantees. To fix this, avoid including any part of the original value in warnings (only reference the tag or a generic marker) so that PHI never leaves the DICOM payload during anonymization.

| warnings.append("Potential PHI detected in private tag \(tag); value omitted to protect privacy.") |
- Add dicom-query executable target to Package.swift - Implement main.swift with ArgumentParser support - URL parsing (pacs:// scheme) - Query filters (patient name, ID, date, modality, etc.) - Multiple query levels (patient, study, series, instance) - Output format selection (table, JSON, CSV, compact) - Verbose mode for debugging - Implement QueryExecutor.swift - Uses DICOMQueryService from DICOMNetwork - Builds QueryConfiguration with AE titles - Executes C-FIND queries at all levels - Implement QueryFormatter.swift - Table format with aligned columns - JSON format for scripting - CSV format for spreadsheets - Compact one-line format - Date formatting (YYYYMMDD to YYYY-MM-DD) - UID shortening for readability - Add comprehensive unit tests (27 tests) - URL parsing tests - Query level mapping tests - Query key building tests - Formatter tests for all output formats - Integration test placeholders - Add detailed README.md with usage examples Co-authored-by: SureshKViswanathan <257696045+SureshKViswanathan@users.noreply.github.com>
Extract common configuration logic into buildConfiguration() helper method. Remove duplicate queryPatients/queryStudies/querySeries/queryInstances methods. Simplify executeQuery to directly call DICOMQueryService.find().
- Created dicom-send executable for C-STORE file transfers - Implemented SendExecutor with retry logic and exponential backoff - Added ProgressReporter for real-time transfer tracking - Support for single files, multiple files, and recursive directories - Glob pattern support (*.dcm, CT_*.dcm) - Dry-run mode for testing without sending - Comprehensive unit tests (27 test cases) - Complete README with usage examples - Updated Package.swift with dicom-send target This is the 7th and FINAL CLI tool, completing the CLI Tools Suite! Co-authored-by: SureshKViswanathan <257696045+SureshKViswanathan@users.noreply.github.com>
All 7 CLI tools are now complete: - 160 total test cases - All builds passing - Comprehensive documentation CLI Tools Suite is COMPLETE! 🎉 Co-authored-by: SureshKViswanathan <257696045+SureshKViswanathan@users.noreply.github.com>
