dicom_parser - DICOM Parser in Flutter (Dart) #

This project is a fully Dart-based DICOM parser, developed entirely using the Flutter framework. It enables cross-platform parsing and rendering of DICOM medical images across mobile, web, and desktop applications — without relying on native C/C++ libraries.

The parser supports reading, decoding, and interpreting core medical imaging data, making it a powerful tool for developers building health-tech applications.

Platform Support #

Features #

• 📂 Parse DICOM files
• 🔄 Support for various Transfer Syntaxes
• 🎨 Support for multiple Photometric Interpretations
• 💻 Works on Android, iOS, Web, macOS, Linux, and Windows
• ❌ No native dependencies — 100% Dart

Supported Transfer Syntaxes #

Supports a wide range of DICOM Transfer Syntax UIDs for uncompressed and compressed image data:

• 1.2.840.10008.1.2 — Implicit VR Little Endian
• 1.2.840.10008.1.2.1 — Explicit VR Little Endian
• 1.2.840.10008.1.2.2 — Explicit VR Big Endian
• 1.2.840.10008.1.2.5 — RLE Lossless
• 1.2.840.10008.1.2.4.50 — JPEG Baseline (8-bit)
• 1.2.840.10008.1.2.4.51 — JPEG Extended (12-bit)
• 1.2.840.10008.1.2.4.57 — JPEG Lossless (Non-Hierarchical)
• 1.2.840.10008.1.2.4.70 — JPEG Lossless (First-Order Prediction)
• 1.2.840.10008.1.2.1.98 — Deflated Explicit VR Little Endian

Supported Photometric Interpretations #

• MONOCHROME1 — Inverted grayscale (0 = white)
• MONOCHROME2 — Standard grayscale (0 = black)
• RGB — Color images
• PALETTE COLOR — Indexed color with LUTs
• YBR_FULL — YUV color encoding (JPEG-related)

Usage #

import 'package:dicom_parser/dicom_parser.dart';
import 'dart:typed_data';

Uint8List? fileBytes;

// Read DICOM file bytes into fileBytes

DICOMModel dicomModel = await parseDICOM(fileBytes);

// Parsed tags from DICOM File
List<TagModel> tags = dicomModel.tags;

// Parsed Image as Uint8List that can be  used in Image.memory() to view in flutter widget
Uint8List? parsedImageBytes = dicomModel.imageBytes;

// Get Modality of DICOM File
String? modality = dicomModel.getModality();
