ITK-Snap’s main offering is manual segmentation tools (eg. It was created as the result of a long-term collaboration between researchers at PICSL at the University of Pennsylvania, and the Scientific Computing and Imaging Institute (SCI) at the University of Utah, and as a result has a heavy academic following. ITK-Snap is another open-source medical imaging annotation tool – unlike some of the others we will cover in this article, it is focused exclusively on one step of the broader data annotation process: the segmentation task. MTIK, and the subsequent open-source workbench tool, were originally developed for and by PhD students and researchers in the Division of Medical and Biological Informatics (MBI) of the German Cancer Research Center. Here’s more information about how you can use the MTIK Workbench for medical imaging annotation and segmentation projects. The source code is stored in GitHub and there is MTIK Workbench software that anyone can download and use for Windows, Linux, and Mac (macOS). It’s based on The Medical Imaging Interaction Toolkit (MITK), “open-source software for the development of interactive medical image processing software.” MITK Workbench is a free open-source software for medical image processing, annotation, and segmentation. In this article, we will focus on several of the most popular, including MITK Workbench, ITK-Snap, 3D Slicer, HOROS, OsiriX, and the OHIF viewer. What are Some of the Most Popular Medical Imaging Open-Source Annotation Tools?Ī wide range of open-source tools support, and were specifically created to, manage annotation projects for medical image datasets. Now let’s take a closer look at some of the most popular open-source annotation tools on the market. In most cases, they support an array of medical image file formats (including DICOM and NIfTI medical image file formats).They typically support community and academic use cases alike.They are available for commercial use and can be built upon and customized.The key advantages of open-source annotation tools for medical imaging are: What are The Advantages of Using Open-Source Annotation Tools for Medical Imaging? Tools are often tested using publicly available medical imaging datasets, and are usually financially supported by a charitable foundation, public/users donations, or one or more tech company sponsors. Open-source tools are usually built collaboratively, with numerous - sometimes hundreds or thousands - of developers contributing to the source code. They will be aimed at supporting almost any image or video annotation purpose (unless the license specifically prohibits a certain type of use). When we think of annotation platforms, what we mean by open-source annotation tools are tools that help teams with the broad annotation and labeling process (including use cases like image classification, image segmentation, data labeling, and object detection). Open-source annotation tools are software programs whose source code is freely available for anyone to use. In this article, we will cover several of the most popular open-source tools for medical image annotation, including the key use cases, benefits, and downsides of these tools – we will also look ahead to what’s next after getting started with these tools, and considerations that teams make as they go forward in their data annotation journey. When conducting your own evaluation, it’s worth comparing what is on the market with what your own requirements are – based on your specific use cases and forward-looking plans. We will mainly cover a handful of tools designed to solve specific medical image annotation pain points and problems, such as MITK Workbench, ITK-Snap, 3D Slicer, and several others, rather than broader-ranging computer vision annotation tools.Īs we all know, there are pros and cons to using open-source tools for medical image annotation projects. In this article, we will cover the handful of key data annotation tools that our team often discusses with leaders from Data Operations and Machine Learning teams (as well as radiologists, clinicians, and the broader annotation community) as they are getting started in their ‘data annotation’ journey. Viewing and annotating medical data, images, and videos is a crucial, and frequent, task for many practitioners in the healthcare industry.Ī starting point for many when evaluating how to go about this task, will be to start with open-source medical imaging annotation tools – these tools are a popular choice in the medical sector and can be a smart way to save money when getting started on an image or video dataset annotation project.
