April 2024 Cycle Report
8 April 2024 by Miriam Groeneveld and Chris van Run
This cycle, the RSE team has extended the usability around images with a time component. Where before, you only had the option to select different time frames, you can now play as if the image was a video. You can set playback to once or continous, have the video loop or play in ping-pong style, and you can set the playback speed. For 3D images, we have added a configuration option that allows you to set the initial slice on which an image should be shown. A configuration option in your profile now supports instant email notifications, which is useful when you want to be notified of failed image uploads or other issues instantly, rather than once a day. We also further extended the support for annotating images in our client-side pathology viewer.
March 2024 Cycle Report
4 March 2024 by Miriam Groeneveld
The end of the March Cycle will bring you some shiny new features in both Grand Challenge and our viewer. In Reader Studies, you can now send direct messages to your readers. We added an option to Reader Study questions that allows you to verify that a user intentionally left an answer blank. We added support for viewing PDF and Vega Lite charts in dedicated view items, giving you full control over the data displayed in your Reader Stusy, Archive or Algorithm results. We also extended the support for Three-point angle annotations, added to Reader Studies last cycle, to be used in Archives and Algorithm results. Read the blog for more details!
January 2024 Cycle Report
29 Jan. 2024 by Miriam Groeneveld
The RSE team started the year with exciting updates! We've shifted algorithm job and challenge evaluation execution to Amazon SageMaker Training, removing one-hour time limits for algorithms. Editing and creating display sets is now easier, reducing reliance on our API. Cirrus now supports seamless display of videos, thumbnails, and text alongside medical images. We've improved 3D image display, eliminating the need to navigate after changing orientation. In educational reader studies, we introduced an "Instant Verification" option for faster participation. Users can now set default colors for reader study questions. Check out our blog for more details on these enhancements!

October 2023 Cycle Report
16 Oct. 2023 by Miriam Groeneveld, Paul K. Gerke, Chris van Run, James Meakin and Harm van Zeeland
In this cycle, we worked on improving the performance of our reader studies, enabled setting the viewing depth of annotations in 3D images, and continued our work on the client-side pathology viewer. One of our team members attended Miccai 2023 to meet with challenge organizers and receive feedback. Read the blog for more details!
September 2023 Cycle Report
12 Sept. 2023 by Miriam Groeneveld, Chris van Run, Paul K. Gerke and Harm van Zeeland
This cycle, the RSE team dedicated significant efforts to support various MICCAI 2023 challenges. Additionally, we enhanced the Cirrus viewer's usability, enabling seamless switching between different hanging protocols within the viewer. Furthermore, we addressed a prior issue, reinstating the functionality to switch between the polygon and mask editor. In the context of mask creation, we introduced a new feature allowing you to conveniently hide the annotation you're editing for accuracy verification using a straightforward keybinding. Explore our latest blog post for more details!
August 2023 Cycle Report
10 Aug. 2023 by Miriam Groeneveld, Paul K. Gerke and Chris van Run
This cycle the RSE team has started working on a new, experimental feature: Implementing a client-side viewer, for now specifically for pathology images. This should provide a faster, more responsive experience when viewing these images. Furthermore, the GitHub repository integration has been improved and bugs squashed. Challenge organizers can now combine results from different phases to create an overall leaderboard. Finally, we have added support for viewing overlapping semantic segmentations.
July 2023 Cycle Report
13 July 2023 by Miriam Groeneveld and James Meakin
This cycle we have brought some new additions to the reader study questions, check it out!
May 2023 Cycle Report
30 May 2023 by Miriam Groeneveld
This cycle, the RSE team has made improvements for pathology. It is now possible to upload DICOM-WSI files, they will be converted to tiff. Segmentations as tiff files are now supported and will be validated according to the segmentation interface. The annotation statistics plugin has had an overall make-over, with progress bar and caching improving general usability. Other features include a 3D brush for creating and editing masks, and improvements to the admin page for challenge organizers.
April 2023 Cycle Report
26 April 2023 by Chris van Run, Paul K. Gerke and Miriam Groeneveld
Cycle report of the research-software engineers of April 2023, including constrained number inputs, browser-native history support when context switching, and editing annotation metadata
March 2023 Cycle Report
20 March 2023 by Chris van Run and Miriam Groeneveld
Cycle report of the research-software engineers of March 2023, including: more statistics on Grand Challenge, updated algorithm-job permissions on Grand Challenge, upgrade the CIRRUS backbone MeVisLab version to v3.6, added a new reader-study workflow for accepting and rejecting findings in both CIRRUS and Grand Challenge.
January 2023 Cycle Report
15 Feb. 2023 by Miriam Groeneveld
This cycle work was done to make algorithm result viewing faster by reusing Cirrus sessions. We also made it possible to select existing images for trying out an Algorithm, creating a Display Set in Reader Studies and creating Archive Items.
December 2022 Cycle Report
10 Jan. 2023 by Miriam Groeneveld and Chris van Run
In this year's first release, we added the option to reuse existing images to run an algorithm on or create an archive item or display set. Previously this was only possible with the python client. We extended our annotation types with the ellipse annotation, to be used in Reader studies or Algorithms. Under the hood, we are working on improving the viewing of pathology images, making them faster and more error-proof. To improve the reliability and ease of use of the GC-API client, we have added retries to certain requests in the client. This should reduce the number of errors that need to be handled by the user.

How to build a global, scalable, low-latency, and secure machine learning medical imaging analysis platform on AWS
24 Aug. 2020 by Razvan Ionasec, Bram van Ginneken and James Meakin
It is hard to imagine the future for medical imaging without machine learning (ML) as its central innovation engine. Countless researchers, developers, start-ups, and larger enterprises are engaged in building, training, and deploying machine learning solutions for medical imaging that are posed to transform today’s medical workflows and the future value of imaging in diagnosis and treatment.
