Weird, I don't see that happening on my iPhone though

For example, with this image, in any example that I do the test, the same thing happens to me on iOS

Have you shared the data with us?

Could you kindly provide the data if it has been anonymized and you can confirm that there is no patient health information present in any of the headers or embedded within the pixel data?

Try with cornersotnte3d 2.0 it is fixed

Cornerstone3D 2.0 has been released. It comes with:

  • New Segmentation Architecture: Segmentations are now treated as first-class data structures, not just tools. This allows for greater flexibility and support for advanced visualization, such as multi-representational views, viewport-specific customizations, and easier management within MPR layouts.

  • Introduction of VoxelManager: A more memory-efficient and streamlined approach to voxel data handling, replacing traditional scalar arrays with a unified, image-based system. This change reduces memory usage, enhances data clarity, and simplifies data access across stacks and volumes.

For more details on these updates and to guide you through the migration, please refer to our Migration Guide.
