Multi-Planar Annotations in V7

This feature allows annotations made in the axial plane to be seamlessly projected onto the sagittal and coronal planes, allowing more radiology use cases to be labeled in V7.

Key Benefits:

Comprehensive Insight: You can now annotate in the axial, sagittal, and coronal planes, enabling a thorough understanding of anatomical structures from multiple perspectives

Efficient Workflow: Editing annotations in all planes becomes effortless, streamlining the process and minimizing errors

How to Create Multi-Planar Annotations in V7

To use our Multi-Planar Annotation functionality you must have:

1. A DICOM or NIfTI file that has been extracted into the axial, sagittal, and coronal planes
2. A Mask class created for this dataset

After this - you are free to start creating Masks using the Brush Tool or Polygon Tool in any of the 3 planes, and you will see the annotations projected into the other views.

Introducing the 3D Thresholding Brush Tool

The 3D brush tool is a game-changer in multi-dimensional annotation, designed to make labeling across slices not just possible but significantly more efficient. Here's how it elevates the annotation experience:

• Compatibility: Specifically developed for mask annotations, this tool allows you to create and edit masks across any of the axial, sagittal, and coronal views.
• Versatile Shapes: Start with a 3D sphere or cube shape, with symmetry in dimensions (e.g., 5 pixels wide x 5 pixels deep for cubes, or a 5 pixels diameter for spheres). These are merely the initial brush shapes; your final annotation can adopt any form.
• Customizable Size: Adjust the brush size to your needs using the toolbar's +/- buttons or the [ and ] hotkeys.
• Easy Toggle: Switch between 2D and 3D brushes with a toolbar click or the ctrl-R hotkey.
• Apply Thresholding: Find a good window/level to label pixels based on their intensities. Switch between standard and thresholding brush with the hotkey ctrl-T.

Tips and Tricks

The multi-planar annotation feature is most beneficial when it is used in parallel with the Crosshairs Tool and the Zoom Tool
