Filter and Hide Labels

Choose the filter option in the Labels Controls and select the labels and label group you would like to filter by. Then click filter again. When you open the Exam window in the Navigation column, you'll see only the filtered cases.

Types of filters

  • AND filter will show only the exams that contain all the labels you have selected.
  • OR filter will show the exams that contain any of the labels you have selected.
  • NOT filter will show only the exams that do not contain the labels you have selected.

Remove labels in bulk

BULK REMOVE is a feature to remove specific label annotations from the exam, series, or image level. It's useful if you've added many labels with the interpolation tool that you need to delete and reannotate.

Hide labels

Hide works similarly. Choose the hide option in Label Controls and select the labels you would like to hide. You can also hide individual annotations on an image by using the hide icon on the annotation tag.

Administrative label control features

  • Label order can be changed using the REORDER Labels selection
  • Edit or delete labels with the corresponding selection in LABEL CONTROLS
The third column is navigation. If you touch any of the light blue boxes you’ll see a list of exams, series, or images.
