About annotations, retinal drawings and measurements
Annotations are graphical mark-ups drawn onto the image. Standard annotations are available for all
image types.
Retinal drawings and measurements are special annotations. Retinal drawings are used to indicate
specific information, for example arteries, detached retinas and exudates. Measurements calculate
distance and area parameters on the image. The calculated results are added to the image as
annotations. Some special annotations are restricted depending on the type of image being reviewed.
You can use annotations to highlight areas of special interest on an image. The annotations are saved
with the image and can be sent to another person to be reviewed. Several reviewers can add annotations
to an image. You can view all of the annotations, or decide which annotations you want to view and hide
the others.
Annotations are saved when the image is closed.
Note
l
Annotations and retinal drawings cannot be edited or deleted after the image has been closed.
l
Retinal drawings are not available on standard optomap® images.
l
If you export or email the image using the Medical Image Format (*.dcm, DICOM file) the mark-
ups can be viewed by other medical image applications. Using DICOM format allows for the
areas under the mark-ups to be reviewed.
l
If you export or email the image using any format other that the Medical Image Format (*.dcm,
DICOM file) the mark-ups will 'burned-in' the image and the area below the mark-up lines will be
obscured.
