INTERACTIVE ANNOTATIONS

ONIS has the most advanced annotation system. Like many other DICOM viewers, you can create measures, angles, rectangles, circles, polygons and text annotations. But ONIS brings you an innovative concept: annotations that can interact which each other. Intersection points between different and independant annotations can be used to create new measures!

Intersection points between annotations define new segments that can be use for a measure or for creating a perpendicular or a parallel line. Consecutive segments can be merged together for measurement. Combining the tools together, you can create virtually any kind of measures, from the simpliest to the most complex.

Last but not least, all annotations are dynamic. When you move one annotation, the intersection points with other annotations are also adjusted, and any measures recalculate accordingly.

 

 


ONIS has several tools to measure areas. You may use a rectangle, an ellipse, a polygon or a pen. To improve accuracy, ONIS supports pixel brightness thresholds (minimum and maximum) that work only in the target area. To aid in visualizing the calculated area, a semi-transparent coloured layer will appear over the area, highlighting only the pixels taken into account.

Statistics such as areas, means or standard deviations have never been so easy to determine!

 

 


With ONIS, you can create the following annotations:

  1. Measure

  2. Angle

  3. Line

  4. Polyline

  5. Rectangle

  6. Ellipse

  7. Polygon

  8. Pen

  9. Arrow

  10. Text


On consecutive segments, you can do one or more of the following actions:

  1. Measure length

  2. Measure angle

  3. Measure ratio

  4. Split

  5. One side orthogonal

  6. Two side orthogonal

  7. Parallel


You also can flip horizontally and vertically the annotations.
