To show the average density of the area within the shape, in Hounsfield units (HU):
- This density measurement is only accurate for CT images where they are recorded in DICOM format
- Intraoral X-rays, OPGs etc. don't have the same density data as CT/CBCT (they’re just 2D images with pixel brightness/contrast), as such, these measurement tools can still be used to highlight or mark up images, but the “density” values shown are not reliable for diagnosis.
- Select the tool
