DICOM Modality Explained

The type of equipment or imaging method that produces the images
Alert
Why does the correct Dicom Modality matter? 
Correct image type = correct workflow
If an image is saved under the wrong modality, it might not show up in the right place in their software. For example, a CT scan accidentally saved as a normal X-ray could cause confusion or delays.
Smooth integration with other systems
Practices often send images to specialists, labs, or hospitals. The receiving system relies on the modality tag to know what kind of image it’s getting. Wrong modality = problems sharing or viewing.
Compliance and patient safety
Properly labelled images reduce the risk of clinical mistakes. Staff can be confident they’re looking at the right type of scan for the right patient.
Troubleshooting made easier
If something isn’t displaying properly, one of the first checks is whether the modality is set correctly. If staff understand the basics, they can spot issues quicker before escalating.
IO – Intraoral X-Ray
  1. X-Ray sensors (MediaRay Plus, Kodak RVG, Sirona XIOS XG etc.) and Phosphorus plate scanners (MediaScan, Digora Optime, Kodak CS7600/CS7200 etc.)
  2. Default of all intra oral X-Rays
CR - Computed Radiography
  1. Only Phosphorus plate scanners (MediaScan, Digora Optime, Kodak CS7600/CS7200 etc.)
  2. Setup only if specifically requested
ES - Endoscopy image
  1. Use only and exclusively for ALL intra oral cameras such as MediaCam Pro, MediaCam 2, Sopro, Mouthwatch etc 
PX – Panoramic
  1. Use for all OPG devices such Soredex Cranuss Novus, Planmeca ProMax, Vatech Pax -I etc
  2. Use only if confident this is the OPG (Panoramic device) or a COMBO one (CBCT+OPG)
DX – Digital radiology
  1. Can be used only in case there is no information on the device except it is a digital X-Ray machine
XC – Digital Photographic image
  1. Cannot be setup for automated apply
  2. It should be manually entered on each image import in the Examination page
OT – Others
  1. The default modality for the import.
  2. Used when it is not possible to identify the correct one

To show the average density of the area within the shape, in Hounsfield units (HU):
  1. This density measurement is only accurate for CT images where they are recorded in DICOM format
  2. 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.
