The ULD mode has proven to be an excellent way to lower patient doses while still maintaining high diagnostic value. Radiation protection guidelines vary in different parts of the world, but there is a global consensus, that a patient should not be exposed to unnecessary patient doses. According to the well-known ALARA (As Low As Reasonably Achievable) principle, imaging doses must be kept as low as reasonably achievable – patients must not be exposed to a higher dosage than needed to acquire images of sufficient diagnostic quality.
While it is always the clinician who decides the volume size and exposure values used, we can say that in general, it would be a good option to use the Planmeca ULD mode in the following cases:
- Postoperative and follow-up studies
- Localisation of unerupted teeth
- Ear, nose and throat (ENT) studies
- Implant planning
