Why is DDI imaging exceptional?

The Staff

  • Oral and Maxillofacial Radiologists (OMR).  An OMR is a dentist with additional advanced specialty training in radiology of the teeth and jaws.  
  • Dental radiographic technologists (DRT). A DRT is a x-ray technologist educated specifically in dental radiography to perform dental-maxillofacial imaging procedures.
  • Support staff that have years of knowledgeable and compassionate care that work with patients to ensure your experience goes well.  

The Equipment

  • The first imaging center in the United States to implement the use of Cone Beam Computed Tomography (CBCT) for dentistry.
  • DDI uses high quality scanners. Not all dental CT scanners are equal.
  • Regularly upgrades to the next generation machine for improved image quality and reduced radiation dose.  


  • CBCT machines are highly tuned and maintained to provide excellent, consistent image quality.
  • Daily quality control testing, phantom testing and geometric calibration analysis is performed routinely.
  • CBCT quality assurance testing ensures consistent and optimized image quality.  


  • Image data is collected from the CBCT scans.
  • Multiple software platforms as needed generate diagnostic image sets.  
  • Customized series of images is created for each patient and made available with the referring doctor for diagnosis and treatment.

Scan Protocol

  • Quality CBCT acquisition is critical to obtaining an accurate representation of anatomic pathosis.
  • Specific scan protocols are designed to meet the imaging objectives of each patient.
  • Scan protocols are instrument and patient specific as this provides the best possible results with the lowest dose to answer the diagnostic question.
