A recent study conducted by John Ludlow, DDS, of the University of North Carolina School of Dentistry confirmed that Carestream Dental’s CS 9300 family of cone beam computed tomography (CBCT) systems can provide 3D exams at up to an 85% lower dose than traditional 2D panoramic imaging. The 3D images captured using the low-dose mode for a 5 x 5 cm, adult exam provides an effective dose of just 3 microsieverts (µSv).

Dose-saving algorithms and noise reduction processing enable the new, low-dose mode to significantly lower the dose and scanning time of the CS 9300—between 73% and 95%, as compared to standard acquisition mode2—while maintaining diagnostic image quality. The low-dose mode is available for 17 x 11 cm down to 5 x 5 cm scans, and it covers multiple applications, including implant planning; conducting follow-up exams for orthognathic, maxillofacial surgery, or implant; analyzing skeletal symmetry; assessing airways; evaluating impacted teeth and supernumeraries; and performing pediatric examinations.

“We all naturally absorb about 2,400 µSv of radiation per year from our surroundings,” remarked Ed Shellard, DMD, chief commercial officer of Carestream Dental, Atlanta. “Low dose can optimize the dosage to just 3 µSv for a 5 x 5 cm adult exam, or less than half a day’s equivalent background radiation. This is ideal for pediatric or follow-up examinations, which allows the practitioner to prescribe the image quality required while adhering even more to the ALARA [As Low as Reasonably Achievable] Principle.”

An additional benefit of the new low-dose mode is that existing units in the CS 9300 family can easily be retrofitted with the module so that doctors can treat patients with the lowest dosage possible.

Along with reduced radiation, the CS 9300 offers 3D imaging technology and 2D digital panoramic imaging with variable focal trough technology. One-shot cephalometric imaging is available as an optional feature. The system produces an image resolution of up to 90 µm with 1:1 accuracy and features medium- to large-field 3D imaging with seven selectable fields of view, ranging from 5 cm x 5 cm to 17 cm x 13.5 cm. These fields of view support a wide variety of clinical applications, including implantology, oral and maxillofacial surgery, orthognathics, and orthodontics.

The CS 9300 family also includes the CS 9300 Select, which offers medium field 3D imaging with four fields of view. The CS 9300 Select is also available with an optional cephalometric arm and can be upgraded with the low-dose module.
