OWN THE FUTURE Practice Ultra Low Dose 3D imaging with lower dose than panoramic imaging
Ultra Low Dose Pioneering low dose 3D imaging 3D units offer a unique Ultra Low Dose imaging protocol that enables CBCT imaging with an even lower patient radiation dose than standard 2D panoramic imaging. This intelligent protocol can be used with all voxel sizes and in all imaging modes from Normal to Endodontic. Using the Ultra Low Dose protocol reduces the effective patient dose by 75 80%. Ultra low dose images are ideal for many clinical cases, such as: Orthodontics: - Defining the amount of bone around the root - Localizing unerupted and impacted teeth before orthodontic treatment - Defining orthodontic landmarks for cephalometric analysis Post-operative and follow-up images in maxillofacial surgery Airway studies Sinus studies Implant planning

Doctor testimonial Ultra Low Dose protocol has changed imaging practices at Tampere University Hospital in Finland Dr Jorma Järnstedt, DDS, Specialist in Oral and Maxillofacial Radiology, Department of Radiology, Medical Imaging Centre, Tampere University Hospital, Finland We have been using the new Ultra Low Dose protocol since summer 2013, and we have found it to be very useful in many imaging indications. These include postoperative follow-up, orthodontic cases requiring localization of impacted teeth and their effects on the neighbouring ones, detection of facial asymmetries, sinus imaging in certain ENT cases where sinusitis needs to be excluded, pharyngeal airway measurements in sleep apnea patients, as well as many implant cases. The new imaging protocol has already changed traditional imaging practices: in many cases, 2D imaging can no longer be justified, since an ultra low dose 3D image simply gives so much additional information at a similar radiation dose.

Effective patient doses Background and methodology Effective doses of 3D units Juha Koivisto Ph.Lic. (Phys) Corporate Physicist The dose measurements are performed using an anthropomorphic RANDO phantom and MOSFET dosimeters positioned into the phantom, according to the effective dose measurement protocol described by Ludlow et al. The effective dose calculation is based on using the revised guidelines given by the International Commission on Radiological Protection (ICRP 103). At, the Corporate Physicist Juha Koivisto is in charge of the effective dose measurements.
