Capture low dose CBCT images without movement artefacts

Blog post   •   Jul 19, 2018 07:26 GMT

All Planmeca CBCT units support three different types of 3D imaging as well as extraoral bitewing, cephalometric and digital panoramic imaging. This flexibility between 2D and 3D allows clinics to optimise their imaging and select the techniques that work best with each case. With proprietary features for ultra low dose imaging and patient movement correction also available, our units provide a completely unique dental imaging experience.

Planmeca Ultra Low Dose™ is the best method for acquiring CBCT images at low doses. The protocol can be used with all voxel sizes and in all imaging modes and allows clinicians to gather more information than from standard 2D panoramic images at an equivalent or even lower dose. All this is possible without a statistical reduction in image quality*.

Whereas Planmeca Ultra Low Dose protects patients from unnecessarily high doses, the new Planmeca CALM™ imaging protocol helps avoid retakes by compensating for movement. 

According to studies**, patient movement can occur in up to 40% of cases, meaning that image quality is not optimal in a significant portion of CBCT scans. Planmeca CALM corrects artefacts caused by movement, resulting in sharper final images. The algorithm can be applied after a scan is complete, but also already before the exposure.

When purchasing a new CBCT unit, be sure to exercise your right to receive all valid information on a product. Always ask for accurate info on patient doses and compare the differences in image quality between standard and low dose images, as well as images with and without artefact correction. The right choice will lead to improved diagnostics, saved time, reduced costs and lower patient doses.
