Tomosynthesis for Dental Imaging

Our image processing and algorithm development expertise helped fill a capability gap with a customer and led to the release of a new cutting edge tomosynthesis application for dental imaging.

Business Need

Create a cutting edge Tomosynthesis based dental imaging application for a mid-range Dental equipment player.
Suppress overlapping structures that make analysis of front tooth difficult in a Dental Panorama.
Cervical spine in Dental Panorama needs be to be removed
Reduced exposure to X-Rays as Tomosynthesis is a limited ROI reconstruction technique. This makes it especially useful in periodic post-operative diagnosis.

Background/ Context
QuEST’s expertise in medical image processing, algorithm development came in handy since customer did not have an R&D team for algorithm development.


Imaging Algorithm experts visited client site to understand the requirements and to understand the actual system
Prepared a generic algorithm for intra–oral and extra-oral Tomosynthesis
Algorithm experts worked closely with customer to optimize the algorithm for image re-construction and improve performance
Image viewing capabilities of the existing system was improved to incorporate the new workflow


Customer R&D effort is reduced considerably and customer need not pay any royalties for research institutions
Early bird advantage and sales pitch for using Tomosynthesis among dental imaging fraternity
