Beam Hardening Analysis Inspired by a Mathematical Model of a Human Visual System

SALIM M. AQIL, DDS, LCDR, DC, USN

FORMAT
One day a month a speaker discusses a dental topic during lunch. The sessions are informal and the group has an opportunity to interact with the speaker during the short discussion period at the end of the lecture. It requires only about one and one-half hour of your time to learn the latest developments in many areas of dentistry. It also offers the opportunity to become better acquainted with your colleagues and their staff since all dental allied personnel and technicians are also invited to attend.

OVERVIEW
High density objects such as metal or dental restorations can hinder image quality by introducing noise and beam hardening artifacts into the reconstructed image and compromise its diagnostic value. The new Planmeca ProMax 3-D Mid cone beam computed tomography unit with Romexis software has noise (Adaptive Intelligent Noise Optimiser, AINO filter) and artifact removal (low, mid, high) features that can be implemented to preserve image quality and thus diagnostic value. The quality of clinical images can be evaluated subjectively, but quantitative measures are also needed. This study was prompted by the availability of a human visual system-based mathematical model, based on the Weber-Fecher law and Michelson Contrast.

OBJECTIVES
• Discuss the principles of beam hardening and radiographic noise
• Basis of human-visual system based mathematical model
• Image analysis of radiographic artifact based on this mathematical model

PRESENTER
SALIM M. AQIL D.D.S., M.S. received his DDS degree from the University of California at Los Angeles in 2009. In 2010, he completed Advanced education in general dentistry at Naval Medical Center, San Diego. Upon completion, Dr Aqil practiced general dentistry in the United States Navy from 2010-2014. He then joined UT Health Science Center at San Antonio in the Department of Comprehensive Dentistry as a resident in Oral Maxillofacial Radiology and graduated in 2017. He is also practicing Oral Maxillofacial Radiology at Naval Hospital Bremerton in Washington.
