Available in PDF, EPUB and Kindle. Book excerpt: When the United States Air Force completed a multi-million dollar transition to digital dental radiography in 2010 there was no quantitative method available for establishing the appropriate balance of image quality and radiation dose. The objective of this research was to devise a process to fill this need. Through computer simulation and clinical validation the effect of technical parameters on digital dental radiographic image quality was investigated and an optimization method was devised. The Monte Carlo N-Particle Extended (MCNPX) radiation transport code was used to model the DC Planmeca Intra and AC Gendex 770 dental intraoral radiographic units and a unique anthropomorphic phantom simulating dental bitewing anatomy. The Carestream 6100 RVG sensor signal response, noise response, dose rate dependence and reproducibility were determined experimentally, as were their uncertainties and the inter- and intra- radiographic unit variabilities. The experimental measurements were used to calibrate and scale the MCNPX generated data for the optimization analysis. The technical parameters modified in the simulation were peak kilovoltage, (50 through 90) and tube filtration (inherent, 0.1 mm and 0.2 mm added copper). The entrance air KERMA (~720 microGy) at the current clinical technique (63 kVp at 1 milliAmpere-seconds) was used to establish the reference image quality metrics for comparison. Four figures of merit (FOM) were chosen to encompass the impact of variations in the adjustable parameters. With equal weighting of all FOMs and given no limitations on the equipment, the optimal combination of kVp and tube filtration for dental bitewing imaging identified was 90 kVp with 0.1 mm added copper filtration. The optimal technique in the radiographic units' operating range was 70 kVp and 0.1 mm added copper filtration, which could be immediately adopted for a ~50% (+/-17%) entrance dose and ~40% effective dose savings (Planmeca units). In general, the optimization method facilitates image quality standardization across different radiographic units and sensors in a dental clinic. The unique computer model and optimization method used could be easily customized to evaluate any adult or pediatric intraoral imaging task. The results underscore the importance of tailoring the technical parameters to the particular imaging devices in service.

Download or read book Optimizing of Dose and Imaging Quality for Computer and Digital Radhiography written by Zubir Ahmad Shazli and published by IIUM PRESS. This book was released on 2021-04-01 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimization of dose in radiographic examinations is essential since the utilization of x-radiation is related to increased cancer risk. The study’s objective was to guide radiographers in ensuring best practices for common radiographic examinations of acceptable image quality in digital radiography while minimizing radiation doses that could result in harmful effects. The study comprised of three phases. The first phase involved 90 respondents between 20 to 60 years of age and weighing between 60-80 kilograms for the following examinations: anterior-posterior (AP) abdomen, AP or lateral lumbar sacral spine and posterior-anterior (PA) chest examinations. During this phase, the radiographic examination’s technical parameters for 30 radiographs for each examination were at the radiographers’ discretion. Kerma X_plus, DAP (dose area product) meter was utilized to evaluate the entrance surface dose (ESD), while CALDose_X 5.0 Monte Carlo was used to estimate the effective dose. The experimental study utilized an anthropomorphic phantom (PBU-50) and Leeds test object to compare the image quality. The best parameters were adapted to the patient’s AP thickness for the optimization study from the different technical parameters used in the experimental phase.

Download or read book An Overview of Dental Image Processing Techniques written by G. Jaffino and published by Shanlax Publications. This book was released on 2024-06-28 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dental image processing for person identification focuses on using digital dental X-rays or photographs to establish a person's identity. Each person has a unique dental "signature" defined by the number of teeth, their position, shape, size, and any dental work like fillings, crowns, or implants. Similar to general dental processing, initial steps involve noise reduction and image enhancement for better analysis. Extracted features are compared to a database of dental records, which could be antemortem (pre-mortem) X-rays of a missing person or postmortem X-rays of unidentified remains. Matching algorithms analyze the similarity between features. While not a foolproof method, dental image processing can provide strong evidence for identification, especially when combined with other forensic techniques like DNA analysis. Overall, dental image processing offers a promising tool for forensic identification, particularly when used alongside other methods.
