This study, conducted at the University of Salford, explored the effects of body part thickness on image quality (IQ) and effective dose (E) during pelvis radiography, using an anthropomorphic pelvis phantom with added layers of animal fat to simulate increasing body thickness.
The research aimed to identify optimal exposure parameters for patients of varying sizes. Using automatic exposure control and varying tube potentials (70-110 kVp), the study found that as body thickness increased, the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) decreased, particularly at lower kVp settings. However, lower kVp (70-75 kVp) consistently yielded the highest IQ scores, challenging the common radiographic practice of increasing kVp with patient size.
The study concluded that lower kVp settings are most effective across a range of thicknesses, advocating for reconsideration of current practices to optimise radiation dose and image quality in larger patients.
This research is significant for its implications in improving radiographic techniques for diverse patient sizes, ensuring both safety and diagnostic accuracy.
As a leading provider of pelvis phantoms, we are delighted to note the relevance of our products in this groundbreaking study conducted at the University of Salford.
The research underscores the importance of high-quality phantoms in evaluating and optimising radiographic techniques, particularly in managing variations in patient size. Our pelvis phantoms, which were integral to this study, have demonstrated their value in advancing radiographic practices and ensuring patient safety. The study aligns perfectly with our commitment to supporting the medical imaging community with superior and reliable phantoms, aiding in the development of safer, more effective imaging protocols.
We are proud to contribute to such significant advancements in radiographic imaging.
