Simple image quality measures, such as standard deviation and contrast-to-noise ratio, which do not include the effects of properties such as image texture and signal power, can be misleading, particularly as they relate to radiation dose.

Quantifying performance on high resolution images, especially relative to a conventional resolution system generally displayed on a 512 image matrix, requires a careful understanding of image quality metrics. As with any major innovation, a physics-based performance evaluation is critical to understanding and optimizing the Precision’s ultra-high resolution modes in clinical use. The Aquilion Precision, making routine use of a ultra-high resolution detector, ultra-high resolution optics assembly, and ultra-high resolution 1024 matrix reconstruction, allows for visualization of fine detail to better delineate anatomical and pathological structures. The ability to provide more accurate diagnosis through improved image quality is at the heart of every advance in imaging technology. Today, the Aquilion Precision ultra-high resolution CT system is making the power of routine, ultra-high resolution imaging - within industry-standard DRLs - a reality. In addition, recent advances in detector and reconstruction technology have seen the radiation doses for a CT examination drop well below published industry-standard Dose Reference Levels (DRLs).

Each technological advancement has provided clinicians the ability to expand the role of CT in the diagnosis of a wide array of clinical presentations. Over the last thirty years, technological innovations have provided CT scanners with a continuous cycle of improvement to spatial and temporal resolution as well as overall faster scan times with wider anatomical coverage.
