Program Summary

The use of CT has rapidly increased in recent years leading to substantial concern regarding medical imaging-related radiation dose. An important strategy to decrease patient dose while maintaining image quality is the use of iterative reconstruction (IR) algorithms. These algorithms have the advantage of reducing image noise, improving the contrast to noise ratio and increasing subjective image quality of CT studies. Initial hybrid IR approaches have been increasingly superseded by model-based iterative reconstruction techniques that use precise system statistics and optics models to further reduce image noise. One such algorithm, iterative model reconstruction (IMR) is the focus of this presentation.

The presenters will discuss an intuitive approach to understanding the physics behind IMR and its capabilities with respect to reducing imaging noise leading to both an objective and subjective improvement in image quality on CT. Relevant literature on this topic will be reviewed. Finally, the presenters will show examples acquired from various parts of the body to demonstrate the benefits of IMR use in comparison to conventional imaging and hybrid IR techniques.

Following their presentations questions from the audience were addressed in a moderated Q&A session.

Learning Objective

Upon completion of this CME activity the healthcare provider should be able to:

1. Explain using an intuitive approach, the physics related to current model based reconstruction approaches on CT.
2. Compare current model based reconstruction approaches to earlier algorithms, showing how they can lead to an improved image quality.
3. Demonstrate examples from various parts of the body that indicate an advantage for images reconstructed with current model based reconstruction approaches

No special educational preparation is required for this CME/CE Activity!
