7:30 AM : Performance Evaluation of Ultrasound Systems: Advanced Methods and Applications - N Hangiandreou, Presenting AuthorWE-A-708-0 (Wednesday, August 2, 2017) 7:30 AM - 8:25 AM Room: 708
Traditional approaches to measuring ultrasound system performance have been previously described and demonstrated. Although suitable for many applications, there remains a need for a comprehensive set of tests to predict the clinical performance of ultrasound systems in an objective manner, as evidenced by a recent letter from the chair of the AIUM Technical Standards Committee soliciting interest in development of such a test suite. A set of tests such as this could be used for a wide variety of applications including pre-purchase imaging system assessments, comparing performance for specific clinical applications across a range of technology levels and costs, and for optimization of the imaging performance of clinical imaging systems. This talk will discuss advanced methods of ultrasound performance assessment that might contribute to the goals stated above. Advanced approaches discussed will include commercial analysis tools for objectively assessing basic performance metrics, assessment methods based on detection or depiction of clinically-relevant targets, and approaches for improved assessment of Doppler functionality. Also an overview of shear wave elastography imaging techniques will be presented, along with initial approaches for assessing the quality of these images. In addition, the use of materials to cause image distortions to existing phantoms will be described as one attempt to make these performance measurements more relevant to clinical patient scanning. The talk will conclude with some cases studies of performance assessments performed recently in our clinical practice, describing the use of some of the testing methods discussed above.
