WE-A-TRACK 7-0 (Wednesday, 7/28/2021) 10:30 AM - 11:30 AM [Eastern Time (GMT-4)]

The workshop will include five presentations covering a range of current topics in diagnostic ultrasound QA/QC. “Annual Survey” requirements will be presented, outlining steps and pitfalls of ACR-required ultrasound system tests. These include image uniformity and artifact surveys, geometric accuracy and system sensitivity tests, and display monitor evaluations. QC phantoms will be described for testing general purpose ultrasound scanners. This will be followed by descriptions of specialized phantoms and procedures for performance assessment of automated whole-breast screening ultrasound units. In addition, an overview of Doppler system testing using flow phantoms will be provided. Efforts to assess shear wave elastography and an initiative to estimate “pulse-echo quantitative ultrasound” parameters, including attenuation and backscatter coefficients and speed of sound, by the Quantitative Imaging Biomarkers Alliance (QIBA) and the American Institute of Ultrasound in Medicine (AIUM), will be introduced. Lastly, innovative software programs for automated QC will be described.

The targeted attendees are medical physicists and other medical professionals in diagnostic imaging and radiation oncology with interest in diagnostic ultrasound QC.

Learning Objectives:
1. To gain familiarity with common elements of a QA/QC program for diagnostic ultrasound scanners, including automated whole-breast screening ultrasound systems. QC tools, phantoms and automated software programs will be described.
2. To provide an overview of important phantom characteristics for evaluating Doppler ultrasound equipment and to outline Doppler system tests that can be performed using flow phantoms.
3. To introduce the AIUM/QIBA efforts in assessing shear wave elastography and the emerging pulse-echo quantitative ultrasound features.
