Doppler Principles and Doppler Angle: The Truth About 60°
March 22, 2023 @ 7:00 pm - 8:00 pm EDT
ULTRASOUND SOLUTIONS CORP. is delighted to welcome Frank Miele, MSEE, President of Pegasus Lectures, Inc., for an enlightening discussion on the crucial importance of Doppler angle correction and how it relates to the accuracy of our results.
This lecture covers the basic principles of Doppler to make clear the role of the Doppler angle and the need for angle correction. Practical aspects of angle correction will be explained, including how proper angle correction should be performed. A brief historical look at why 60° was chosen as the standard, as well as identification of sources of error associated with angle correction will be addressed. Recent research which demonstrates the magnitude of errors associated with angle correction and the associated artifact of spectral broadening will be referenced. Everything will be presented using easy-to-understand straightforward language and clear illustrations to make this often misunderstood, but very important, topic comprehensible to all. (Approved for 1 SDMS CME credit provided one is present for the entire event)
Course Objectives: Upon completion of this educational activity, the participant will be able to:
• Identify the Doppler angle
• Express the angular dependence of Doppler data
• Recognize errors in Doppler angle specification
• Explain why data varies with Doppler angle used, even when correction is employed
• Specify which correction angles result in higher probability of less Doppler error
About Our Speaker:
Frank Miele, MSEE, founder and President of Pegasus Lectures, Inc., lectures nationally and internationally on ultrasound physics, hemodynamics, emerging technologies, and test-taking strategies. Frank has authored multiple texts, including Essentials of Ultrasound Physics: The Board Review Book and the newly published Ultrasound Physics & Instrumentation, 6th edition. Specializing in medical physics, Frank has produced multiple educational eCourses, authored Exam Simulation programs, as well as created the patented analysis algorithm method and apparatus for evaluating educational performance.
In addition to his teaching of students, Sonographers, Fellows, and Physicians, Frank is on the faculty of the Society for Vascular Ultrasound and currently serves as an advisor and trainer for Medical Imaging Ministries of America (MIMA), a non-profit organization bringing medical imaging capabilities to underserved countries and communities as recognized by the WHO.
This activity has been approved for 1.0 SDMS CME credit. The CME participant roster will be reported by Ultrasound Solutions Corp. to the SDMS CME Tracker System.
Important update from the SDMS:
SDMS no longer allowing its CME providers to issue Partial Credit for your participation in USC Ultrasound CME events. If you join late or leave early, the SDMS will no longer permit us to award partial pro-rated credit.
Therefore, from now on, in order to receive CME credit, you must be in attendance for the ENTIRE event via your own unique Zoom link that Zoom emailed to you when you registered. Then, and only then, will USC be able to award you any credit. So please be prompt and attentive to the time schedule. We apologize for any inconvenience, but again, this is a new SDMS policy we must abide by. Thank you for understanding.
