About This Seminar
The involvement of medical physicists in ultrasound imaging services
is increasing at many facilities as they seek the accreditation to
qualify for reimbursement by some insurance companies. The American
College of Radiology (ACR) requires a medical physicist to
oversee a quality assurance program in facilities seeking
their accreditation. Medical physicists supporting these facilities
need to update their skills as well as meet the continuing education
requirements of various accrediting bodies. This workshop is
designed to meet those needs and provide 15 hours of continuing
education credits. An indepth review of ultrasound technology will
be given along with an opportunity for hands-on application of
quality assurance testing procedures. The workshop will be conducted
by a well qualified faculty including two medical physicists in
private practice. Wayne Hedrick is co-author of a book entitled
“Ultrasound Physics and Instrumentation” and Terry Zipper is a
physics member of the ACR Advisory Committee on Ultrasound
Accreditation. The faculty also includes Mary Henne, a practicing
sonographer experienced in teaching ultrasound physics.

Educational Objectives
At the completion of this program, participants will:
- Have reviewed the basic physical concepts of ultrasound.
- Have learned the properties and instrumentation of real time ultrasound transducers.
- Recognize artifacts in ultrasound images.
- Understand the principles and applications of Doppler ultrasound.
- Be able to design and implement an effective QA program for clinical ultrasound services.
- Have reviewed requirements for ultrasound facility accreditation.

Workshop Format
|
|
The workshop will include material presented in lecture format
with PowerPoint slides and video illustrations as well as a
group demonstration of scanning a live model. Hands on
laboratory sessions of QA testing procedures using various
phantoms will provide opportunities to apply the testing
procedures under the guidance of an knowledgeable and
experienced faculty.

Workshop Credit
|
|
Approval has been received from CAMPEP for up to 15 hours of
Medical Physics Continuing Education Credit (MPCEC) for
qualified medical physicists. A certificate documenting
attendance will be provided to all participants.
