About This Seminar
Due to past incidents involving patient overexposure, a great deal of
publicity and attention has been put on the protocols and dose used
in computed tomography. Medical physicists have a critical role to
play in helping facilities control radiation dose and improve CT
protocols to provide valuable clinical information while minimizing
risk. The appropriate role of the medical physicist in these
activities will be emphasized. The requirement for facilities to
accredit their CT units is growing. This is posing a challenge to
medical physicists to increase their knowledge of this technology and
the accreditation procedures for CT units. This seminar will provide
an interactive forum with time for discussion of important aspects of
CT scanner operation, testing and QC. Participants are invited to
bring their questions and concerns about supporting these units for
an exchange with other attendees and the faculty. This seminar will
provide 15 hours of continuing education credit as required by the
ACR for qualified medical physicists supporting accredited
facilities.

Educational Objectives
At the completion of this
seminar attendees will:
- Understand the technology of multi-slice/multi-detector CT units.
- Learn how radiation dose from CT units is measured and controlled.
- Understand the development and optimization of CT protocols.
- Be familiar with the impact of reconstruction algorithms for various clinical applications.
- Be able to design an effective QC program for technologists and the physicist.
- Understand the requirements, testing required and proper submission of accreditation applications.
- Be familiar with various special applications and future directions
of CT.
