About this Workshop
The technology of computed tomography has made significant strides
in the past few years, first with the development of spiral/helical
scanning and more recently with multi-slice (multi-detector row) CT
scanning capability. Clinical medical physicists have an important
role to play in supporting facilities seeking accreditation for this
new technology. This workshop will emphasize the ACR CT facility
accreditation process, testing procedures and the QA measurements
required. The University of Texas M.D. Anderson Cancer Center has
graciously allowed the use of several multi-slice CT units for this
training. These will include GE 64 slice, Siemens 64 slice and
Philips 64 slice CT units.
|
Educational Objectives
At the completion of this workshop, participants will have learned about:
- Techniques for measuring radiation dose for multi-slice CT units.
- ACR CT accreditation requirements/results.
- QA and artifacts in Multi-Slice CT.
- Shielding/siting issues for CT scanners.
