The quality control (QC) technologist is responsible for all quality assurance duties not assigned to the lead interpreting physician or the medical physicist. Normally, he or she is expected to perform these duties, but may also assign other qualified personnel or may train and qualify others to do some or all of the tests. When these duties are assigned to others, the QC technologist retains the responsibility to ensure they are performed in accordance with the regulations.
"Other personnel qualified" means persons with technical training appropriate for the task(s) assigned to them. Examples include a radiological technologist qualified under MQSA with appropriate training, a technologist who is trained to do the QC test(s) by the QC Technologist, or other persons appropriately trained to do the task(s) and supervised by the QC technologist. A receptionist or a secretary whose sole qualification is to copy documents, type, or answer the phone is not included under "other" qualified personnel.
