What is automatic exposure control in mammography?

What is automatic exposure control in mammography?

Automatic exposure control (AEC) is a device incorporated into radiographic and mammographic imaging systems. Its function is to automatically terminate exposure when a preset amount of radiation has been detected.

What is the purpose of automatic exposure control AEC in radiography?

AEC is a radiographic density control device that terminates the exposure when a predetermined amount of radiation has been reached. Newer systems control kVp and mA as well as exposure time.

What is Mee in mammography?

MQSA Requirements for the Mammography Equipment Evaluations (MEE) (see Attachment A) Mammography equipment evaluations must also be performed whenever equipment is disassembled and then reassembled at the same or a new location or whenever a major component is changed or repaired.

What is the purpose of a technique chart?

A technique chart provides a consistent method of choosing the proper radiograph settings without having to calculate all of the components by hand with each exposure. Taking the time to prepare a technique chart in the beginning will help to save time, money, and radiation exposure to both the patient and staff.

Why do we use AEC?

The intention of AEC is to provide consistent x-ray image exposure, whether to film, a digital detector or a CT scanner. AEC systems may also automatically set exposure factors such as the X-ray tube current and voltage in a CT.

Why AEC is significant in mammography?

Automatic exposure control (AEC) is an important feature in mammography. It enables consistently optimal image exposure despite variations in tissue density and thickness, and user skill level.

What is MQSA certified?

Certified Facilities/Certificates Certification means that a mammography facility has been MQSA certified and is capable of providing quality mammography.

How long is ACR accreditation good for?

In response to increasing limitations and restrictions of physicist access to imaging facilities due to the COVID-19 outbreak, the ACR will extend the annual medical physicist equipment survey accreditation requirement to a 16-month window from date of last equipment evaluation.

What are the regulations for mammography in the US?

The regulations set forth in this part implement the Mammography Quality Standards Act (MQSA) (42 U.S.C. 263b).

What does FDA mean by accreditation body in mammography?

The following definitions apply to subparts A, B, and C of this part: (a) Accreditation body or body means an entity that has been approved by FDA under Sec. 900.3 (d) to accredit mammography facilities.

How to become an accredited body for mammography?

Subpart A of this part establishes procedures whereby an entity can apply to become a Food and Drug Administration (FDA)-approved accreditation body to accredit facilities to be eligible to perform screening or diagnostic mammography services.

When does a supervisor need to be present for a mammography exam?

(2) During the performance of a mammography examination or survey of the facility’s equipment and quality assurance program, the supervisor is present to observe and correct, as needed, the performance of the individual being supervised who is performing the examination or conducting the survey.
