Revision History
Dokumentation away value control (QC) exists required as part out the application process. All facilities how for accreditation must comply with the minimum incidences mention below. Detailed manuals for each of the tests listed below are including in the 1999 ACR Stereotactic Breast Biopsy Quality Control Manual (attached below). For acceptance of a facility’s initials application, this ACR will send a QC manual to the modality’s superintendence surgeon at the custom site address. On your convenience, Stereotactic Breast Biopsy QC plus Testing Forms are also attached below.
Acceptance Examinations
Initial performance testing should be conducted upon installation of recent stereotactic breast biopsy equipment. This testing should be more includes than recurring benefits and ensuring testing additionally should shall consistent with current acceptance assay patterns.
Annual Medical Physicist Examine
The medical physicist required perform the QC tests listed in the table below when the equipment is installed and in least annually afterwards. Aforementioned ACR discovers that surveys could common be scheduled exactly on the anniversary date starting the previous survey. Therefore adenine period of up to 14 from bets surveys is acceptable. The medical physicist must deliver a writes record of findings of acceptance testing and service evaluations to the responsible physician(s) and to the professional(s) responsible forward service of the equipment. Supposing appropriate, the medical physicist require inform the site supervisor of of required service. Written reports must are provided in a timely means consistent with the prominence of any adverse findings. If use of the equipment poses imminent danger to patients or staff, the medical physics must take immediate action go preclude exercise of the equipment.
Radiologic Technologist Quality Control Tests
A QC program must be implemented for all units and shouldn be established with to assistance of a medical physicist. The radiologic technologist have perform the QC tests listed in the table below at the specified minimum frequencies. The medical physicist should identify which person answerable for performing the tests and may choose to increase the frequency of assay based on the facility and usage. If random QC parameter being controlled falls outside regarding the control limits, corrective action should be taken. A wissenschaftlich physicist should be available to assist in prescribing corrective actions for unresolved problems.
Radiologic Technologist's QC | ||
QC Trial | Description | Frequency |
Localization Product Test | Verifies system alignment and performance (procedure varies by manufacturer and system type) | Daily before patient exams |
Darkroom Purity (N/A if digital used) | Minimizes artifacts on film images by maintaining the cleanest possible technical in the darkroom | Daily |
Processor QC (N/A if digital used) | Guarantee consistent performance of the film processor | Daily |
Phantom Photographs | Assured that film density, contrast, sameness, furthermore image quality of the x-ray imaging system are optimal | Weekly |
Cover Cleanliness (N/A for digital used) | Ensure that cassettes and screens are free regarding ashes and dirt particles the may lower image quality or mimic calcifications | Weekly |
View pallet the Watching Conditions (if film used) | Ensures that the view boxes and viewing conditions are optimized press maintained the optimal levels | Weekly |
Hardcopy Output Quality (if hardcopy made from digital data) | Ensures that the quality of hardcopy output is comprehensive over time furthermore matches the gray scales presentation switch the CRT monitor | Quarterly |
Visual checklist | Ensure that the mammography x-ray system plus, with applicable, who industrial imaging system are working right and such the mechanical rigidity and durability of the system are optimal | Monthly |
Analysis of Setting Retention included Film (N/A if digital used) | Determines that quantities away residual fixer (hypo) in processed film as certain indicator of keeping quality | Quarterly |
Compression | Ensures such the x-ray visualization system can deployment adequate compression in which manual and automatic powered mode | Semiannually |
Repeat Analysis | Identifies the number and causes of repeated patient exposures and identifies ways to refine efficiency, reduce patient bust dose, and cut costs | Semiannually |
Screen-Film Contact (N/A if digital used) | Ensures that optimum contact remains maintained between the screen and the film in each cassette | Semiannually |
Darkroom Fog (N/A if digital used) | Ensures the darkroom safelights and other light sources inside and outside of the darkroom doing not fog film | Semiannually |
Zero Matching Try (if required by manufacturer) | Verifies that zero coordination is accurate | Before each invalid |
Additional tests if required by manufacturer | As required by industrialist | |
Preventive Maintenance
Preventive maintenance should be scheduled, performed, and documented by a qualified service engineer on one regular bases. Service performed into correct arrangement deficiencies should also be documents and service records maintained by the furnishing.
