- Equipment specification
- Critical examination
- Acceptace testing
- Clinical use
- Routine testing
- (clinical examination again then back to clinical use, if adjustments are made)
Identify essential critera and desirable elements of the equipment you need and put together a specification.
This then goes into a tendering process, where you shrtlist potential suppliers and these suppliers make site visits where equipment testing is done.
Things to consider during installation process.
- Where is it being delivered to?
- Is everyone aware of the change?
- Who is managing the project?
Four stages of checking equipment
- Critical examination - Before clinical use
- Acceptance- Before clinical use
- Commisioning- Before clinical use
- Routine performance testing- During Clinical use.
IRR 2017- States that critical examination should be done for all equipment. The installer is responsible for this, but is carried out by the RPA
- Emergency off button test
- Automatic Exposure control
- Warning signs
- Door locks
- All labels on equipment
- Couch movement and brakes are tested
Employers should not allow equipment to be used if it is unsatisfactory.
This is done by medical physics
Record keeping is important.
This is normally carried out at the same time as commissioning
Baseline views determined for future QA testing.
Also done by Medical physics. or company engineers.
Standard operating procedures are written for the equipment
During clinical use the quality of service should be monitored.
Level A checks: ( 1 to 3 monthly)
- Distance and scale checks
- Output measurements
Level B checks: (yearly, as these tests are more analytical and require additional equipment.
- Exposure time
- Image uniformity
- Radiation out put repeatability
- systematic monitoring
- Evaluation of various aspects of equipment
- Ensures that standards of quality are met
- Ensures the continued production of diagnostic images with appropriate image quality with the dose being as low as reasonably practiceable.
- Identifies faults or deterioration
- Maintains image quality
- Protects staff and pts
- Keeps rad dose ALARP
