1

Define QA

Any planned and systematic actions necessary to provide
confidence that a sys will perform satisfactorily and safely complying with agreed standards.

2

Define QC

The set of operations intended to maintain or improve quality and includes monitoring, evaluation and maintenance

3

Legal requirements for QA

IRMER17 Reg 32 ádequate testing of performance'
IRMER17 Reg 4 'regular review of procedure to ensure they are effective'
NHS values: commitment to quality of care

5

What is a critical exam?

Tests which ensures safety features and warning devices operate correctly

RPA must be involved

6

What is acceptance testing?

A verification process to by a customer representative to ensure that the contractor has supplied the equipment specified.

Simple check lists a and verification tests

Review mechanical/electrical/ rad safety

7

What are commissioning tests?

Set of tests performed by a customer representative to ensure equipment is ready for clinical use.

Carried out prior to clinical use, can aid optimisation by obtaining baseline test scores.

8

What is routine testing?

Regular testing throughout the equipment's lifetime to monitor performance and ID changes

Subset of commissioning tests

Include action plans for when failure occurs

9

What are maintenance tests?

Engineers tests which compliment routine QA.

Include considerations following mod/ reinstall and repair

10

What is level B and level A QA?

Level B: medical physics led quantitive tests, recc engineer response or actions as required

Level A: Radiographer QA, looking for changes in performance. Sensitive ut most specific. No formal report. Follow action plan if an issue arises.

11

Routine QA guidance From report 91

- Parameters to test
- level of expertise req
- Frequency
- Priority
- Action levels
- Explanatory paragraphs

suggestions
- appoint QA radiographer
- allocate testing time
- document all tes results
- make sure test equipment is available to staff and within calibration

12

What are the 2 types of action level?

Remedial: Issue present but use may continue

Suspension level: error present, halt equipment use

Use documented action plans to take responsibility from front line tester

13

Other report covering QA

Report 32 - Modality specific
107 - Critical exam
89 - Mammo

14

What is retake analysis ?

Review of failed patient images where a retake was required, can identify procedural and QA issues.

15

What are the patient dose measures for each modality?

Standard radiography: individual radiograph: ESD or DAP
Complete session: DAP

Mammo: MGD (mean glandular dose) to standard breast >2.5mGy per film and MGD to patient > 3.5mGy per film

Dental: IO dose at collimator tio or OPG dose

Fluoro: Dose at ES of phantom > 50mGy/min
DAP
