A routine QA test phantom for radiography systems.
PIX-13 is used to provide an ongoing check of imaging performance, particularly those aspects which are most liable to deterioration.
PIX-13 should be used with either PMMA/Cu or Al attenuator plates (available separately).

Measure:
• Dynamic range (7 different thickness steps Cu)
• Resolution limit (0.6 to 5.0 LP/mm)
• Low-contrast large-detail detectability (6 details, 15mm diameter)
• X-ray to light field alignment markers
