Full title and description

STB DIN 6868-150: Image quality assurance in diagnostic X‑ray departments — Part 150: Acceptance test of medical radiographic and fluoroscopic X‑ray equipment. The standard specifies procedures and measurable acceptance criteria for verifying image quality, beam geometry, and related performance parameters of radiographic and fluoroscopic systems used in medical diagnostics.

Abstract

This part of DIN 6868 defines the acceptance-test methods, test objects and measurement procedures used to assess radiographic and fluoroscopic X‑ray equipment (including digital subtraction angiography and certain digital volume tomography configurations). It covers image quality checks (spatial resolution, contrast, homogeneity), beam/field alignment and size, dynamic range, and relevant dose/beam quality measurements required at installation or following major modifications.

Scope

This standard applies to acceptance testing of medical X‑ray equipment for projection radiography and fluoroscopy, including systems used for digital subtraction angiography and certain digital volume tomography configurations with integrated recording. It specifies required test objects (phantoms), measurement setups, performance parameters to be measured, and acceptance criteria intended for initial installation testing and formal handover. The scope excludes routine constancy/QA schedules that follow acceptance, which are addressed in other parts of the DIN 6868 series.

Key topics and requirements

• Mandatory acceptance measurements for image quality: spatial resolution (line‑pair/MTF checks), low‑contrast detectability, and dynamic range evaluation.
• Verification of effective radiation field size, collimation/beam alignment and centring relative to image receptor.
• Homogeneity/uniformity checks of the receptor and imaging chain.
• Procedures for dose and beam quality measurements required for acceptance (using appropriate dosimetry and test phantoms).
• Specification of test phantoms and pattern elements for repeatable assessments (including manufacturer and user guidance for phantom use in acceptance tests).
• Pass/fail criteria and reporting formats for documenting acceptance test results and deviations at installation.

Typical use and users

Primary users are medical physicists, certified radiology equipment inspectors, clinical engineers, hospital technical staff and manufacturers’ field service engineers responsible for installation and formal acceptance of radiography/fluoroscopy systems. Regulatory bodies and accreditation organizations may also reference this document when assessing compliance with national X‑ray regulations and formal acceptance procedures.
