The Australian Clinical Dosimetry Service (ACDS) is a world class independent dosimetry auditing program that aims to provide a high standard of quality assurance and patient safety in radiation therapy across Australia and New Zealand. Operating since February 2011, it offers a multi-level audit service on a four-year subscription basis to radiotherapy providers. Our comprehensive radiotherapy audit services allow benchmarking of audit results of the Australian and New Zealand dataset.

Our vision

We strive to be a world leading dosimetry auditing service by providing the highest level of quality assurance and patient safety in radiation therapy.

Our mission

We aim to guide, support, and improve patient safety and radiotherapy service delivery by:

  • Providing a comprehensive suite of audit modalities covering all common clinical practices
  • Improving national dosimetry capabilities in clinical treatment delivery
  • Offering our services to Australian and overseas radiotherapy centres on a fee-for-service basis

Our mission is aligned with Key Activity 1 of ARPANSA and its initiative to ‘Initiate, maintain, and promote frameworks for protection and safety’.

The ACDS is ISO/IEC 17025 accredited by the National Association of Testing Authorities (NATA) which offers dosimetry audits to meet: 

  • Radiation Oncology Practice Standards (ROPS)
  • Radiation Oncology Health Program Grants (ROHPG) funding
  • Trans-Tasman Radiation Oncology Group (TROG) clinical trial credentialling
  • Jurisdictional radiation license requirements

Radiation Oncology Practice Standards

ACDS audits may be used towards dosimetric intercomparison as outlined in the Radiation Oncology Practice Standards (Part A, Standard 15, Appendix 5; Part B, Standard 15). The audit program ensures compliance with the ROPS to ensure that radiation dose is accurately delivered in a radiation therapy facility and is aligned with the requirements of ROHPG.

Read more about the ROPS.

Trans-Tasman Radiation Oncology Group (TROG) & Clinical Trial Credentialling

ACDS audits may be used towards clinical trial accreditation for TROG trials. Requirements for each individual trial may vary and will be at the discretion of the trial physicist.

Imaging and Radiation Oncology Core (IROC) Houston

The ACDS and IROC Houston Quality Assurance Center have a Memorandum of Understanding of Mutual Recognition of the dosimetric audit equivalence for the Level I OSLD audits. The agreement recognises technical equivalence and the frequency of both organisations’ OSLD mail out audit. In practice this means that a facility may provide ACDS Level I OSLD results where there is a requirement for an IROC OSLD audit (such as in a clinical trial). This agreement is maintained by regular intercomparisons of the mail out audit by the ACDS and IROC.

Level I audits

The Level I mail out audit is an independent measurement of linac output under reference conditions.

Level Ib audits

The Level Ib audit offers a more accurate measurement of the Linac output than the Level I audit. ACDS staff visit the facility and perform on-site measurements using ACDS dosimetry equipment.

Level II audits

The Level II audit is a diagnostic test of the Treatment Planning System performance.

Level III audits

The Level III audit is an end-to-end test of the radiotherapy treatment pathway.

ACDS audit program

The ACDS audit program is available via subscription and includes Level I, Level II and Level III audits.

Clinical Advisory Group

The Clinical Advisory Group is a panel of independent experts appointed by the CEO of ARPANSA to provide clinical and technical oversight and support to the ACDS.

Staff

The ACDS team is comprised of highly trained and experienced professionals to carry out the dosimetry audit service, research and development programs and utilise external auditors.

ACDS Australia and New Zealand datasets

The Australia and New Zealand datasets show the dose variation as measured by the ACDS in audits to date excluding follow up audits.

MMOSS: Motion Management Overview Survey Summary

In December 2020, the ACDS conducted a survey of its subscribers on respiratory motion management. The aim of the survey was to capture both what motion management techniques were used by each facility, as well as how the techniques were implemented practically.
