Subscription details  

Subscribers have access to the audit program via a 4-year subscription.

Four audits, two Level I, one Level II, and one Level III, are conducted over the term of the 4-year agreement; with one audit conducted per year, per facility, according to the audit schedule. The timing of the audits follows dates that are mutually agreed on by the ACDS and their customers and are conducted within normal working hours. The ACDS provides extensive support prior to, during and after the audits are conducted. 

The Level Ib audit is not part of the scheduled program and is performed at the request of the facility. The Level Ib is typically conducted for new facilities or linacs, or as a part of the follow up process where other audits do not fall inside the Optimal Level. Please contact the ACDS on 03 9433 2220 or via email at acdsatarpansa.gov.au to arrange a quote.

Field trials

A field trial is a developmental stage of an audit. Data gathered informs decision making on phantom design, detector use, correction factors and analysis techniques. Uncertainty budgets and the setting of pass/fail tolerances are refined as predicted tolerances are compared to measurements taken at participating facilities.

A live audit is scored, and audits still in field trial are not scored against the overall audit outcome. Mature field trials are reported with indicative outcomes. ACDS audits which are live or in field trial, are accepted by ROHPG, TROG and state regulators.
