This paper details a research project undertaken to assess the extent of adoption of quality assurance (QA) certification by Australian software developers. A brief history of government QA policy, the catalyst in the sudden interest in certification, is included. Primary data for the study were gathered from a survey of 1,000 Australian software developers, and were used to determine the exten...

This study evaluated the feasibility of utilizing a 3D-printed anthropomorphic patient-specific head phantom for patient-specific quality assurance (QA) in intensity-modulated radiotherapy (IMRT). Contoured left and right head phantoms were converted from DICOM to STL format. Fused deposition modeling (FDM) was used to construct an anthropomorphic patient-specific head phantom with a 3D printer...

Quality assurance (QA) in higher education plays an increasingly important role in many university systems worldwide regarding the competitiveness of universities and entire national or regional university systems. The origins of what we consider today as systematic QA (e.g. accreditation processes, external evaluation, audits, etc.) can be traced back to the emergence of the new public managem...

We present an example when profile measurement and modeling of an Elekta Agility multileaf collimator (MLC) had a large effect specifically on arc therapy plan quality assurance (QA) results using ArcCheck. ArcCheck absolute dose measurements of these plans were systematically lower than planned by 3-10%. Failing QA results were seen even with unmodulated static and conformal arcs. Furthermore,...

Component-based software development approach is based on the idea to develop software systems by selecting appropriate off-the-shelf components and then to assemble them with a well-defined software architecture. Because the new software development paradigm is much different from the traditional approach, quality assurance (QA) for component-based software development is a new topic in the so...

As radiation therapy transitions from intensity modulated radiation therapy (IMRT) to volumetric modulated arc therapy (VMAT) it is important to consider the quality assurance (QA) of VMAT plans in light of what has previously been learned and developed in IMRT QA. This technical note assesses if IMRT based plan QA software, which has reduced the need in IMRT for phantom dose measurements on th...

The Children's Oncology Group (COG) has a strong quality assurance (QA) program managed by the Imaging and Radiation Core (IROC). This consists of credentialing centers providing real-time management each case for protocol compliant target definition radiation delivery. In International Society Pediatric (SIOP), lack an available, reliable online data platform been challenge European Paediatric...

This chapter presents a teaching framework for agile quality—that is, the way quality issues are perceived in agile software development environments. The teaching framework consists of nine principles, the actual implementation of which is varied and should be adjusted for different specific teaching environments. This chapter outlines the principles and addresses their contribution to learner...

OBJECTIVE To assess the role of sanctions as the highest level of enforcement in Australia's residential aged care quality assurance (QA) system. DESIGN ANALYSIS of secondary data on accreditation activities and outcomes from 1999-2000 to 2007-08, extracted from the Annual Report on the Aged Care Act 1997. SETTING A total of 138 sanctioned homes among all aged care homes in Australia (n ...

To ensure the safe operation of mammography units, acceptance tests and quality assurance (QA) protocols have been developed by the American Association of Physicists in Medicine (AAPM), Engineers Registration Board, and International Atomic Energy Agency. Eight mammography units manufactured by five different manufacturers located in hospitals in our region were investigated following the AAPM...
