Software quafity assurance (QA) is a critical function in the successful development and maintenance of software systems. Because the QA activity adds significantly to the cost of developing software, the cost-effectiveness of QA has been a pressing concern to software quality managers. As of yet, though, this concern has not been adequately addressed in the fiterature. The objective of this ar...

The task group (TG) for quality assurance of medical accelerators was constituted by the American Association of Physicists in Medicine's Science Council under the direction of the Radiation Therapy Committee and the Quality Assurance and Outcome Improvement Subcommittee. The task group (TG-142) had two main charges. First to update, as needed, recommendations of Table II of the AAPM TG-40 repo...

This document was written by Task Force 3 of DentEd III, which is a European Union funded Thematic Network working under the auspices of the Association for Dental Education in Europe (ADEE). It provides a guide to assist in the harmonisation of Dental Education Quality Assurance (QA) systems across the European Higher Education Area (EHEA). There is reference to the work, thus far, of DentEd, ...

Cardiovascular perfusionists have always been interested in quality assurance (QA), most often in the form of equipment maintenance and record keeping. However, these activities have tended to be fragmented. In an attempt to define a more global approach to QA, basic concepts are identified and the steps used to start a formal QA program are illustrated. In the usual approach to QA, three area...

In 2010, the NCS (Netherlands Commission on Radiation Dosimetry) installed a subcommittee to develop guidelines for quality assurance and control for volumetric modulated arc therapy (VMAT) treatments. The report (published in 2015) has been written by Dutch medical physicists and has therefore, inevitably, a Dutch focus. This paper is a condensed version of these guidelines, the full report in...

The research project SESAM (Software Engineering Simulation by Animated Models) aims at providing a training environment for future project managers. The basic idea is to create a model of the software development process that can be interpreted by a simulator. The student using the simulator can control the simulated project interactively, leading it more or less successfully. In this paper, t...

GAMS Development and ARKI Consulting use Quality Assurance (QA) as an integral part of their software development and software publishing process. Research and development in the global optimization area has resulted in promising implementations. Initiated by customer demand, we have been adding three different global codes, BARON, LGO, and OQNLP, to our portfolio of nonlinear optimization solv...

CBSD Technique is based on the idea to develop software systems by selecting appropriate off-theshelf components and then to join them with a well-defined software structure. Because the new software development paradigm is more different from the traditional approach, quality assurance (QA) for CBSD is a new topic in the software engineering community. We survey current component-based softwar...

Proficiency testing (PT), recognized as a quality-assurance (QA) and quality-improvement tool, also has become the cornerstone of the Health Care Financing Administration's (HCFA) regulatory strategy under the revised Clinical Laboratory Improvement Act of 1967 (CLIA '67) and the proposed Clinical Laboratory Improvement Amendments of 1988 (CLIA '88). Use of PT as a regulatory tool corrupts it f...

Finding the actual zero degree of the gantry angle is important in order to perform the mechanical quality assurance (QA) of linear accelerators. To determine real zero, we must locate a "good surface" which could be defined as a plane on the surface of the gantry head that is perpendicular to the direction of radiation. The actual gantry angle could then be defined as the angle between vertica...
