PURPOSE To develop and implement a failure mode and effect analysis (FMEA)-based commissioning and quality assurance framework for dynamic multileaf collimator (DMLC) tumor tracking systems. METHODS A systematic failure mode and effect analysis was performed for a prototype real-time tumor tracking system that uses implanted electromagnetic transponders for tumor position monitoring and a DML...

PURPOSE To report our early experiences with failure mode and effects analysis (FMEA) in a community practice setting. METHODS The FMEA facilitator received extensive training at the AAPM Summer School. Early efforts focused on department education and emphasized the need for process evaluation in the context of high profile radiation therapy accidents. A multidisciplinary team was assembled ...

Nowadays safety at workstations is so important for managers and they try to ensure that workstations meet minimum requirements. There are some research about using FMEA (Failure mode and effects analysis) to increase the safety at work especially in food industries and hospitals, but all of them have concentrated on safety in special points of view and they are not applicable for all fields. I...

Failure Mode and Effects Analysis (FMEA) is a systematic method for procedure analyses and risk assessment. It is a structured way to identify potential failure modes of a product or process, probability of their occurrence, and their overall effects. The basic purpose of this analysis is to mitigate the risk and the impact associated to a failure by planning and prioritizing actions to make a ...

Constructability analysis and the resulting adjustments in facility design have a significant potential in improving cost effectiveness of construction projects. However, traditional constructability knowledge acquisition techniques are the key barrier to successful constructability improvement. A new approach to automated constructability lessons-learned documentation and constructability anal...

Requirement elicitation is an analysis, abstraction, synthesis, extracted process which obtains real and correct software requirements from users' demands, thoughts and expectations. The accuracy and integrity of software requirements is crucial to the success of the software. Although many software engineering techniques have been applied, incomplete, inaccurate or inconsistent requirements st...

Failure Mode and Effects Analysis (FMEA) is a technique used in the manufacturing industry to improve production quality and productivity. It is a method that evaluates possible failures in the system, design, process or service. It aims to continuously improve and decrease these kinds of failure modes. Adaptive Resonance Theory (ART) is one of the learning algorithms without consultants, which...

Risk assessment is a valuable tool for selection and optimization of rapid mycoplasma testing methods. Mycoplasma testing is a requirement at various stages in the production process for cell therapy products. Standard methods take at least 28 days and are not appropriate lot release tests for products with short shelf-lives. A review of 21 commercially available mycoplasma tests and ranking of...
