The demand for interfaces that allow users to interact with computers in an intuitive, effective, and efficient way is increasing. Question Answering (QA) systems address this need by answering questions posed by humans using knowledge bases. In recent years, many QA systems and related components have been developed both by practitioners and the research community. Since QA involves a vast num...

Huntington's disease (HD) is a neurological degenerative disease and quinolinic acid (QA) has been used to establish HD model in animals through the mechanism of excitotoxicity. Yet the specific pathological changes and the underlying mechanisms are not fully elucidated. We aimed to reveal the specific morphological changes of different striatal neurons in the HD model. Sprague-Dawley (SD) rats...

Development and comparison of spine-shaped phantoms generated by two different 3D-printing technologies, digital light processing (DLP) and Polyjet has been purposed to utilize in patient-specific quality assurance (QA) of stereotactic body radiation treatment. The developed 3D-printed spine QA phantom consisted of an acrylic body phantom and a 3D-printed spine shaped object. DLP and Polyjet 3D...

MRI simulation is the process of acquiring high fidelity, high contrast resolution magnetic resonance images to identify true disease extent and proximity relative to adjacent organs at risk (OAR) for the purposes of radiation treatment planning. MRI simulation can be performed using dedicated MRI scanners in radiotherapy departments [1] or using MRI scanners sited in other departments as share...

Quality assurance (QA) in higher medical education involves the development, sustenance, improvement, and evaluation of the standard of training of medical professionals. In health care delivery, QA focuses on guaranteeing and maintaining a high standard of the service provided in different health care systems. When the service delivered by the care provider is in accordance with what the recip...

Mobius FX, an add-on software module from Mobius Medical Systems™ for intensity-modulated radiation therapy (IMRT) quality assurance (QA), uses linac treatment logs to efficiently calculate and verify the 3D dose delivered to patients. An advantage of the Mobius FX module is that it does not require device positioning. In this study, we compared the Mobius FX with another QA option, ArcCheck, a...

Modern healthcare achieved great progress in developing and manufacturing medical devices, treatment procedures and drugs to serve individual patients. However, relatively little technical talent and material resources have been devoted to improving the overall health care delivery process as a system. Discrete-event simulation (DES) models and queuing analytic (QA) theory are the most widely a...

Due to a lack of information regarding the current clinical experience of IMRT QA for a large and varied plan population, we reviewed our patient-specific IMRT quality assurance (QA) results for 13,003 treatment plans from 13 distinct treatment sites from a six-year period. QA records were reviewed for dose difference (single point with ion chamber measurement; ± 3% agreement criteria) and perc...
