Phantom-based quality assurance measurements in B-mode ultrasound
BACKGROUND Recommended phantom-based quality assurance measurements in B-mode ultrasound (US) may be tedious. For the purpose of cost-effective US quality assurance it is important to evaluate measurements that effectively reflect the quality of US scanner. PURPOSE To find out which recommended phantom-based quality assurance measurements are effective in detecting dead or weak transducer ele...
متن کاملComparison of ultrasound quality assurance phantom measurements from matched and mixed scanner‐transducer combinations
Our goal in this work was to compare the results of common phantom tests made using matched and mixed ultrasound (US) scanner-transducer combinations. Sets of common US quality assurance (QA) measurements were made using matched US scanner-transducer combinations (i.e., transducers purchased for use with a particular scanner), as well as unmatched (mixed) combinations. Measurements of vertical ...
متن کاملDaily quality assurance phantom for ultrasound image guided radiation therapy
A simple phantom was designed, constructed, tested, and clinically implemented for daily quality assurance (QA) of an ultrasound-image-guided radiation therapy (US-IGRT) system, the Restitu Ultrasound system (Resonant Medical, Montreal, QC). The phantom consists of a high signal echogenic background gel surrounding a low signal hypoechoic egg-shaped target. Daily QA checks involve ultrasound im...
متن کاملThermochromic phantom for therapeutic ultrasound daily quality assurance
Background/introduction Errors in power output ranging from −100% to +210% have been reported in a multitude of physiotherapy transducers.[1] Differences in power output can arise even after careful calibration on an annual or bi-annual schedule, which can either result in harm to the patient or non-effective treatment. Therefore, easy implementation of daily quality assurance is of great impor...
