An Audit Of A Hospital-Based Doppler Ultrasound Quality Control Protocol Using A Commercial String Doppler Phantom, S. Cournane, A. J. Fagan, Jacinta Browne
Articles
Results from a four-year audit of a Doppler quality assurance (QA) program using a commercially available Doppler string phantom are presented. The suitability of the phantom was firstly determined and modifications were made to improve the reliability and quality of the measurements. QA of Doppler ultrasound equipment is very important as data obtained from these systems is used in patient management. It was found that if the braided-silk filament of the Doppler phantom was exchanged with an O-ring rubber filament and the velocity range below 50cm/s was avoided for Doppler quality control (QC) measurements, then the Maximum Velocity Accuracy (MVA) …
A Review Of Doppler Ultrasound Quality Assurance Protocols And Test Devices, Jacinta Browne
A Review Of Doppler Ultrasound Quality Assurance Protocols And Test Devices, Jacinta Browne
Articles
In this paper, an overview of Doppler ultrasound quality assurance (QA) testing will be presented in three sections. The first section will review the different Doppler ultrasound parameters recommended by professional bodies for use in QA protocols. The second section will include an evaluation and critique of the main test devices used to assess Doppler performance, while the final section of this paper will discuss which of the wide range of test devices have been found to be most suitable for inclusion in Doppler QA programmes. Pulsed Wave Spectral Doppler, Colour Doppler Imaging QA test protocols have been recommended over …
