Performance Evaluation of an Ultrasonic Imaging System Using Tissue-Mimicking Phantoms for Quality Assurance

Abstract

Diagnostic ultrasound or sonography is an image that can provide valuable information for diagnosing and treating a variety of diseases and conditions. The aim of this research study is to examine the performance and accuracy of the ultrasonic imaging system for the guarantee of diagnosis quality assurance, and to adjust the penetration settings to minimize the time of repeat scans and maintenance duration during research experiments. Measurements in this experiment included the resolution (axial and lateral) and focal zones. Moreover, the evaluation was done by completing all the measurements at different depths on a multipurpose phantom model 539. The phantom was bought from the market and was not fabricated by the author. The measurements were achieved by applying two different transducers: curved and linear (flat). The ultrasound images were obtained and tested by using calipers (electronic), and the estimations and observations were read by using all the taken measurements and images. As a result, because the phantom depths were different, the penetration settings were different too, indicating that the depth impacted the penetrations of the created ultrasound image. Moreover, after the comparison of the recorded measurements and results, it was found that all measurements were within the accepted (standard) value and that the true value was specified by the production of the phantom.

A review of ultrasound contrast media

“…Doppler techniques can be used to measure blood velocity in bigger veins by comparing the relative motion of red blood cells to the surrounding tissue. 8 , 9 This technique is frequently used in clinical settings ( e.g. , obstetrics, 10 assessment of peripheral artery disease, 11 cardiology 12 ).…”

However, this method has drawbacks when applied to areas with poor blood flow, significant tissue motion, and/or low hematocrit percentage.…”

Ultrasound Elastography: Methods, Clinical Applications, and Limitations: A Review Article

“…Ultrasound is a form of imaging that utilizes sound waves at high frequencies. The primary purpose of this function, like other imaging techniques, is to generate visual representations of internal organs and structures within the body [1][2][3]. Typically, clinicians employ it to observe the heart, blood vessels, kidneys, liver, and other organs.…”
