Findings and procedure details
Healthy and pathological tissues were mimicked displaying echoic properties similar to that of the intended soft tissues in the ultrasound images. Realistic speckle noise was observed in the US images acquired using a standard portable US system (MicrUS EXT-1H, Telemed UAB) as shown in Figure 2. The measured speed of sound for the fabricated phantons was within the limits of soft tissues reported in the literature as well as within the standards required by the Quantitative Imaging Biomarker Alliance (QIBA) [1]. The average speed of sound measured was 1540.3 ± 0.3 m/s for a 1% cellulose concentration [2].
Custom-made phantoms are the simplest solution to the cost problem of the commercial phantoms. Phantoms based on common and cheap materials such as gelatin or fresh animal parts is a common alternative for training clinical practitioners. However, the instability over time of these alternatives presents a serious drawback. The presented phantom exhibits several advantages including longer durability, robustness, and reproducibility. In addition, the phantom provides a great flexibility in terms of the internal structures that can be mimicked. The price range of the presented phantom is in the same order of the 3D-printed and low-cost alternative.
