Technical Specifications
Based on the national standard GB10152—2009 and tailored to the technical requirements for ultrasound phantoms in training applications, the technical parameters of this phantom are as follows:
Speed of Sound within Internal TM Material (Human Tissue-Mimicking Material): (1540 ± 10) m/s (at 23°C ± 3°C)
Slope of Background Acoustic Attenuation Coefficient: Not greater than 0.10 dB/cm/MHz (at 23°C ± 3°C)
Left Acoustic Window Material: 70 µm thick polyester film.
Left Acoustic Window Opening Dimensions: 140 mm × 150 mm.
The phantom features a cubic overall structure, with its four sides bonded together using acrylic (Plexiglas) panels; the entire assembly contains no metallic components. The structural layout is illustrated in Figure 2. The interior of the phantom consists of a background tissue-mimicking material composed of a transparent aqueous gel, which also encapsulates a semi-transparent aqueous gel structure shaped like a human liver. Embedded within this semi-transparent, liver-mimicking structure are several dark-colored cylindrical targets, distributed uniformly throughout the "liver" volume. The axes of these cylindrical targets run parallel to the thickness dimension of the phantom; these targets serve as reference points for puncture training. Under both ultrasound and X-CT imaging modes, these targets generate distinct image contrast relative to the surrounding tissue-mimicking background material.
The top surface of the phantom is covered by a 1.5 mm thick semi-transparent silicone rubber membrane, which is secured in place by the rim of an outer water-bath frame. This outer frame is constructed from plastic and is fastened to the edges of the phantom's housing via hand-tightened screws located on all four sides. The silicone rubber membrane functions as both the acoustic window and the puncture entry point, while also serving the purpose of retaining the internal aqueous gel fluid.
