As a key tool for performance testing of magnetic resonance imaging (MRI) equipment, the spherical water model has a core structure made of high-purity PMMA (polymethyl methacrylate) precision machining, which has excellent transparency and corrosion resistance. The standard spherical design has an inner diameter of 20cm, and some models, such as gamma knife specific models, can reach a diameter of 160mm. The mold is filled with a specific concentration of copper solution to simulate the proton density (1.0-1.5g/cm3) and relaxation time (T1: 200-300ms, T2: 80-150ms) of human tissue, and can systematically detect 11 core parameters of MRI equipment. Specifically, it includes magnetic field uniformity (accuracy ± 0.03ppm), signal-to-noise ratio (SNR ≥ 120), spatial resolution (relatively high 11 line pairs/cm), low contrast sensitivity (0.5-2mm gradient change unit), geometric linear distortion rate (≤ 1.5%), and layer thickness verification (± 0.1mm). Its unique spherical structure combined with inclined positioning design supports multi plane scanning positioning, and modular components can quickly identify the imaging orientation of the equipment, simplifying the evaluation process of multi slice systems.
At the application level, the spherical water phantom provides a standardized testing solution without human intervention for magnetic resonance equipment acceptance, daily quality control, and scientific research evaluation. Engineers can use this model to quantify the uniform imaging area of the equipment, eliminating the need for uniform field operation and obtaining uniform area data. Even without Tesla meter assistance, key performance analysis can be completed. The innovative double-layer shielding structure and temperature control design (fluctuation ± 0.2 ℃) ensure its detection stability in environments with 7T ultra-high field strength and gradient magnetic field switching frequency of 200T/m/s. In addition, the phantom effectively overcomes the impact of liquid shaking on quality control results and is suitable for systematic evaluation of equipment by research institutes, third-party laboratories, and radiation healthcare device manufacturers. In the field of radiosurgery, such as the accuracy detection of gamma knife treatment, the design of the spherical geometric center coinciding with the positioning marker point can achieve CT/MRI dual-mode spatial position consistency verification and improve the accuracy of focal spot landing point deviation detection. In summary, spherical water models have become a quality inspection tool for ensuring the consistency and stability of imaging equipment due to their precise parameters and multifunctional applications.
