　　Bone density measurement evaluation phantomIt is a key tool for calibration and quality control of radiation therapy equipment. It adopts a cylindrical design with a diameter of 80mm and a height of 60mm, embedded with four symmetrically distributed small cylinders (diameter 20mm, length 40mm), corresponding to hydroxyapatite bone density values of 50mg/cm3, 100mg/cm3, 200mg/cm3, and 300mg/cm3, covering the clinically relevant density range. The main body of the mold is made of polyurethane resin, a soft tissue equivalent material with a purity of ≥ 99%, to ensure a high match with the acoustic and radiation absorption characteristics of human tissue, and to meet the requirements of YY/T1466-2016 standard for material homogeneity and stability. Part of the phantom series adopts a water equivalent resin body with three different hydroxyapatite contents of fillers, which can simulate the physiological density gradient of cortical bone and cancellous bone. Its calibration accuracy reaches ± 0.5mg/cm3, and the geometric dimension error is controlled within ± 0.1mm. This phantom is mainly used for calibration of dual energy X-ray (DEXA) and quantitative CT (QCT). By comparing the measured values of the equipment with the known density values of the phantom, the accuracy of the instrument is verified and systematic errors are eliminated. In clinical applications, it provides a benchmark for the diagnosis of osteoporosis, assists radiation health professionals in assessing fracture risk and developing treatment plans. At the same time, the phantom supports epidemiological investigations and drug dynamic monitoring, and tracks device performance drift through regular use of quality assurance phantoms (QA phantoms) to ensure comparability of long-term test results. In addition, some phantom systems integrate validation phantoms (CP phantoms) with specialized analysis software to achieve three-dimensional quantitative analysis of spinal bone density, overcoming errors caused by bone hyperplasia or vertebral deformation in traditional two-dimensional detection. Manufacturers can customize equivalent substitute materials or adjust geometric parameters according to their needs, but the basis for the change must be clearly stated in the technical documentation to ensure the equivalence of different models in bone density evaluation. This product has been widely used in manufacturers of radiation therapy equipment, research institutions, and radiation therapy facilities, providing core guarantees for the accuracy and reliability of the system.
