脊柱模体，用于骨密度仪的测试
BioClinica's "Bona Fide Phantom" (BFP), is a quality control tool for Dual-Energy X-ray Absorptiometry (DEXA) instruments, which features an acrylic-embedded calcium hydroxyapatite (CHA) step-wedge. Advanced design features make it the best choice for assessing DEXA instrument stability. You can successfully use the BFP on all mainstream DEXA instruments.
The BFP offers a range of densities (0.7 - 1.5 g/cm2), to verify instrument function over the clinically relevant range, not just at a single, "healthy" BMD. Linearity of BMD over the clinically range is critical for full instrument evaluation. The phantom uses a CHA insert for direct assessment of bone density accuracy. The CHA insert is compliant with FDA guidelines for cross-calibration phantoms for clinical trials.
The BFP is cast in acrylic and comes with its own carrying case for easy handling. The tote remains on the phantom during scanning and does not affect BMD readings, allowing rapid placement and removal for the phantom from the bed. A flight case is available as an option.

BioClinica的“Bona Fide Phantom”（BFP）是用于双能X射线吸收光度计（DEXA）仪器的质量控制工具，其具有丙烯酸嵌入的羟基磷灰石（CHA）楔形楔。先进的设计功能使其成为评估DEXA仪器稳定性的zui佳选择。您可以在所有主流DEXA仪器上成功使用BFP。
BFP提供一系列密度（0.7 - 1.5 g / cm2），以验证临床相关范围内的仪器功能，而不仅仅是单一的“健康”BMD。BMD在临床范围内的线性关系对于全面的仪器评估至关重要。幻影使用CHA插入物直接评估骨密度精度。CHA插入符合FDA针对临床试验的交叉校准模型的指南。
BFP采用丙烯酸铸造，并配有自己的便携箱，方便操作。在扫描过程中，手提箱保持在幻影中，不影响BMD读数，从而可以从床上快速放置和移除幻影。飞行箱可作为选项提供。
