OsteoProbe® RUO是在體測量骨組織材料性質(zhì)的**儀器，是實(shí)驗(yàn)室和臨床研究中測量骨質(zhì)量的有力工具。OsteoProbe® RUO是一種便攜式單手操作微壓痕儀，與測量骨密度的放射性方法（X射線、DXA和CT）具有不同的原理，它使用參考點(diǎn)壓痕技術(shù)來檢測材料對局部壓力的抵抗性。
應(yīng)用范圍：
OsteoProbe® RUO可測量骨組織的材料性質(zhì)，有助于加深對骨量的認(rèn)識。骨由礦物質(zhì)和有機(jī)物（骨膠）組成，現(xiàn)有的技術(shù)只有提供有關(guān)礦物質(zhì)的信息，關(guān)于有機(jī)物的信息很少。由于缺少在體測量方法，臨床研究中難以得到骨的材料性質(zhì)，參考點(diǎn)壓痕技術(shù)則解決了這一難題，使得研究人員可以測量和監(jiān)測骨量的改變。
OsteoProbe® RUO measures and quantifies material properties of bone, providing a clearer understanding of Bone Quality. Bone is composed of mineral and organic (Bone Glue) building blocks. Current techniques provide detailed information about the mineral aspect but we suffer from limited information about the organic. Learn more about Bone Quality.
In the clinical setting, material properties of Bone Quality have been ignored due to the lack of a method for in vivo measurement. Reference Point Indentation (RPI) is a technique bringing change to the current situation in a clinical research setting. RPI enables researchers to have an in vivo method for directly measuring material aspects of bone quality. With RPI, researchers can measure and monitor longitudinal changes in the material quality of bone.
