Where seismic uses small explosions to detect the presence of oil, VibeDx applies gentle vibrations to the skin to detect spinal pathologies and injuries. This technology is based on the discovery that when the spine is exposed to these vibrations, it gives off a unique vibration response used to identify the type, location and severity of a patient's back problem. A recent clinical trial demonstrated that although VibeDx could collect spine displacements in response to vibration, the resolution of these measures was not sufficient in all cases. Specifically, when vibration is applied to the spine, the accuracy of the resulting measure of spinal displacement is dependent on the displacement magnitude; only large displacements can be detected currently. This collaboration between Dr. Zemp, his team and VibeDx will solve this problem by developing a new method to analyze VibeDx data. This method will assess radiofrequency data obtained by ultrasound to improve VibeDx signal accuracy by 3-5x. The result will be a more robust diagnostic tool that has improved commercial possibilities for improving the lives of Canadians with low back pain.

地震技术使用小型爆炸来检测石油的存在，而VibeDx则通过对皮肤的轻微振动来检测脊髓病变和损伤。这项技术是基于一项发现，当脊柱暴露在这些振动中时，它会发出一种独特的振动响应，用于识别患者背部问题的类型、位置和严重程度。最近的一项临床试验表明，尽管VibeDx可以收集振动对脊柱位移的响应，但这些措施的分辨率并不足以满足所有病例。具体来说，当振动作用于脊柱时，由此产生的脊柱位移测量的准确性取决于位移幅度；目前只能检测到较大的位移。Zemp博士及其团队与VibeDx的合作将通过开发一种分析VibeDx数据的新方法来解决这一问题。该方法将评估超声获得的射频数据，将VibeDx信号精度提高3-5倍。结果将是一个更强大的诊断工具，提高了改善加拿大腰痛患者生活的商业可能性。
