Topic 393: Integrated Photonic Biosensor for Precision Oncology Dose Measurements

放射治疗是一种广泛使用的主要治疗多种恶性肿瘤。然而，物理剂量测量 这不是一种有效的方法，因为不同患者甚至不同类型癌症的生物反应非常 不同的物理剂量。此外，患病组织和正常器官的辐射敏感性也各不相同。 现有的医疗器械（物理剂量计）不满足评估辐射生物反应的所有指标 治疗，特别是以即时护理的方式。IFOS和斯坦福大学正在开发一种快速、便携、易于使用的 和定量剂量测量方法-包括便携式手持传感器和新型纳米探针， 癌组织的实时原位成像。该探头设计用于检测活性氧和氮物质 （RONS）由于辐射和带电粒子治疗而产生。这项创新将提供大大增强的成像 肿瘤学家在放射治疗监测方面的能力。

Radiation therapy is a widely used primary treatment for multiple malignancies. However, physical dose measurement is not an effective approach as the biological response of different patients or even different types of cancers are very different for the same physical dose. Moreover, diseased tissue and normal organ radiation sensitivities also vary. Existing medical devices (physical dosimeters) do not satisfy all the metrics for assessing biological response to radiation therapy, especially in a point-of-care manner. IFOS and Stanford University are developing a rapid, portable, easy-to-use and quantitative dose measurement method – comprising a portable handheld sensor and a novel nanoprobe for rapid, real-time in-situ imaging of cancerous tissue. The probe is designed to detect Reactive Oxygen and Nitrogen Species (RONS) generated due to radiation and charge particle therapy. The innovation will provide greatly enhanced imaging capabilities to oncologists in radiation treatment monitoring.
