2024年7月26日 · sfrt在大体积头颈部肿瘤、软组织肉瘤、肺癌及宫颈癌中显示较好的局部控制率，对中晚期大肿瘤的总体局控率高达80％～90％。我科对大体积肿瘤进行 sfrt 联合常规放疗的实例： 患者一， 上颌窦鳞癌术后放化疗后复发

2021年10月22日 · Spatially Fractionated Radiation therapy (SFRT) has a history of over 100 years. The principle of SFRT is distinctive from the standard radiation approaches, as it treats the total tumor with a non-uniform dose, effectively treating the tumor while staying within normal tissue tolerance of the surrounding structures.

2022年12月1日 · SFRT治疗效果不依赖组织的氧合，而FLASH治疗恰相反。目前，两种技术都带有复杂的剂量测定和安全问题，需要进一步研究。 以上是第一届FRPT会议中Prezado教授关于空间分割放射治疗所做的发言。

2021年1月8日 · Spatially fractionated radiation therapy (SFRT) may address this limitation because this technique can deliver high-dose radiation to discrete subvolume vertices inside a tumor target while restricting the remainder of the target to a safer lower dose.

2024年3月9日 · Spatially fractionated radiation therapy (SFRT) has shown promise in improving local tumor control while minimizing toxicity in various bulky advanced malignancies. Foundational experience with GRID-based SFRT has shown drastic and rapid symptomatic responses and favorable local control in palliative treatment for bulky metastatic tumors.

State Fire Rescue Training delivers training to all disciplines of emergency response, including fire departments, rescue squads, emergency medical services, local governments, businesses, and industries.

Spatially Fractionated Radiation Therapy (SFRT), often referred to as “grid” or “lattice” therapy when used clinically, is a treatment technique that intentionally delivers a heterogeneous dose distribution characterized by alternating regions of high and low doses throughout a tumor [1,2].

2023年2月18日 · This article tells the story of a medical physicist's journey to understand SFRT which started by accident more than 15 years ago. For decades, clinical application and preclinical research have shown that spatially fractionated radiation therapy (SFRT) can achieve a magically high therapeutic index.

2024年8月23日 · 空间分割放射治疗（sfrt）即空间分割放疗，又称网格疗法，是一种放射治疗技术，原理是在肿瘤内部构建不均等剂量分布，在有效控制肿瘤的同时保持周围正常组织的剂量在可耐受范围内。

Spatially Fractionated Radiation Therapy (SFRT) is a form of radiotherapy that delivers a single large dose of radiation within the target volume in a heterogeneous pattern with regions of peak dosage and regions of under dosage. SFRT types can be defined by how the heterogeneous pattern of radiation is obtained.
