光谱CT 7500 RT.[图片由飞利浦提供]飞利浦（纽约证券交易所：PHG）今天宣布，FDA为其新的基于探测器的光谱计算机断层扫描（CT）放射治疗解决方案授予510（k）许可。

The company says its Spectral CT 7500 RT marks the next step in personalized cancer care. It integrates the unique tumor visualization and tissue characterization capabilities of spectral CT into cancer treatment and planning. With it, radiation oncologists can precisely target radiation therapy to the specific physiological characteristics of a patient’s tumor.

该公司表示，其光谱CT 7500 RT标志着个性化癌症护理的下一步。它将光谱CT独特的肿瘤可视化和组织表征功能整合到癌症治疗和规划中。有了它，放射肿瘤学家可以精确地针对患者肿瘤的特定生理特征进行放射治疗。

This minimizes damage to healthy surrounding tissue and reduces potential unwanted side effects..

这将对健康周围组织的损害降至最低，并减少潜在的不良副作用。。

Spectral CT 7500 RT combines true conventional and spectral CT capabilities in a single scan to integrate into existing workflows. Philips said it’s the first radiation therapy CT scanner to offer respiratory-gated spectral imaging. This gives radiation oncologists all benefits of 4D conventional CT, plus improved visualization and quantification..

Spectral CT 7500 RT在一次扫描中结合了真正的常规和光谱CT功能，以集成到现有的工作流程中。飞利浦表示，这是第一台提供呼吸门控光谱成像的放射治疗CT扫描仪。这为放射肿瘤学家提供了4D常规CT的所有好处，以及改进的可视化和定量。。

Philips says its innovation helps reduce the costs of additional scans while enhancing accuracy and enabling more effective treatment plans. The company says Spectral CT demonstrated the ability to reduce proton stopping-power ratio (SPR) error by more than 50% compared to conventional CT. This improves the accuracy of radiation treatment and spares healthy tissue..

飞利浦表示，其创新有助于降低额外扫描的成本，同时提高准确性并实现更有效的治疗计划。该公司表示，与传统CT相比，光谱CT能够将质子停止功率比（SPR）误差降低50%以上。这提高了放射治疗的准确性，并节省了健康组织。。

“Tumor delineation, beam attenuation, and respiratory motion are critical factors in radiotherapy planning. The spectral information provided by Spectral CT 7500 RT enhances tissue characterization, enabling wider access to highly personalized and precisely targeted treatment for more patients without adding extra steps to current radiotherapy workflows,” said Dan Xu, global business leader of CT at Philips..

飞利浦CT全球业务负责人Dan Xu说：“肿瘤描绘、光束衰减和呼吸运动是放射治疗计划的关键因素。spectral CT 7500 RT提供的光谱信息增强了组织表征，使更多患者能够更广泛地获得高度个性化和精确靶向治疗，而无需为当前放射治疗工作流程增加额外步骤。”。。
