Image optimization for pulmonary nodules detection at lung cancer screening

计算机断层扫描(CT)利用X射线来生成诊断图像。它被广泛用于诊断性身体成像以及早期癌症检测的监视成像。在过去的二十年里，东芝医疗系统公司在CT扫描设计方面进行了大量投资，并开发了独特的尖端CT扫描仪。东芝医疗系统加拿大有限公司是一个更大的团队的一部分，该团队专注于提高诊断准确性、减少辐射剂量和亚秒级CT图像采集，从而几乎不需要患者镇静。东芝已经加入了一项全球范围的行业活动，以开发最佳成像实践，以降低所有患者的辐射剂量，并特别关注儿科患者。该项目是这一开创性工作的一部分，旨在优化图像质量并将CT用于肺结节监测期间的辐射剂量降至最低，肺结节监测是重复胸部CT最常见的适应症之一。

Computed tomography (CT) utilizes X-rays to generate diagnostic images. It is widely used for diagnostic body imaging as well for surveillance imaging in early cancer detection. Over the past two decades, Toshiba Medical Systems has made significant investments in CT scan design and has developed unique, cutting edge CT scanners. Toshiba Medical Systems Canada Ltd is part of a larger team that focuses on improved diagnostic accuracy, radiation dose reduction, and sub-second CT image acquisition such that patient sedation is rarely required. Toshiba has joined a world-wide industry campaign to develop best imaging practices to lower radiation dose for all patients with a specific focus on pediatric patients. This project is part of this pioneer effort and aims to optimize image quality and minimize radiation dose during CT for pulmonary nodule surveillance, one of the most common indications for repeat thoracic CT.
