一位新闻记者-机器人与机器学习的工作人员新闻编辑每日新闻-肿瘤学的新研究-癌症是一篇报道的主题。根据来自德国慕尼黑的新闻,由NewsRx记者报道,研究表明:“尽管新出现的临床证据支持机器人放射外科治疗直径小于4cm的(RCC)肾癌是一种高效的治疗选择,”我们还没有详细研究交付不确定性和相关靶体积边缘。我们评估肾肿瘤破裂内肿瘤运动模式和机器人放射外科的准确性,并通过实时呼吸跟踪来优化治疗边缘。我们的新闻记者从这项研究中获得了一句话,“回顾性分析了165例肾癌连续治疗的分娩日志文件,在规划靶体积(PTV)边缘估计时考虑了五个因素:(a)患者呼吸与肿瘤运动相关模型的模型误差,(b)预测患者呼吸模式Rn的算法的预测误差,©治疗机器人的靶向误差,(d)呼吸运动跟踪系统固有的总精度,(e)覆盖潜在目标旋转所需的边界,PTV旋转达10°,Median肿瘤在上下、左右和前后方向的运动分别为10.5mm、2.4mm和4.4mm。假设最佳基准位置和忽略目标变形,所有对系统不准确性贡献的平方和的根导致上下、左右和前后方向的最小PTV边缘分别为4.3 mm、2.6 mm和3.0 mm。
Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News – New research on Oncology - Carcinomas is the subject of a report. According to news originating from Munich, Germany, by NewsRx correspondents, research stated, “Although emerging clinical evidence supports robotic radiosurgery as a highly effective treatment option for renal c ell carcinoma (RCC) less than 4 cm in diameter, delivery uncertainties and assoc iated target volume margins have not been studied in detail. We assess intrafrac tion tumor motion patterns and accuracy of robotic radiosurgery in renal tumors with real-time respiratory tracking to optimize treatment margins.” Our news journalists obtained a quote from the research, “Delivery log files fro m 165 consecutive treatments of RCC were retrospectively analyzed. Five componen ts were considered for planning target volume (PTV) margin estimation: (a) The m odel error from the correlation model between patient breath and tumor motion, ( b) the prediction error from an algorithm predicting the patient breathing patte rn, ©the targeting error from the treatment robot, (d) the inherent total accur acy of the system for respiratory motion tracking, and (e) the margin required t o cover potential target rotation, simulated with PTV rotations up to 10°. The m edian tumor motion was 10.5 mm, 2.4 mm and 4.4 mm in the superior-inferior, left -right, and anterior-posterior directions, respectively. The root of the sum of squares of all contributions to the system’s inaccuracy results in a minimum PTV margin of 4.3 mm, 2.6 mm and 3.0 mm in the superior-inferior, left-right and an terior-posterior directions, respectively, assuming optimal fiducial position an d neglecting target deformation.”
