简介:摘要在经济与社会快速发展的今天,我国民众对于医疗服务的要求也在不断提高,这一提高虽然在客观上推动了医疗事业的发展,但当下我国很多医院中存在的问题也就此暴露出来,医疗器械维修问题就是这一其中的代表,为此笔者就医院医疗企业维修中存在的问题展开了具体研究,并提出了解决问题的具体对策,希望这一内容能够为我国相关医疗机构带来一定启发。
简介:目的:探讨基于影像组学的肺结节恶性程度预测。方法:对肺部图像影像数据库(TheLungImageDatabaseConsortium,LIDC)-IDRI(ImageDatabaseResourceInitiative)中604例肺结节患者的CT图像进行分析,其中含肺结节的CT图像共2803幅,医师手工勾画肺结节轮廓。根据肺结节诊断标准,共提取96个灰度、形态和纹理高通量特征,输入基于随机森林的多类分类器进行恶性程度预测。恶性程度分为5级,以数字1~5表示。随机选取1000幅CT图像作为训练样本,剩余的1803幅CT图像作为测试样本,实验重复10次。结果:对于单个肺结节,5类恶性程度的平均预测准确率为77.85%。对于每一类预测,曲线下面积(areaundercurve,AUC)均在0.94以上。对于每例患者,肺结节恶性程度的预测准确率为75.16%。结论:该研究提出的基于影像组学的方法对肺结节恶性程度的预测性能良好,可为临床诊断提供可靠的辅助信息,以利于早期发现病灶。
简介: 摘 要:医院内的许多医疗活动,如各项检查等都需要依赖医疗设备,随着医学技术的发展,设备类型也逐渐增多,所以现阶段医院的一项重要的工作就是医疗设备的维护与维修。近几年,在医学技术不断改革的背景下,医疗设备与过去相比有了更高的技术含量,运行过程中设备的潜在问题变得十分隐秘,大大增加了维修难度。在维护与维修医院医疗设备时,必须实现维修模式的多元化,共享资源,才能使设备的维护与维修水平不断提高。文章分析了目前维修与维护医院医疗设备中的困难与挑战,探讨了有效的维护维修策略与实施模式。 关键词:医院医疗设备 困难 维修维护策略 模式 Abstract: many medical activities in hospitals, such as examinations, all need to rely on medical equipment. With the development of medical technology, the type of equipment is also increasing. Therefore, an important work of the hospital is maintenance and repair of medical equipment at this stage. In recent years, under the background of continuous reform of medical technology, medical equipment has higher technology content than before. During operation, the potential problems of equipment become very secretive, which greatly increases the difficulty of maintenance. When maintaining and maintaining hospital medical equipment, we must realize diversification of maintenance mode and share resources, so that the level of maintenance and repair of equipment will be continuously improved. This paper analyzes the difficulties and challenges in the maintenance and maintenance of hospital medical equipment, and discusses the effective maintenance strategy and implementation mode.
