Accurate polyp sizing during endoscopy is crucial for cancer risk assessment but is hindered by subjective methods and inadequate datasets lacking integrated 2D appearance, 3D structure, and real-worl
The dataset is from the Kaggle "TReNDS Neuroimaging " Competition (https://www.kaggle.com/c/trends-assessment-prediction), provided by the Tri-Institutional Georgia State University/Georgia Institute
开展检定项目名称：医用CT X射线辐射源。医用诊断螺旋计算机断层摄影装置（CT）X射线辐射源是根据人体不同组织和病变对X射线吸收的系数不同，利用高灵敏光子探测技术，先进的数据处理方法和显示技术，将组织结构的立体形象和病变情况用一系列组织层面图像表示出来。医用CT X 射线辐射源检定装置由标准计量仪和CT模体组成。诊断水平剂量计必须是电离室型或半导体型的剂量计。开展检定所依据的计量检定规程或开展校准
