JSRT(Japanese Society of Radiological Technology Database)
收藏资源简介:
日本放射线学会 (JSRT) 与日本放射线学会 (JRS) 于 1998 年合作创建 (*1) 有胸肺结节和无胸肺结节的标准数字图像数据库 (JSRT 数据库)。此后,JSRT 数据库已被世界上许多研究人员用于各种研究目的,例如图像处理、图像压缩、图像显示评估、计算机辅助诊断 (CAD)、图片存档和通信系统 (PACS),以及用于培训和测试.・对 ROC 分析有用(154 个结节和 93 个非结节图像)・高分辨率(2048 x 2048 矩阵大小,0.175mm 像素大小)・宽密度范围(12 位,4096 灰度)・通用图像格式(无标题,大-endian 原始数据)・对诊断培训和测试有用・附加信息:患者年龄、性别、诊断(恶性或良性)、结节的 X 和 Y 坐标、结节位置的简单图、结节视觉检测的细微程度
The Japan Radiological Society (JSRT) and the Japan Radiological Society (JRS) jointly developed the standard digital image database (JSRT Database) containing and excluding pulmonary nodules in 1998 (*1). Since then, the JSRT database has been widely utilized by researchers across the world for a variety of research purposes, including image processing, image compression, image display evaluation, computer-aided diagnosis (CAD), picture archiving and communication systems (PACS), as well as training and testing. - Useful for receiver operating characteristic (ROC) analysis (154 nodule-containing images and 93 non-nodule images) - High resolution (2048 × 2048 matrix size, 0.175 mm pixel pitch) - Wide dynamic range (12-bit, 4096 gray levels) - Universal image format (headerless, big-endian raw data) - Valuable for diagnostic training and testing - Supplementary information: patient age, gender, diagnosis (malignant or benign), X and Y coordinates of nodules, simple schematic of nodule location, and the subtlety of visual nodule detection
