模体扫描影像数据

主要获取模体扫描影像数据每组数据中细分为直接采集的投影数据集和重建CT图像数据集。每组投影图像数据集包含1000张投影图像，投影图像的像素数量为1024×1024，像素尺寸为0.154mm×0.154mm。投影图像的采集参数为扫描电压：80 kVp；扫描电流：0.6 mA；扫描帧率：25 FPS；扫描转速：2 r/min。每组数据的重建CT图像数据为使用标定模体标定的几何参数进行滤波反投影重建得到的CBCT图像。投影图像为二维图像，数据类型为uint16，大小为1024×1024，单张投影数据大小为2.00MB。CBCT图像为三维图像，数据类型为float32，数据量为2G。

This dataset primarily comprises phantom scan imaging data, with each group of data subdivided into two subsets: directly acquired projection dataset and reconstructed CT image dataset. Each projection image dataset contains 1000 projection images, each with a resolution of 1024×1024 pixels and a pixel size of 0.154 mm × 0.154 mm. The acquisition parameters for the projection images are as follows: scanning voltage of 80 kVp, scanning current of 0.6 mA, frame rate of 25 FPS, and rotation speed of 2 r/min. The reconstructed CT image data for each group consists of cone-beam CT (CBCT) images obtained through filtered back-projection (FBP) reconstruction using geometric parameters calibrated with a calibration phantom. The projection images are 2-dimensional (2D) images with a data type of uint16, a resolution of 1024×1024, and a single-projection data size of 2.00 MB. The CBCT images are 3-dimensional (3D) images with a data type of float32 and a total dataset size of 2 GB.
