LNCTVSeg-DataSet

We retrospectively collected 440 computed tomography (CT) images from 262 patients with different imaging modalities, disease stages and treatment strategies. To protect the patients' private information, we first blurred the face region and removed all metadata about clinical and personal. Then, all files are stored with the format NIfTI-1 (32-bit floating point). Each cohort is stored as a folder and named "Internal\_Cohort", and "Testing\_Cohort\_X" ("X" is from 1 to 4), Raw CT images in the training or testing sets are stored in the "imagesTr" or "imagesTs" folders of each cohort with the name "lnctvseg\_cx\_xxxx\_yyyy.nii.gz", respectively, where "cx" denotes the center number x is the digit number from 1 to 4, "xxxx" is the index number of each patient the range is 1 to the total number of patients in "cx", "yyyy" is set to "0000" (non-contrast CT) or "0001" (contrast-enhanced CT). The corresponding labels are stored in the "labelsTr" and "labelsTs" folders with the name "lnctvseg\_cx\_xxxx.nii.gz", respectively.

本研究回顾性收集了262例不同成像模态、疾病分期及治疗方案的患者的440幅计算机断层扫描（CT）图像。为保护患者隐私信息，研究团队首先对人脸区域进行模糊处理，并移除所有临床及个人相关元数据。随后，所有文件均以NIfTI-1（32位浮点）格式存储。所有队列均以文件夹形式存储，分别命名为"Internal_Cohort"与"Testing_Cohort_X"（其中X取值为1至4）。训练集与测试集的原始CT图像分别存储于各队列的"imagesTr"与"imagesTs"文件夹中，文件命名格式为`lnctvseg_cx_xxxx_yyyy.nii.gz`。其中，"cx"代表中心编号，x取值为1至4；"xxxx"为患者索引编号，取值范围为1至对应中心的总患者数；"yyyy"用于区分扫描类型，"0000"代表平扫CT，"0001"代表增强CT。对应的标注文件分别存储于"labelsTr"与"labelsTs"文件夹中，命名格式为`lnctvseg_cx_xxxx.nii.gz`。
