Rectal_contours.zip

Zip archive containing all shapes stored as CSV-text files. Contains the same data as in the MATLAB file, but in text format (CSV, comma separated values). The zip file contains the file "polyhedron_faces.txt" in the root folder. This file contains an array defining the polyhedron faces. Each row in this array contains three indices (0-based) into the surface point arrays, together, these three points define a triangular face. Furthermore, the zip archive contains 37 folders, one for each patient. The folders are named "Patient ", where is a number used to refer to the patient. Each folder contains between seven and eleven csv files called "shape ", where is between 1 and 11. The first shape (number 1) is from the planning CT; the remaining shapes are recorded during the course of radiotherapy. They are not guaranteed to be in chronological order. The csv files contain 18063 lines, each with three entries. The lines represent points in 3D, and three entries in each line represent x, y and z coordinates, respectively.本压缩归档包含所有以逗号分隔值 (Comma Separated Values，简称CSV) 文本文件存储的形体数据，其内容与MATLAB格式文件完全一致，仅以文本格式存储。该压缩包的根目录下包含文件“polyhedron_faces.txt”，此文件存储用于定义多面体面片的数组。数组的每一行包含3个以0为起始索引的表面点数组下标，这三个点共同构成一个三角面片。此外，该压缩归档包含37个文件夹，每个文件夹对应一名患者。文件夹命名格式为“Patient X”，其中X为用于指代该患者的数字编号。每个文件夹内包含7至11个名为“shape X”的CSV文件，文件编号范围为1至11。编号为1的首个形体源自计划CT扫描，其余形体均在放射治疗过程中采集，但未保证按时间顺序排列。每个CSV文件包含18063行数据，每行包含3个数值项。每一行对应一个三维空间点，该行的三个数值项分别代表该点的x、y、z坐标。
