FFL-MPI-Data - simulated dataset

FFL-MPI-Data - simulated dataset A public projection imaging dataset for field-free line magnetic particle imaging 1. Data Storage Structure: Organized by phantom, each file contains all information for a single phantom, including data and metadata. Multi-domain data, such as sinograms and images, along with harmonic data for K = 2 to K = 7, are stored within data groups. Supplementary metadata facilitates user queries regarding the hardware systems and scan configurations used for phantom acquisition. Data Storage Structure:FFL-MPI-Data (v2.0)| - measured dataset | - phantom_1.h5 | - phantom_2.h5 | - ... | - phantom_100.h5 | - data/image | - data/sinogram | - data/voltage | - metadata| - simulated dataset | - train dataset | - phantom_1.h5 | - .... | - phantom_60000.h5 | - test dataset | - phantom_1.h5 | - .... | - phantom_10000.h5 | - data/image | - data/sinogram | - data/voltage | - metadata 2. Data is stored in .h5 format. Users can access data as follows: - Read image domain data: /data/image/imag (imaginary part), /data/image/real (real part) - Reading sinogram domain data: /data/sinogram/imag (imaginary part), /data/sinogram/real (real part) Metadata can also be read: - /Project_Name (project name) /Dataset_type (dataset type: measured dataset or simulated data) And other metadatas, users can view our GitHub project: BUAALGH/FFL-MPI-Data: Public projection imaging dataset for field free line magnetic particle imaging Sampling code for data reading and calling methods in the latest v2.0 version was also provided on the Github project.FFL-MPI-Data —— 仿真数据集 一款面向无场线磁粒子成像（field-free line magnetic particle imaging）的公共投影成像数据集。 1. 数据存储结构：按体模（phantom）进行组织，每个文件包含单个体模的全部信息，涵盖实验数据与元数据（metadata）。数据集包含多域数据（如正弦图（sinogram）与图像）以及K=2至K=7阶的谐波数据，均存储于数据组中。配套元数据可支持用户查询体模采集所用的硬件系统与扫描配置信息。 数据存储结构：FFL-MPI-Data（v2.0） ├─ 实测数据集 │ ├─ phantom_1.h5 │ ├─ phantom_2.h5 │ │ ... │ └─ phantom_100.h5 │ ├─ data/image │ ├─ data/sinogram │ ├─ data/voltage │ └─ metadata └─ 仿真数据集 ├─ 训练集 │ ├─ phantom_1.h5 │ │ ... │ └─ phantom_60000.h5 ├─ 测试集 │ ├─ phantom_1.h5 │ │ ... │ └─ phantom_10000.h5 │ ├─ data/image │ ├─ data/sinogram │ ├─ data/voltage │ └─ metadata 2. 数据以.h5格式存储。用户可按如下方式读取数据： - 读取图像域数据：/data/image/imag（虚部）、/data/image/real（实部） - 读取正弦图域数据：/data/sinogram/imag（虚部）、/data/sinogram/real（实部） 元数据亦可读取： - /Project_Name（项目名称） - /Dataset_type（数据集类型：实测数据集或仿真数据） 其余元数据可查阅其GitHub项目：BUAALGH/FFL-MPI-Data: Public projection imaging dataset for field free line magnetic particle imaging 最新v2.0版本的数据读取与调用方法的采样代码也已在该GitHub项目中提供。
