3D MRS Digital Brain Phantom
收藏资源简介:
3D MRS数字脑部幻影数据集是由约翰斯·霍普金斯大学医学院开发的,旨在为磁共振波谱(MRS)和磁共振波谱成像(MRSI)数据的模拟提供一个全面且模块化的基础。该数据集结合了脑部解剖信息和代谢物数据,生成了一个包含所有必要信息以模拟光谱数据的数字脑部幻影。数据集的大小和分辨率可根据用户需求调整,支持1mm和3mm的分辨率。创建过程中,数据集整合了来自BigBrain-MR和MRiLab的解剖幻影,并结合了代谢物数据库中的浓度和T2值。该数据集主要应用于MRS和MRSI算法的验证和测试,旨在解决现有数据集不足和算法验证困难的问题。
3D MRS digital brain phantom dataset was developed by the School of Medicine, Johns Hopkins University, aiming to provide a comprehensive and modular foundation for the simulation of Magnetic Resonance Spectroscopy (MRS) and Magnetic Resonance Spectroscopic Imaging (MRSI) data. This dataset combines brain anatomical information and metabolite data to generate a digital brain phantom that contains all necessary information for simulating spectroscopic data. Its size and resolution can be adjusted according to user requirements, supporting resolutions of 1mm and 3mm. During its development, the dataset integrates anatomical phantoms from BigBrain-MR and MRiLab, and incorporates concentrations and T2 values from metabolite databases. This dataset is primarily used for the validation and testing of MRS and MRSI algorithms, aiming to address the issues of insufficient existing datasets and difficulties in algorithm verification.
