DYNAMITE: DYNamic phAse-contrast MIcro-Tomography of the human middle Ear
收藏资源简介:
These are datasets of dynamic microtomography conducted at the TOMCAT beamline (SLS, PSI). The samples were fresh-frozen human ear, acoustically stimulated, so vibrating. The table below give the correspondence between datasets (number and block) and sample name + acoustic stimulation parameter (intensity = sound pressure level in decibels and frequency in hertz). The h5 file is the set of projections for the different tomography angles, taken during stimulation of the sample. The waveform.dat file can be used to perform the retrospective gating and sort the projection back according to their acquisition time (corresponding to a specific phase of vibration).

本数据集为在TOMCAT光束线(瑞士光源SLS,保罗谢尔研究所PSI)开展的动态显微断层扫描数据集。 实验样本为经新鲜冷冻处理的人类耳部组织,且在声学刺激下处于振动状态。 下表展示了数据集(编号与区块)与样本名称、声学刺激参数(强度为以分贝计的声压级,频率为以赫兹计的振动频率)之间的对应关系。 h5格式文件包含样本受刺激过程中采集的、对应不同断层扫描角度的投影数据集。 waveform.dat文件可用于开展回顾性门控处理,并根据采集时间(对应振动的特定相位)对投影数据进行重排序。 数据集对应表 数据集编号 样本名称 区块 刺激强度 刺激频率 82 Fresh1 无 125 127 83 Fresh1 无 125 127 84 Fresh1 无 125 127 88 Fresh1 无 140 127 89 Fresh1 无 140 127 90 Fresh1 无 140 127 09 Fresh3 _000 120 128 09 Fresh3 _001 120 128 09 Fresh3 _002 120 128 09 Fresh3 _003 120 128 10 Fresh3 _000 110 128 10 Fresh3 _001 110 128 10 Fresh3 _002 110 128 10 Fresh3 _003 110 128 89 Fresh7 _001 110 128 90 Fresh7 _001 120 128 112 Fresh8 _001 110 128 113 Fresh8 _001 120 128 03 B-Fresh1 _002 110 128 04 B-Fresh1 _002 120 128 144 B-Fresh2 _000 110 128 144 B-Fresh2 _001 110 128 145 B-Fresh2 _000 120 128 145 B-Fresh2 _001 120 128 62 B-Fresh3 _000 110 128 62 B-Fresh3 _001 110 128 63 B-Fresh3 _000 120 128 63 B-Fresh3 _001 120 128
