This is a data set of blood spatter patterns scanned at high resolution, generated in controlled experiments. The spatter patterns were generated with a rifle or a handgun with varying ammunition. The resulting atomized blood droplets travelled opposite to the bullet direction, generating a gunshot backspatter on a poster board target sheet. Fresh blood with anticoagulants was used; its hematocrit and temperature were measured. The main parameters of the study were the bullet shape, size and speed, and the distance between the blood source and target sheet. Several other parameters were explored in a less systematic way. This new and original data set is suitable for training or research purposes in the forensic discipline of bloodstain pattern analysis.
这是一组在对照实验中生成的、以高分辨率扫描的血液飞溅模式数据集。飞溅模式是使用配备不同弹药的步枪或手枪产生的。产生的雾化血滴朝着与子弹方向相反的方向移动，在硬纸板靶板上产生枪击后溅血。使用了添加抗凝剂的新鲜血液；测量了其血细胞比容和温度。该研究的主要参数是子弹的形状、尺寸和速度，以及血源与靶板之间的距离。还以不太系统的方式探索了其他几个参数。这个全新的数据集适用于血迹模式分析法医学领域的培训或研究目的。
