Reality - Blood Spatter Analysis

The purpose of the ARAS Reality Blood Spatter Analysis (BSA) tool is to allow a user to determine the back trajectory and possible Area of Convergence (source) of blood spatter on a wall or floor. The tool follows the published guidelines for back tracking blood droplet trajectories as follows:

Blood spatter angle

The point of origin of the image is defined as the lower-left corner. Y runs vertically, X horizontally to the right.

The angle Theta (θ) is the angle of the long axis of the ellipse. It is also the angle of the direction of travel of the droplet when it struck the surface, looking orthogonal to the surface.

Blood spatter angle

The angle Phi (Φ) is the Impact angle, the angle between the direction of travel and the surface.
