Medium Velocity Impact Spatter (MVIS) A bloodstain pattern that is caused by medium velocity impact to a blood source such as that caused by blunt force trauma with a weapon.
Parent Drop A drop of blood from which a wave, cast-off, or satellite spatter originated.
Passive Drop Bloodstain drop(s) created or formed by the force of gravity acting alone.
Point of Convergence The common point on a two dimensional surface, over which the directionality of several blood drops can be retraced.
Point of Origin The common point in a three dimensional space to which the trajectories of several blood drops can be retraced.
Satellite spatter Small droplets of blood that are distributed around a drop or pool of blood as a result of the blood impacting the target surface.
Spine The pointed or elongated stains which radiate away from the central area of a bloodstain.
Swipe Pattern The transfer of blood from a moving source onto an unstained surface.
