A three-dimensional tracking algorithm is designed to reduce the beam induced background for the level-1 online trigger system in the Belle II experiment using then information from central drift chamber. The z-vertex is reconstructed using linear regression to reduce the beam backgrounds which are not originated from the interaction point.
