We have developed a new algorithm for fast region of response rendering in Positron Emission Tomography (PET). The algorithm can be applied efficiently to Expectation Maximization (EM) techniques that include per-event probability distributions with shapes more complex than symmetric tubes of response. The algorithm is generic for any system geometry and draws the scalar field associated to a generic input kernel with a constant cut-off threshold independent from the actual kernel shape.
