The Winston-Lutz (WL) test is a commonly used method to localize the isocenter of a linear accelerator (linac) in radiation therapy. 1 Compared with other methods, such as room lasers and light field crosshairs, the WL test correlates the radiation fields directly with the object being irradiated. Traditional WL tests use … WebbAssess your knowledge of the nervous system by selecting the correct answer in the following questions.
