In this study, slant helices are investigated via quasi-frame (abbv. q-frame) in four-dimensional Euclidean space E4. The notion of k-type slant q-helices is introduced in E4. Each of the q-frame fields T,Nq,Bq,Cq which makes constant angles with a non-zero fixed axis is surveyed one by one. Also, the conditions for each type of q-helices are obtained and their associations to each other are analyzed in detail.
