In this work, we present a Keyhole method for fast Time Of Flight (TOF) imaging. We compare it with a recently published segmented k-space filling scheme. Moreover, we demonstrate the feasibility of combing the Keyhole and segmented methods for further acceleration. Such a hybrid TOF can be potentially suited for high-resolution angiograms at ultra-high field.
