The need for optimal bolus timing in contrast enhanced imaging of the liver can be avoided by using a high temporal resolution acquisition. The selection of an optimal arterial phase requires a manual inspection of a large number of images. An algorithm is presented here that detects the optimal arterial phase in these sets of images, allowing immediate visualization of the relevant liver lesion enhancement information.
