We propose a novel slice-to-volume registration method using Transformers trained on synthetically transformed data, which model multiple stacks of MR slices as a sequence. With the attention mechanism, our model automatically detects the relevance between slices and predicts the transformation of one slice using information from othe","authors_text":"Daniel Moyer, Elfar Adalsteinsson, Juan Eugenio Iglesias, Junshen Xu, P.
