Deformation is a critical characteristic of atomic nuclei,reflecting the correlations within finite quantum many-body sys-tems.The study of deformation is a key research area in nuclear physics.This article reviews the methodology used to image nuclear deformation in high-energy heavy-ion collisions.It delineates the techniques used to extract deformation parameters from these collisions,offering a detailed overview of recent advancements in understanding how nuclear defor-mation impacts heavy-ion collisions,particularly in relation to collective flow observables.Studying deformation not only presents a novel approach for extracting information about nuclear structure,complementing lower-energy methods,but it also helps constrain the initial conditions of heavy-ion collisions.The potential for forging an interdisciplinary connection between high-energy nuclear collisions and lower-energy nuclear structures is discussed.
