Medical uses of ultrasound came shortly after the end of World War II. However, real‐time ultrasound imaging originated in the late 1960s and early 1970s when Bom et al. [1] pioneered the development of linear array transducers for use in the cardiovascular system. The first two‐dimensional catheter imaging system was designed in 1972 using a solid‐state transducer array of 32 elements arranged radially at the tip of a 9 Fr catheter [2]. By the late 1980s, Yock et al. [3] had successfully miniaturized a single‐transducer system that could be placed within coronary arteries. Ever since, intravascular ultrasound (IVUS) has become an increasingly important catheter‐based imaging technology providing both practical guidance for percutaneous coronary interventions (PCI) as well as many different clinical and research insights [4,5]. IVUS directly images the atheroma within the vessel wall, allowing reproducible measurement of plaque size, distribution, and to some extent its composition.
