hen this paper was submitted for publication [1], co-authors Jiawen Li and Chelsea E. Munding were erroneously omitted. Furthermore, the introduction should have included a thorough summary of previous work relevant to the field of multi-frequency IVUS. The correct author list and updates to the literature review appear here. The trade-off between resolution and depth of penetration of intravascular ultrasound can be improved by the introduction of multi-frequency processing algorithms or multiple transducers with different frequencies at the tip of the catheter. This approach is particularly attractive as a cost-effective alternative to integrated intravascular ultrasound–optical coherence tomography (IVUS-OCT) devices that have previously been reported [2], [3]. The concept of using multiple transducer elements in a single IVUS catheter was previously postulated as a means of achieving multi-frequency or multi-focal performance [4]. A dual-frequency IVUS imaging device was also recently reported by prototyping a 32/67-MHz bidirectional IVUS probe [5].
