The invention generally relates to devices and methods that allow an operator to obtain real-time images of a luminal surface prior to, during, and after an intraluminal procedure, including while a tool is engaged with the luminal surface. An imaging system of the invention may include a first elongate member that includes a first imaging element and a catheter that includes a second imaging element. The first imaging element is an optical-to-acoustic transducer, and the second imaging element is an optical-to-acoustic transducer. The catheter also defines a lumen and includes an ablation element. The catheter is configured to receive at least a portion of the elongate member within the lumen and is configured to move along a path of the elongate member.
