Intravascular ultrasound (IVUS) uses a tiny ultrasound transducer mounted on the tip of a catheter to image the interior of blood vessels. IVUS can be used to assess vessel/lumen diameter, lesion length, help determine the amount of plaque buildup in a vessel and its composition, and check to ensure stents have been properly placed and fully deployed. It can also help measure the effectiveness of balloon angioplasty or stenting during follow ups.

In the U.S., Boston Scientific and Volcano Therapeutics are the two manufacturers with current FDA-cleared IVUS systems. Outside the U.S., Terumo also offers an IVUS system. Volcano offers two systems, the s5 and s5i, and Boston Scientifics system is the iLab. The systems are available on a cart that can be moved around to different cath labs, or as an integrated system where a controller is permanently mounted table in the lab.
