Ultrasound-Guided Near-Infrared Optical Tomography

**Semantic type:** Diagnostic Procedure

**Definition:** An imaging modality that combines ultrasound imaging with diffused light imaging by near-infrared (NIR) optical tomography to obtain coregistered ultrasound and NIR diffusive light images in order to improve optical imaging reconstruction and location certainty. The use of NIR in this combination can also be used to assess functional parameters of a tissue.
