Use of Intra-Operative Shear Wave Ultrasound Vibrometry for Characterization of Esophageal Malignant Tumors


About this study

Using the analysis of group velocity for a screening application and then higher order analysis based on the elastic and viscious components of the shear modulus may allow discrimination between extent of tumor invasion through the esophageal wall if appropriately correlated with pathological findings.
