Evaluation of a New Ultrasound Thoracoscope for Localization of Lung Nodules in Ex Vivo Human Lungs

The ultrasound thoracoscope can be used to localize nodules in resected human lungs. The clarity of the tumor boundaries is influenced by the tumor type and depth and the underlying pulmonary disease. Complete lung deflation and the use of 10 MHz ultrasound frequency optimize the visualization of target tumors.
