Sonomorphology of adenocarcinoma in ex vivo flooded human lung before and after high-intensity focused ultrasound. (A) B-mode ultrasound image of adenocarcinoma in flooded lung before ex vivo high-intensity focused ultrasound insonation. Adenocarcinoma (1), flooded lung (2), thermocouple (3), and focal zone of high-intensity focused ultrasound beam (4); (B) B-mode ultrasound image after single high-intensity focused ultrasound insonation demonstrates a sharply demarcated and strongly hyperechoic sonolesion within the tumour.
