Purpose: The purpose of this first-in-man study is to directly measure thoracic tumor immobilization by high frequency percussive ventilation (HFPV).
Methods: In an IRB approved protocol (IRB # 2017-046) we screened patients with conspicuous lung tumors that exhibited motion >10 mm to undergo kV fluoroscopy with HFPV. Two sets of consecutive AP (anterior posterior) fluoroscopy frames were acquired during multiple breathing cycles for free- and HFPV- breathing. All images were acquired using our kV source/panel of the therapeutic linear accelerator. Percussions were delivered via the intrapulmonary percussive ventilation device (IPV-2C) and phasitron (Percussionaire Corp., Sagle, Idaho). The baseline settings for …
