  • Impact of Continuous Positive Airway Pressure on Breathing Motion Amplitude Rochester, Minn.

    The purpose of this study is to measure the extent that breathing motion is reduced in healthy volunteers after continuous positive airway pressure (CPAP) used. If CPAP administration will significantly reduce breathing motion, this may help cancer patients who are undergoing proton radiotherapy, so they may not have to hold their breath during the procedure.
  • Pilot Study on Use of Navigator Echoes for 4D-MRI Rochester, Minn.

    The general aim of this proposal is to evaluate new non-significant risk (NSR) MRI technology in a clinical setting, specifically the use of preclinical (non-FDA-approved) sequences (including but not limited to bSSFP, SSFSE) which have been modified from their standard counterparts to include interleaved 1D body navigator pulses.
  • Ultrasound Evaluation of the High-Frequency Percussive Ventilation Based Proton Therapy Motion Mitigation Rochester, Minn.

    The purpose of this study is to evaluate the effectiveness of the high frequency percussive ventilation (HFPV) technique and demonstrate tolerable and reproducible thoracic immobilization with less than 5 mm residual motion.
