  1. Purpose of the Interactive Breath-Hold Control System To improveCT-guided biopsies of the lung or upper abdomen by allowing consistent, optimal visualization of the target lesion throughout procedures where respiratory motion is a problem.

  2. Significance of Respiratory Motion During normal breathing, lung and upper abdomen lesions can move 1-6 cm in SI direction

  3. Breath Hold - Assisted Lung Biopsy to Avoid Rib Nodule accessible through intercostal space Nodule behind rib SMALL BREATH DEEPER BREATH

  4. Breath Hold - Assisted CTF Biopsy(Previous unsuccessful biopsy at outside hospital due to motion) 1 cm nodule Diagnosis: Metastatic Melanoma

  5. Breath Hold-Assisted Biopsy of Lesions in Difficult Locations Aorta 9mm Para-Aortic Lung Nodule

  6. Potential Applications • Tumor Ablation • Radiation Therapy Protocols • Robotic Intervention • Intratumoral injections (gene rx) • Fluid Aspiration and Drainage • Chest Imaging (reproducibility) • MRI: Spectroscopy, FUS, MRC • PET/CT • CT perfusion studies • Solitary Pulmonary Nodule • Liver • Pancreas • Renal

  7. Clinical Benefits • The Breath Hold is: • Sensitive and reliable for monitoring respiratory levels and providing patient feedback • Allows optimal visualization of the target lesion throughout the procedure • Enables procedures to be simpler to perform • Benefits of the Breath Hold system include: • Statistically significant  in CTF exposure time, patient radiation dose, and needle puncture attempts • Fewer procedure-related complications, particularly a  in pneumothorax rate •  needle placement time and total procedure time
