Purpose of the Interactive BreathHold Control System To
Purpose of the Interactive Breath-Hold Control System To improve CT-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.
Significance of Respiratory Motion During normal breathing, lung and upper abdomen lesions can move 1 -6 cm in SI direction

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
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
