AI Technical Summary

Technical Problem

Conventional interventional imaging systems, such as C-arm and biplane fluoroscopic systems, suffer from poor temporal resolution, geometric inaccuracy, and limited tomographic capabilities, making them suboptimal for precise instrument-anatomy visualization and tissue parameter estimation during procedures like ablation.

Method used

A multisource X-ray imaging system with multiple X-ray sources and detectors configured in arcs or rings, allowing for high temporal resolution and volumetric reconstruction, combined with a robotic positioning platform for precise instrument guidance and tissue parameter measurement.

Benefits of technology

Enables 3D interventional guidance with improved temporal resolution, tissue parameter measurement, and flexibility for both interventional and diagnostic imaging, reducing geometric inaccuracy and dose to patients and personnel.

Abstract

A multisource interventional X-ray imaging system including a ring assembly is disclosed. The ring assembly may include a first arc including a plurality of X-ray sources, and a second arc including a plurality of detectors. The X-ray sources and the detectors may be arranged to view a patient. Further, the ring assembly may axially rotate or wobble by a maximum angular displacement that is equivalent to a distance between adjacent X-ray sources.
