Abstract

Imaging systems and methods for imaging assisted interventional procedure that receive images of a region of interest, that automatically detect in the images a contrast agent puff as it courses through the region of interest, and that generate a display including a video replay loop of contrast enhanced images based on the automatic detection of the contrast agent puff.

Description

technical field [0001] The technical field relates generally to contrast-enhanced imaging of a patient's vasculature. In particular, the technical field relates to imaging contrast injection during interventional procedures. Background technique [0002] US 9545237 discloses a system for recording and displaying the geometry of blood vessels or vascular structures in general, into which an injection catheter is inserted. A guidewire tip is passed over a guidewire to examine and treat narrowing of coronary arteries. The position of the guidewire tip can be detected by means of X-rays, but it is difficult to visualize the stenosis because the coronary arteries are usually not visible with respect to X-ray radiation. Thus, contrast agents may be provided by injecting catheters to increase the contrast of vascular structures, particularly including narrowed coronary arteries. [0003] During the diagnostic or examination phase, clinicians inject large doses of contrast materi...
