HCA Healthcare. has filed a patent for methods and systems that dynamically visualize an object of interest, such as the vasculature of a patient. The invention involves generating a 3D model of the object and using it to create a roadmap with information about the object’s properties. The method also includes determining the location of an interventional device used in treating the object, obtaining non-contrast-enhanced x-ray image data, and overlaying the transformed roadmap on the image data for display.

A recently filed patent (Publication Number: US20230309943A1) describes a method for generating an image of an object of interest in a patient's vasculature. The method involves several steps to create a three-dimensional (3D) model of the object of interest using 3D angiographic imaging data. This model is then used to generate a roadmap that characterizes the properties of the object, such as centerlines, contours, and image masks.

The method also includes determining a reference location for the tip of an interventional device being used in a procedure to treat the object of interest. Non-contrast-enhanced x-ray image data of the object is obtained, and the location of the tip of the interventional device is determined in this x-ray image data. A particular roadmap is selected, and the reference location and the location of the tip of the device are used to transform the roadmap. Finally, a visual representation of the transformed roadmap is overlaid on the non-contrast-enhanced x-ray image data for display.

The patent also includes additional claims, such as the use of two-dimensional or three-dimensional roadmaps, obtaining contrast-enhanced x-ray image data, and processing the image data to determine the phase of the cardiac cycle. The method can compensate for motion, such as breathing or cardiac motion, and can be applied to live image sequences acquired without a contrast agent. The interventional device can be a guiding catheter, guide wire, or other intraluminal device or instrument.

The patent also describes a system for implementing the method, including a processor, imaging acquisition subsystem, and display subsystem. Additionally, a non-transitory program storage device is mentioned, which contains executable instructions for performing the method.

Overall, this patent presents a method and system for generating images of objects of interest in a patient's vasculature using 3D angiographic imaging data and non-contrast-enhanced x-ray image data. The method allows for the visualization and overlay of roadmaps onto the x-ray images, aiding in interventional procedures.
