Systems and methods for image-based object modeling using multiple image acquisitions or reconstructions

摘要

Systems and methods that involve integrating imaging data from multiple sources to create a single, accurate model of a patient's anatomy. One method includes receiving a representation of a target object for modeling; determining one or more first anatomical parameters of the target anatomical object from at least one of one or more first images of the target anatomical object; determining one or more second anatomical parameters of the target anatomical object from at least one of one or more second images of the target anatomical object; updating the one or more first anatomical parameters based at least on the one or more second anatomical parameters; and generating a model of the target anatomical object based on the updated first anatomical parameters.

1. A computer-implemented method of modeling at least a portion of a patient's vasculature, using a computer system, the method comprising:
receiving one or more three-dimensional images of a portion of a patient's coronary vasculature; receiving one or more two-dimensional images that are generated independently from the one or more three-dimensional images, wherein the one or more two-dimensional images include images of the portion of the patient's coronary vasculature; determining, from the one or more three-dimensional images, one or more three-dimensional image based anatomical parameters of the portion of the patient's coronary vasculature; determining, from the independently-generated one or more two-dimensional images, one or more two-dimensional image based anatomical parameters of the portion of the patient's coronary vasculature; updating the one or more three-dimensional image based anatomical parameters based at least on the one or more two-dimensional image based anatomical parameters; and generating a model of at least the portion of the patient's coronary vasculature based on the updated three-dimensional image based anatomical parameters.
