Systems and methods for tracking and targeting object in a patient using imaging techniques

摘要

A method for use in a medical procedure includes obtaining a contrast-enhanced image of a portion of a patient, the portion of the patient having an object, obtaining a non-contrast-enhanced image of the portion, wherein the contrast-enhanced image and the non-contrast-enhanced image are created at different times, and determining a position of the object using the contrast-enhanced image and the non-contrast-enhanced image. A method for use in a medical procedure includes obtaining a contrast-enhanced image of a portion of a patient, the portion of the patient having an object, obtaining a non-contrast-enhanced image of the portion, and determining a position of the object using the contrast-enhanced image and the non-contrast-enhanced image, wherein the act of determining the position is performed is substantially real time.
