Title:
DETECTION OF FIDUCIALS IN A CLINICAL IMAGE
Document Type and Number:
WIPO Patent Application WO/2018/163105
Kind Code:
A3
Abstract:
The instant disclosure relates to systems and methods for identifying fiducial markers on one or more images of an anatomical region of a patient. Prior to the identification of the fiducial markers, other objects are identified and removed. In particular, some embodiments are directed toward the detection of fiducial markers in the presence of catheters and other medical devices in a fluoroscopic image. In such an embodiment, identifying and removing the medical devices from the clinical image aids in properly identifying the fiducial markers.
