Automated image cropping for enhanced automatic device-to-image registration

A system comprising:

• a medical device including fiducial markers;
• and
• a computing system including a computer-readable storage medium storing executable program instructions, which when executed by the computing system, cause the computing system to:
• obtain image data of a subject and the medical device, wherein the image data includes three-dimensional image data;
• generate information representing a three-dimensional shape based on a planned insertion point for performing a medical procedure;
• apply a cropping process to the image data to generate cropped image data corresponding to a portion of the image data based on the three-dimensional shape, the cropped image data including image data of at least two of the fiducial markers;
• detect fiducial marker objects within the cropped image data;
• and
• register the fiducial marker objects by matching a model of the fiducial markers with the fiducial marker objects,
• wherein, in a case where the portion of the image data includes artifact image data, the artifact image data is removed in the cropped image data.

A computer-readable storage medium storing executable program instructions, which when executed by a computing system with one or more processors, cause the computing system to:

• obtain image data of a subject and a medical device, the medical device including fiducial markers, wherein the image data includes three-dimensional image data;
• generate information representing a three-dimensional shape based on a planned insertion point for performing a medical procedure;
• apply a cropping process to the image data to generate cropped image data corresponding to a portion of the image data based on the three-dimensional shape, the cropped image data including image data of at least two of the fiducial markers;
