Systems and methods for producing real-time calibrated stereo long radiographic views of a patient on a surgical table

A method of gathering and processing intraoperative images—the method implemented by a system comprising one or more processors, the system connected to an X-ray machine, a tracking system, and a display—the method comprising:

• prompting a user to position the X-ray machine relative to a patient in a first orientation;
• determining a pose and position of the X-ray machine in the first orientation using a tracking system;
• acquiring one or more images using the X-ray machine while in the first orientation;
• prompting the user to position the X-ray machine relative to the patient in a second orientation;
• determining a pose and position of the X-ray machine in the second orientation using the tracking system;
• acquiring one or more images using the X-ray machine while in the second orientation;
• receiving image data for one or more images acquired by the X-ray machine and pose and position data from the tracking system corresponding to the images;
• calculating a world coordinate system based on the extrinsic parameters of anterior/posterior (AP) and lateral (LAT) views in the C-arm, using an XY plane as an AP anatomical plane and a YZ plane as a LAT anatomical plane;
• transforming images of the patient acquired by the X-ray machine in the first and second orientations onto corresponding anatomical planes based on a vector representation, a beam geometry of the X-ray machine, and the positions and poses of the X-ray machine corresponding to the images;
• and
• displaying on the display connected to the system at least two long views generated by the system, each long view corresponding to one or more of the one or more anatomical planes, each of the one or more long views comprising a plurality of the transformed images.
