Classification: CPC A  G | IPC A

Claim 0:
1. Apparatus for medical imaging comprising:
an x-ray machine;
a tracking system operative to determine pose and position of the x-ray machine;
a system comprising one or more data processors connected to receive image data for images acquired by the x-ray machine and pose and position data from the tracking system corresponding to the images; and
a display;
wherein the system is configured by machine-readable instructions executable by the one or more data processors to generate long calibrated two-dimensional radiographic views by:
prompting a user to position the x-ray machine relative to a patient in a first orientation, such that the x-ray machine has a known relationship to anatomical planes of a body of the patient and/or an operative anatomy;
prompting the user to position the x-ray machine relative to the patient in a second orientation;
calculating a three-dimensional vector representation of one or more of the anatomical planes based at least in part on a beam geometry of the x-ray machine from the respective first and second orientations of the x-ray machine, where each plane is orthogonal to the other planes;
transforming images of the patient acquired by the x-ray machine in the first and second orientations onto the one or more anatomical planes based on the vector representation, the beam geometry of the x-ray machine, and the positions and poses of the x-ray machine corresponding to the images;
displaying on the display at least two long views each one 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.
